What is Embryo Freezing?

What is Embryo Freezing?

The procedure of Embryo freezing is done along with fertility treatment in an IVF laboratory.  It allows people to store gametes, reproductive tissue and embryos for later use. The first successful pregnancy resulting from freezing a healthy embryo took place in the 1980s. Since then, many people have frozen embryos and used them later. If your doctor has given option for frozen embryo transfer you must know the risks and advantages.

Embryo freezing is a laboratory procedure which begins with injection of hormones and other medications to stimulate the production of potentially fertile eggs. The eggs are then extracted from the ovaries, either for fertilizing in a lab or for freezing. A person may wish to freeze their eggs. Or, they may wish to use them at once to become pregnant. Fertilisation of eggs with sperm can be achieved either with in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI).  Often with in vitro fertilisation (IVF) or Intracytoplasmic sperm injection (ICSI) treatment, there may be good quality embryos left over after embryo transfer. Instead of discarding them, there is the option to freeze them to use in the future. A person can also freeze eggs and sperm, which are not fertilized. Embryos can be frozen to preserve fertility so it may be possible to have a baby at a later date.

When freezing is recommended?

Embryo cryopreservation is useful for surplus embryos during in vitro fertilisation. Patients who fail to conceive may become pregnant using frozen embryos in subsequent cycles. Successful patients in IVF treatment may come back later for frozen embryo transfer to achieve a sibling pregnancy.

 

Surplus oocytes or embryos resulting from fertility treatments may be stored for oocyte donation or embryo donation to another woman or couple. At times embryos may be created, frozen and stored specifically for transfer and donation by using donor eggs and sperm.

 When the endometrium is not ready for implantation embryos may be frozen for use at later date. This situation arises in patients with thin endometrium or oocyte donation and surrogacy programme.

 There are certain situations like ovarian hyper stimulation when fresh embryo transfer becomes risky for the woman’s health. In this scenario embryos are frozen for later use.

 Young patients undergoing cancer therapy can freeze their eggs, ovarian or testicular tissue for future use. Rare instances where mother is not fit to undergo a pregnancy may freeze embryos. They can come later for embryo transfer when the health issue is resolved.

How do people freeze embryos?

 

Cryo-preservation or cryo-conservation is a process where cells, tissues or organs are preserved by cooling to very low temperatures. Cryopreservation was applied to humans beginning in 1954 with three pregnancies resulting from the insemination of previously frozen sperm. There are two ways of freezing-

 

Slow freezing: This involves placing the embryos in sealed tubes, then slowly lowering their temperature. It prevents the embryo’s cells from ageing and reduces the risk of damage. However, slow freezing is time-consuming, and it requires expensive machinery.

 

Vitrification: In this process, the tissue is frozen after cryoprotection. The embryos are frozen so quickly that the water molecules do not have time to form ice crystals. This helps protect the embryos and increases their rate of survival during thawing. In the laboratory, large tanks filled with liquid nitrogen are available in which embryos are stored. The embryos remain in sealed containers at temperatures of -321ºF. At this temperature, almost no biological processes, such as ageing, can occur.

  The tanks that contain frozen embryos are monitored 7 days a week. Each tank gets a physical inspection daily, looking for problems or signs of problems. The quantity of nitrogen in the tank is assessed as a means of monitoring for a possible slow leak or an impending tank failure. The nitrogen in the tank is topped up daily, since it continuously evaporates at a slow rate.

When to freeze embryos?

 

Not all embryos are suitable for freezing, so only good quality embryos will be chosen to freeze. Embryos can be frozen at different stages of their development – when they’re just a single cell, at the two to eight cell stage or later in their development (called the blastocyst stage). Eggs and sperm can also be frozen with out fertilising.

 

What is the success rates of thawing frozen embryos?

 

The process of thawing an embryo after cryopreservation has a relatively high success rate, and research suggests that women who use thawed embryos have good chances of delivering healthy babies.

 

How long can embryos stay frozen?

 

Procedures for human embryo freezing were developed in 1984 and only went into widespread use in the late 1980s. This means that the longest time a human embryo has been stored is 25-30 years and, typically, patients that have left embryos in storage for this long are not coming back for them.

In theory, a correctly frozen embryo can remain viable for any length of time. But different laws regulate length of freezing in different countries. Most countries allow freezing up to 10 years.

 

The embryos remain in sealed containers at temperatures of -321ºF. At this temperature, almost no biological processes, such as aging, can occur.

