What is IVF?
IVF (In-vitro fertilization) or test tube baby as it is commonly called is a procedure in which the eggs and the sperms are fertilized outside the body and then transferred back to the womb after 2-5 days.
Who needs an IVF?
IVF may be considered if,
- you have been diagnosed with unexplained infertility
- your fallopian tubes are blockedother techniques such as fertility drugs or intrauterine insemination (IUI) have not been successful
- other techniques such as fertility drugs or intrauterine insemination (IUI) have not been successfulthe male partner has fertility problems and an abnormal semen analysis
- The male partner has fertility problems and an abnormal semen analysis
- you are using your partner’s frozen sperm in your treatment and IUI is not suitable for you
- you are using donated eggs or your own frozen eggs in your treatment
- you are using embryo testing to avoid passing on a genetic condition to your child.
- If you have severe endometriosis
What do I expect during my treatment cycle?
Your treatment cycle would be as follows
Step 1: Once you have decided to go ahead with IVF, you will undergo a day care procedure called hysteroscopy to assess the suitability of the uterus to hold the baby. It is generally done one month before your IVF cycle and involves the introduction of a small camera into the womb through the vagina to visualize the inside of the uterus. You will be given anaesthesia during the procedure and hence there will be no pain.
Step 2: Your husband has to freeze one semen sample as a back up.
Step 3: Typically your treatment would begin on the second or third day of periods. It involves a scan and hormone tests followed by daily injections for about 8-10 days, along with monitoring by scan and hormone tests in between. Once the eggs are sufficiently grown as per the scan and hormone tests, you will receive injection Hcg as a ovulation trigger.
Step 4: Egg retrieval is performed transvaginally 35 – 36 hours later, with light anaesthesia, using a transvaginal ultrasound guidance. You will be discharged same evening, unless there are problems associated with bleeding, undue pain or ovarian hyperstimulation.
Step 5: After retrieval, eggs are assessed for their maturity. Meanwhile husband has to give a fresh semen sample. Mature eggs are injected with the sperms on the same day and grown in the incubator for 3-5 days.
Step 6: The final step is the embryo transfer. 3-5 days after your egg retrieval, two or three embryos are selected and gently transferred into the womb using an abdominal ultrasound guidance. The procedure is usually painless, no anaesthesia is required and you will be discharged in about two to three hours.
Step 7: You will be given certain supportive medications starting from the day of egg retrieval till your pregnancy check. You will be called for a pregnancy check 16-17 days after your embryo transfer.
What precautions do I take during the IVF treatment?
- Eat a healthy diet rich in fruits and vegetables
- Be stress free and relax your mind
- Avoid intercourse during the treatment.
- Don’t do strenuous job during the treatment as your ovaries are enlarged and they may twist sometimes causing acute pain.
How do I prepare myself for an egg retrieval procedure?
You will get admitted to the hospital early in the morning, between 6am – 7am and you have to be empty stomach atleast 6-8 hours before the procedure. You will be administered light anaesthesia as intravenous medication. The procedure is done vaginally using the scan guidance and a small needle. The entire procedure takes about 20-30 minutes. Post procedure you may have slight pain or bleeding which usually subsides with medication. You will be discharged about 6 hours later.
What do I expect during embryo transfer?
It is done 3-5 days following the egg retrieval, which will be decided by your clinician. No anaesthesia is required as it is a painless procedure. Rarely during your initial assessment if it is found that getting into the uterus is difficult or if you are very uncooperative, you may be given light anaesthesia. Your bladder has to be full before the procedure as it is done under abdominal scan guidance. Do not wear perfume/ deodorant or powder on that day as they are harmful to the embryos. Two or Three embryos are gently transferred to the uterus using a small catheter. You will lie down for about 15 – 30 minutes after the procedure and later you can pass urine. No need to take bedrest until your pregnancy check. This does not increase your chances of becoming pregnant.
What is ICSI? How does it differ from IVF?
ICSI – Intracytoplasmic sperm injection, is an IVF procedure in which a single sperm is injected directly into an egg whereas in IVF, about 50,000 to 1,00,000 sperms are inseminated around the eggs and one of them penetrates the egg on its own. ICSI increases the fertilization rates especially in male factor infertility and cases of previous fertilization failure.
What is the success rate?
Success rate varies with multiple factors especially the age of the women, egg and the sperm quality and the underlying cause of infertility. Over all the success varies between 40-50 %. Success decreases as the age of the woman increases.
What is frozen embryo transfer?
Surplus embryos after your transfer can be frozen and kept in liquid nitrogen at -180 degree Celsius, for later use.
What are the complications?
Two most important complications of IVF are
- Multiple pregnancy (20-25%)
- Ovarian hyperstimulation syndrome which occurs due to excessive response and can be prevented b appropriate modifications in the medications
- Rarely ovaries may twist causing acute pain and may require a laparoscopy
When can I know if I have become pregnant?
You will be tested for beta HCG – a blood test to confirm pregnancy 14 to 16 days after your embryo transfer
Is my pregnancy going to be more riskier after IVF?
There is no evidence to show that IVF babies have increased rate of abnormalities. The pregnancy outcome will be like a normal conception but your doctor may have a low threshold for intervention when the problem arises.
