When it comes to infertility, IVF may be an option if you or your partner have been diagnosed with:
- Low sperm counts
- Problems with the uterus or fallopian tubes
- Problems with ovulation
- Antibody problems that harm sperm or eggs
- The inability of sperm to penetrate or survive in the cervical mucus
- An unexplained fertility problem
IVF (“In Vitro Fertilization”)
IVF literally means ‘fertilisation in glass’. It is the most advanced procedure in the Assisted reproductive technology (ART ), where an egg is combined with sperm outside the body, in vitro (in glass). The process involves monitoring and stimulating a woman’s ovulatory process, removing an ovum (egg ) from the woman’s ovaries and letting the sperm fertilise them in a liquid in a laboratory. The fertilised egg (zygote) undergoes embryo culture for 2–6 days, and is then transferred into the woman’s uterus.
IVF is never the first step in the treatment of infertility except in cases of complete tubal blockage. Instead, it’s reserved for cases in which other methods such as fertility drugs, surgery, and artificial insemination haven’t worked.
What Can I Expect From IVF?
The first step in IVF involves injecting hormones so you produce multiple eggs each month instead of only one.You will then be tested to determine whether you are ready for egg retrieval.
Prior to the retrieval procedure, you will be given injections of a medication that ripens the developing eggs and starts the process of ovulation. Timing is important; the eggs must be retrieved just before they emerge from the follicles in the ovaries. If the eggs are taken out too early or too late, they won’t develop normally.
Your doctor may do blood tests or an ultrasound to be sure the eggs are at the right stage of development before retrieving them. The IVF facility will provide you with special instructions to follow the night before and the day of the procedure. Most women are given pain medication and the choice of being mildly sedated or going under full anaesthesia.
During the procedure, your doctor will locate follicles in the ovary with ultrasound and remove the eggs with a hollow needle. The procedure usually takes less than 30 minutes, but may take up to an hour.
Immediately following the retrieval, your eggs will be mixed in the laboratory with your partner’s sperm, which he will have donated on the same day.
While you and your partner go home, the fertilised eggs are kept in the clinic under observation to ensure optimal growth. Depending on the clinic, you may even wait up to five days until the embryo reaches a more advanced blastocyst stage.
Once the embryos are ready, you will return to the IVF facility so doctors can transfer one or more into your uterus. This procedure is quicker and easier than the retrieval of the egg. The doctor will insert a flexible tube called a catheter through your vagina and cervix and into your uterus, where the embryos will be deposited. To increase the chances of pregnancy, most IVF experts recommend transferring up to three embryos at a time. However, this means you could have a multiple pregnancy, which can increase the health risks for both you and the babies.
Following the procedure, you would typically stay in bed for several hours and be discharged four to six hours later. Your doctor will probably perform a pregnancy test on you about two weeks after the embryo transfer.