 

Frozen or fresh embryos – which is better?

 

A study published in the International Journal of Reproductive Biomedicine looked at the results of over 1,000 instances of embryo transfer involving either fresh or frozen embryos.

The researchers found no statistical difference between the types of embryos, in terms of pregnancy rates or fetal health.

 

Freezing of human sperm, eggs and embryos @ Femelife

 

Within the laboratory at Femelife we have a tissue bank where we freeze and store oocytes (eggs), sperm and embryos for our patients. The bank has personnel and computerised system for full time monitoring. The procedure is done under supervision of the lab director, and is licensed by the ICMR, Govt of India. All tissue in the bank is stored frozen in liquid nitrogen at a temperature of -196C in vacuum lined tanks that are computer controlled and monitored 7 days a week with a dedicated alarm system. The embryologists are responsible for maintaining the bank and no other employee has access to it.

 

The process of freezing eggs vs. freezing embryos

 

The egg freezing procedure and the embryo freezing procedure both start the same basic way with hormone medication, injected over for 8–12 days, that stimulates the ovaries to produce multiple eggs. Freezing multiple eggs increases the chances of finding healthy eggs later. Study have shown that embryos survive the freeze thaw process better than eggs. The freezing of eggs is a recent procedure and may need further development for wide usage.

  

What are the risks associated with cryopreservation of embryos and human gamete?

 

Risk of contamination

 Since viruses and bacteria can also survive at cryogenic temperatures it needs special attention. The risk of cross-contamination, i.e., transfer of bacteria or other microorganisms from liquid nitrogen to stored samples, is should be taken care. Some investigators have suggested that liquid nitrogen should be sterilised in order to prevent such contamination when so-called open cryodevices, which bring the sample in direct contact with the liquid, are utilised.

 Risk of reduced or lost viability

 Long-term storage does not impact viability/developmental potential of slow-frozen embryos. Cryostorage appears to be safe for slow-frozen oocytes as well.

 

Risk of specimen loss

 In contrast to the risk of infection or time-related decrease in viability, under current practices the risk of loss of cryopreserved gametes and embryos due to human error or equipment failure is relatively high. It is the responsibility of the IVF laboratory to take proper care of the procedure.

 Risks inherent in shipment and handling

 At times, frozen eggs or embryos need transportation for further use according to patient convenience. The shipping procedure carries risk of vessels being exposed to elevated ambient temperature and air pressure, vibration/other physical shock, and horizontal storage.

 A two-step removal of vitrified samples, during which the sample is held in the neck of a dewar in nitrogen vapour for 15 seconds, leads to reduced viability due to thermodynamic instability and devitrification at relatively low temperatures. Cross country transportation of cryopreserved eggs and embryos are guarded by certain laws.

        Embryo freezing is a type of fertility preservation. It may be useful for women with cancer who want to have children after having radiation therapy, chemotherapy, or certain types of surgery, which can cause infertility. Also, called embryo banking and embryo cryopreservation it is widely used in IVF treatment.

Male factor Infertility – Causes and Treatment

Male factor Infertility – Causes and Treatment

 

How common is male factor infertility and what proportion of infertility in the couple is attributable to the male?

Of all infertility cases, approximately 40–50% is due to “male factor” infertility and as many as 2% of all men will exhibit suboptimal sperm parameters.

The rates of infertility in less industrialised nations are markedly higher and infectious diseases are responsible for a greater proportion of infertility.

The fertility rate in men younger than age 30 years has also decreased worldwide by 15%.

Male infertility

Male infertility

Is it necessary for all infertile men to undergo a thorough evaluation?

 If you are facing difficulty in conceiving then semen analysis should be done at the earliest.

Male infertility is commonly due to deficiencies in the semen, and semen quality is used as a surrogate measure of male fecundity.

Males with sperm parameters below the WHO normal values are considered to have male factor infertility.

The most significant of these are low sperm concentration (oligospermia), poor sperm motility (asthenospermia), and abnormal sperm morphology (teratospermia).

Semen analysis remains the single most useful and fundamental investigation with a sensitivity of 89.6%, that it is able to detect 9 out of 10 men with a genuine problem of male infertility.

 

What is the clinical value of traditional semen parameters?

Males with sperm parameters below the WHO normal values are considered to have male factor infertility.

The most significant of these are low sperm concentration (oligospermia), poor sperm motility (asthenospermia), and abnormal sperm morphology (teratospermia).

What key male lifestyle factors impact on fertility (focusing on obesity, heat and tobacco smoking)?

Cigarette smoke is a common somatic cell carcinogen and mutagen, and may adversely affect male reproduction factors.

Obesity is also linked to subfertility due to alteration in the hormone environment. Constant exposure to lead for instance, without safety measures, predisposes such individuals to low fertility.

Men who are exposed to high temperature at their workplace – welders, dyers, blast furnace workers and those employed in cement and steel factories – are more prone to infertility. A 1° elevation in testicular temperature leads to 14% depression of spermatogenesis.

Do supplementary oral antioxidants or herbal therapies significantly influence fertility outcomes for infertile men?

 Oxidative stress in the seminal fluid causes damage of the sperm plasma membrane and loss of its DNA integrity. Normally, a balance exists between concentrations of reactive oxygen species and antioxidant scavenging systems. If oxidative damage exceeds natural scavenging capacity then it affects sperm parameters. High dosage of vitamin C & E may rescue from such damage and increase fertility in male factor infertility.

 

What are the evidence-based criteria for genetic screening of infertile men?

Genetic testing is required in all severely oligospermic and non-obstructive azoospermic men. Such men demonstrate small testes and increased FSH. Chromosome structural and numeric abnormalities, YCMD, and other genetic mutations have been implicated in male subfertility. These men may benefit from genetic testing.

How does a history of neoplasia and related treatments in the male impact on reproductive health and fertility options?

Cancer, or post cancer treatments, can interfere with male factor fertility and reduce the ability to have children. Different types of treatments can have different effects.

Higher doses of cancer drugs are more likely to cause permanent fertility changes. The combinations of drugs can have greater effects. The risks of permanent infertility are even higher when males are treated with both chemo and radiation therapy.

 

What is the impact of varicocele on male fertility and does correction of varicocele improve semen parameters and/or fertility?

Varicocele is among the most common causes of male infertility. Varicocele affects fertility and sperm quality in some, but not in all men. The adverse effect of varicocele on sperm parameters may be due to increased testicular temperature, increased pressure, or reduced blood flow.

Effectiveness of varicocelectomy is however not proved and hence not practiced in many infertility setup.

Revolution in IVF Treatment: Towards better techniques & Success in IVF

Revolution in IVF Treatment: Towards better techniques & Success in IVF

Success in IVF Treatment

Lesley Brown was a patient with nine years of primary infertility who sought the assistance of Patrick Steptoe and Robert Edwards at the Oldham General Hospital in England in 1970’s. At that time, she was unaware of the historical revolution in IVF treatment she was going to be associated with. Fertilisation of oocytes outside the human body, a process known as in vitro fertilisation (IVF), was considered entirely experimental and unsuccessful around that period. Without using medications to stimulate her ovaries, Lesley Brown underwent laparoscopic egg retrieval, with her single egg fertilised in the laboratory, and later transferred back into the uterus. The embryo transfer resulted in the first live birth from IVF, a daughter Louise Brown, who was born in July 1978.

Fertility Breakthrough

Fertility Breakthrough

Introduction of ovarian stimulation and Success with traditional IVF

 The success of IVF treatment with unstimulated cycles yielded on average 0.7 oocytes per retrieval and an overall pregnancy rate of 6% per initiated cycle at that time. Stimulated IVF cycles with human menopausal gonadotropin (hMG) prior to laparoscopic egg retrieval was extensively studied at the Jones Institute after 5 years. Its widespread use led to dramatic improvement in oocyte yield per retrieval and pregnancy rates. Between 1980 and 1983, the use of hMG with IVF treatment resulted in an average recovery of 2.1–2.6 oocytes per retrieval and increasing pregnancy rates of 23.5% per retrieval in 1982 and 30% in 1983.

Pituitary desensitisation by administration of gonadotropin releasing hormone agonist (long protocol) prior to ovarian stimulation with hMG was first reported in 1984. Effective suppression with this protocol decreased the incidence of premature ovulation to about 2% and significantly improved overall pregnancy rates with IVF.

Pregnancy rates in women using donor oocytes are known to be as high as 50% per embryo transfer in recipients across all age groups. Indeed, women in their sixties have also given birth with donor oocytes, demonstrating that the postmenopausal uterus maintains the capacity to support pregnancies if provided adequate hormonal support. Despite these unresolved issues, donor IVF remains an integral part of modern ART, and accounts for 11.6% of the IVF treatment cycles.

 

Development of different types of protocol

Development of different types of protocol

Freezing techniques in IVF

Intense efforts to develop various freezing/thawing techniques and cryoprotective agents eventually resulted in the first reported human pregnancy from a frozen embryo in 1983, which unfortunately ended in premature rupture of the membranes and termination of pregnancy at 24 weeks of gestation. Despite the initial set back, technology in cryopreservation continued to improve throughout the 1980s, leading to an increase in embryo survival rate and pregnancy rates. During the initial years of experimentation, at best approximately 50% of embryos survived the freeze/thaw process and resulted in a pregnancy rate of 13.4% per embryo transfer procedure, as only 4.6% of the individual thawed embryos implanted

ICSI revolutionised Artificial Reproductive Techniques

As the pregnancy rate of IVF improved over the last decade from 22.3% in 1995 to 33% in 2003. In 2003, GIFT and ZIFT were used in only 0.1% and 0.4% of ART cycles, while IVF represented the remaining 99.5% of cases.

 

The first pregnancies using embryos generated by ICSI were reported in 1992 (Palermo et al 1992) and the procedure has been applied increasingly from 11% of IVF treatment cycles in 1995 to 55.6% in 2003. Fertilisation rates as high as 70% can be achieved with testicular sperm extraction (TESE) despite only using a few poor-quality sperm. The first clinical application of the procedure called preimplantation genetic diagnosis (PGD) was used in 1990 to prevent the transmission of two X-linked conditions: adrenoleukodystrophy and X-linked mental retardation

Better Freezing success with Vitrification

 Currently, each thawed oocyte has a mean survival rate of 47%, fertilisation rate of 52%, but pregnancy rate of only 1.52% . Other methods to circumvent oocyte damage caused by the freeze/thaw process include vitrification and cryopreservation of germinal vesicles. Vitrification uses high concentration of cryoprotectants to solidify the cell into a glass-like state without the formation of ice. Based on a small study, post-thaw survival rates and pregnancy rate of this approach were 68.8% and 21.4%,

Fertility Preservation is a breakthrough in IVF treatment

Ovarian tissue cryopreservation, achieved by biopsy and cryopreservation of ovarian cortex containing primordial follicles, followed by thawing and transplanting the autograft after completion of cancer treatment offers a potential solution in those circumstances. Transplantation can be either orthotopic (in close proximity to the infundibulo-pelvic ligament) or heterotopic (ie, forearm or abdomen). improving the efficiency of oocyte cryopreservation and of ovarian tissue transplantation promises to provide options to women who must delay childbearing.

 

 

Thyroid Hormone in Fertility and Pregnancy

Thyroid Hormone in Fertility and Pregnancy

 

Thyroid hormone  is produced by the thyroid gland present at the neck and is controlled by Thyroid Stimulating Hormone (TSH)  to produce more hormones when needed. Elevated TSH levels can be a sign that the thyroid gland is under-active. When thyroid function is not sufficient to meet, your body’s needs it is called hypothyroidism.

Hypothyroidism can lead to infertility, increased miscarriage risk, and complications in both mother and baby. 50 to 70% of hypothyroid female patients have menstrual abnormalities. Many present with oligo menorrhea (scanty bleeding during cycle). Severe hypothyroidism is commonly associated with failure of ovulation and infertility. Ovulation and conception can occur in mild hypothyroidism. But these pregnancies are at risk of abortions, stillbirths, or prematurity.

If you are trying to conceive then proper evaluation of thyroid hormone function is essential. In fact, thyroid tests are included in basic hormone tests for infertility.

 

What is subclinical hypothyroidism?

SCH is classically defined as a thyrotropin (TSH) level above the upper limit of normal range (4.5−5.0 mIU/L) with normal free thyroxine

(FT4) levels. Women with unexplained infertility more commonly present with this condition than women with infertility due to a known cause.

Should non-pregnant women be treated for SCH (subclinical Hypothyroidism)?

There is no benefit from the standpoint of lipid profile or alteration of cardiovascular risk in non-pregnant women. The risk of over-treatment with thyroid hormone can result in bone loss. Hence refrain from self-treatment with thyroid hormone and consult your doctor for proper advice.

How does your thyroid affect your pregnancy?

 TSH levels outside the normal pregnancy range are associated with an increased risk of pregnancy complications as placental abruption, preterm birth, foetal death, and preterm breaking of waters (premature rupture of membranes). If you are taking thyroid medications then you should continue the treatment during pregnancy. Regular tests will guide you to dosage adjustments in pregnancy.

Can you get pregnant if you have thyroid problems?

Unexplained infertility and ovulatory disorders can cause infertility in patients with low thyroid hormone levels. But you can still conceive with thyroid problem. In this scenario, you must consult you treating doctor for prevention of complications in pregnancy.

Can a thyroid problem cause a miscarriage?

Low thyroid hormone is associated with adverse reproductive outcomes. The problems include miscarriage, pregnancy complications, and delayed foetal neurodevelopment. There is fair evidence that thyroid autoimmunity (positive thyroid antibody) is associated with miscarriage and infertility. Treating TSH levels >4.0 mIU/L is associated with improved pregnancy and miscarriage rates.

What should be the thyroid level during pregnancy?

The Endocrine Society recommends the following pregnancy trimester guidelines for TSH levels: 2.5 mIU/L is the recommended upper limit of normal in the first trimester,

3.0 mIU/L in the second trimester, and 3.5 mIU/L in the third trimester.

 

Should there be universal screening for hypothyroidism in the first trimester of pregnancy?

The American College of Obstetricians and Gynaecologists does not recommend routine screening for hypothyroidism in pregnancy unless women

have risk factors for thyroid disease. During your pregnancy, a thyroid test may not be advised if you don’t have any symptoms or risk factors. But women

at high risk for thyroid disease should be screened.

Does thyroid affect pregnancy baby?

Untreated maternal hypothyroidism can cause delayed foetal neurologic development. Children delivered to mother with untreated hypothyroid may show impaired school performance, and lower intelligence quotient (IQ).

 Can thyroid cause birth defects?

Delayed foetal neurodevelopment can result from thyroid deficiency in pregnancy. Thyroid maternal under function, even when considered mild (or subclinical), may be associated with an impairment of brain development of the baby.

If you are taking thyroid hormone you will need regular checks to adjust dosage. You should not discontinue treatment without proper advice form physician. During pregnancy, you may have to alter the dosage. Regular pregnancy checks are required to prevent any complications in mother and baby.

 

Fertility Enhancing Surgeries

HEALTH TIPS

Surgeries that can Enhance Fertility

Surgeries that can enhance fertility

Fertility enhancing surgeries are usually advised to young women with suspected minimal to moderate disease of tubes, ovaries or uterus. These surgeries may enhance the rate of spontaneous pregnancy or IUI treatment. Usually such surgeries are done by experts through laparoscope to prevent damage to pelvic organs.

Fertility enhancing surgeries in female infertility

Myomectomy :

Uterine fibroids are the most common tumours in the female. Fibroids in infertile women undergoing assisted reproductive treatment can decrease success rates than do age-matched women with no fibroid. Removal of fibroids(myomectomy) can help these cases. However, myomectomy is restricted to women with unexplained infertility. If you have fibroids growing into the uterine cavity then you are more likely to benefit after myomectomy. Higher pregnancy rates can be achieved after laparoscopic removal than open surgery. This procedure can be considered if you are suffering from infertility for long years.

Tubal anastomosis:

Tubal sterilization is one of the most commonly used contraceptive methods worldwide. Approximately 1% of the women who undergo this procedure may request reversal of the procedure to restore fertility. However, if you are going for this procedure you must be aware of its cost benefit analysis. Due to its low success rate, often IVF is preferred to tubal anastomosis. Tubal anastomosis by the laparoscopic approach has the advantages over open surgery. Less postoperative discomfort and fewer complications, a smaller incisional scar, a shorter recovery time, and earlier resumption of normal activities are the advantages of laparoscopic procedure. This could be especially beneficial for a patient who previously has undergone a laparotomy or caesarean section because it allows her to avoid a second surgery.

Patient selection as well as meticulous surgical technique are key factors in achieving satisfactory pregnancy rates.

Excision of endometriosis:

In women with minimal and mild endometriosis, surgical removal or thermal destruction(ablation) of endometriosis is recommended as first line with higher success rate.

Laparoscopic surgery for destruction of mild endometriosis almost doubles the spontaneous pregnancy rate. IVF is the best option for patients after failed primary surgery. Repeat surgery is associated with lower pregnancy rate.

The pregnancy rate after intrauterine insemination IUI may be increased after surgery for mild endometriosis. The place of IUI is limited in patients with moderate or severe endometriosis and in older women. The incidence of recurrence of endometriosis is not increased after ovarian stimulation for IVF.

Ovarian cystectomy:

Ovarian cysts commonly are simple cysts(functional)or chocolate cysts (endometrioma).

Functional cysts, unless they become very large, these types of ovarian cysts don’t affect fertility. Hence your doctor may prefer to wait and watch for growth of these cysts. Small cysts may regress on their own.

Ovarian endometriomas are managed by laparoscopic procedures, like cyst aspiration or excision.

 Distal tubal disease and tubal reconstruction:

These procedures are of minimal benefit for fertility. At times these surgeries can be done for young patients with hydro salpinx who don’t want to go for IVF. Of all surgical treatments for tubal disease, sterilization reversal results in the highest pregnancy rates. The procedure is appealing to couples who desire an extended family or who are not comfortable with IVF. The ectopic pregnancy risk and the need for future contraception are recognized disadvantages with these procedures.

 Benefits of bariatric surgery for obesity:

 Obese men and women may benefit from weight loss programme or surgical removal of fat content from body.

Female Infertility

Polycystic ovary syndrome (PCOS) is the most frequent cause of female infertility. It is often associated with obesity. PCOS, hirsutism, and menstrual irregularities improve after bariatric surgery. The increased risk of miscarriage in obese women may decline after bariatric surgery.

Male infertility 

Obesity can be associated with reduced sperm concentrations. Weight loss is the cornerstone of the treatment of obesity-related infertility. It can restore fertility and normal hormonal profiles. But effects of bariatric surgery impact on male fertility is still unclear. At times sperm counts may be adversely affected by fat loss surgery.

Adhesiolysis :

Laparoscopic adhesiolysis still remains a useful and effective procedure for infertile couples with pelvic adhesions. These adhesions may be a result of previous surgery or infections like abdominal tuberculosis.

 Septal resection:

Although septate uterus does not seem to be an infertility factor hysteroscopic septum resection is accompanied by a significant improvement in the reproductive performance. There is no adverse effect in the achievement of pregnancy in women with a history of recurrent abortions after septum removal.

Hysteroscopic septum resection in women with septate uterus significantly improves the live birth rates and future fertility is also not impaired.

Metroplasty:

Metroplasty refers to repairing the womb with birth defects like extra horn, double uterus or divided uterus. Women with uterine partition(septum) and otherwise unexplained infertility might benefit from hysteroscopic metroplasty.

Ovarian drilling:

 Ovarian drilling is done in women with PCOS to break the thick outer surface and destroy some of the testosterone producing tissue made by the ovaries. This can help the ovaries release an egg each month and start regular monthly menstrual cycles. This may reduce symptoms of excess testosterone as well.

Uterine transplantation:

The uterine transplant is the surgical procedure whereby a healthy uterus is transplanted into an individual who does have one from birth or got it removed for disease process. Although it appears as a breakthrough procedure in the field of infertility its results are yet to be studied.

Surgery for Ectopic pregnancy:

Surgery for ectopic pregnancy usually involves the fallopian tubes. It is aimed at preserving the tubes for future fertility but recurrence of ectopic is common in such situations.

Fertility enhancing surgery in male infertility

 Varicocelectomy:

Varicocele is one among the most common causes of male infertility. The adverse effect of varicocele on spermatogenesis can be attributed to an increased testicular temperature. The results of varicocele surgery are not conclusive and not encouraging for restoring fertility. Hence this is reserved for people with severe grade of the disease. ICSI is an alternative method of fertility treatment in these patients.

TESA, PESA, MESA & Testicularbiopsy:

These are procedures of sperm retrieval for patients undergoing ICSI treatment. Usually these procedures are advised in patients with azoospermia with blockage of the passage (vas deferens).

Reversal of vasectomy:

Vasectomy reversal is surgery to undo a vasectomy. Success rates with vasectomy reversal will range from about 40 percent to over 90 percent. In some cases, pregnancy, still may not happen after a vasectomy reversal, even when there is sperm. This may be due to decreased motility of sperm.

HSG test for infertility – Advantages and Side effects

HSG test for infertility – Advantages and Side effects

Why HSG (Hysterosalpingogram) is done?

Hysterosalpingogram ( HSG) is a type of X-Ray of abdomen to know the condition of the fallopian tubes. If the fallopian tubes are blocked then couple may have difficult in conceiving, it is required to check whether tubes are open or not in cases of infertility. It’s also used to investigate miscarriages resulting from abnormalities within the uterus such as tumour masses, adhesions and uterine fibroids.

What is HSG

What is HSG

 What is a Hysterosalpingogram (HSG)?

HSG is a diagnostic X-Ray procedure that usually takes around 15 minutes to perform. It is usually done before ovulation around 10 -12 days after menstruation. This is done on an outpatient basis.

How the patient is prepared for HSG?

The doctor usually obtains history regarding pregnancy and any allergies as HSG should not be done on a pregnant woman. Any kind of allergies should be noted as the dye used in this procedure may cause severe reactions in such people. This procedure should not be performed in inflammatory condition like chronic pelvic infection or an untreated sexually transmitted disease. Since the dye used may damage a developing foetus doctors advise to take contraceptive pills in the cycle when HSG is done in order to prevent pregnancy. The patient is also given antibiotics to prevent infection and also at times a pain killer to reduce the discomfort during the procedure.

 

How is a Hysterosalpingogram done?

Hysterosalpingography uses a real-time form of x-ray called fluoroscopy to examine the uterus and fallopian tubes

A woman is positioned under a fluoroscope (an x-ray imager that can take pictures during the study) on a table. The doctor then examines the patient’s uterus and places a speculum in her vagina. Her cervix is cleaned, and a cannula is placed into the opening of the cervix. A liquid containing iodine (a fluid that can be seen by x-ray) is slowly pushed through the cannula. The contrast is seen as white on the image and can show the contour of the uterus as the liquid travels from the cannula, into the uterus, and through the fallopian tubes. If the tubes are blocked the dye doesn’t pass through and may cause swelling of the tubes called hydrosalpinx.

After the HSG, a woman can immediately return to normal activities but refrain from intercourse for a few days.

Does HSG cause pain?

An HSG usually causes mild or moderate cramping pain for about an hour. However, some women may experience cramps for several hours. These symptoms can be greatly reduced by taking medications used for menstrual cramps like pain killers before the procedure or when they occur.

What are the risks of HSG?

HSG is considered a relatively safe procedure. However, some complications mild or serious can happen in less than 1% of the time. There is always a slight chance of cancer from excessive exposure to radiation. However, the benefit of an accurate diagnosis far outweighs the risk. The effective radiation dose for this procedure varies. Special care is taken during x-ray examinations to use the lowest radiation dose possible while producing the best images for evaluation.

In the event of a chronic inflammatory condition, pelvic infection or untreated sexually transmitted disease, be certain to notify the physician or technologist before the procedure to avoid worsening of infection.

Women should always inform their physician or x-ray technologist if there is any possibility that they are pregnant.

 

  1. The most common serious problem with HSG is pelvic infection. This usually occurs when a woman has had previous tubal disease (such as a past infection of chlamydia). In rare cases, infection can damage the fallopian tubes or make it necessary to remove them. A woman should call her doctor if she experiences increasing pain or a fever within 1-2 days of the HSG.

 

  1. Fainting – Rarely, some woman may get light-headed during or shortly after the procedure and faint due to a vasovagal attack.

 

  1. Iodine Allergy – Rarely, a woman may have an allergy to the iodine contrast used in HSG. A woman should inform her doctor if she is allergic to iodine, intravenous contrast dyes, or seafood. Women who are allergic to iodine should have the HSG procedure performed without an iodine-containing contrast solution. If a woman experiences a rash, itching, or swelling after the procedure, she should contact her doctor.

 

  1. Spotting – Spotting sometimes occurs for 1-2 days after HSG. Unless instructed otherwise, a woman should notify her doctor if she experiences heavy bleeding after HSG.

What are the limitations of HSG?

Hysterosalpingography only sees the inside of the uterus and fallopian tubes. Abnormalities of the ovaries, wall of the uterus, and other pelvic structures may be evaluated with MRI or ultrasound. Alternatively, a surgical procedure to directly view the tubes (laparoscopy) can be done which is more accurate than HSG.

What is the next step if tubes are found to be blocked on HSG?

Patients may undergo revaluation of tubes with laparoscopy or may be suggested to go for IVF. In vitro fertilization (IVF) is a procedure which can bypass the function of the tubes and can achieve pregnancy in cases with the blocked fallopian tubes.
