In Vitro Fertilization (IVF) Treatment in India
In vitro fertilization (IVF) is a process of fertilization where an egg is combined with sperm outside the body, in vitro. The process involves monitoring and stimulating a woman’s ovulatory process, removing an ovum or ova (egg or eggs) from the woman’s ovaries and letting sperm fertilize them in a liquid in a laboratory. After the fertilized egg (zygote) undergoes embryo culture for 2–6 days, it is implanted in the same or another woman’s uterus, in a procedure called embryo transfer.
IVF is a type of assisted reproductive technology (ART) commonly referred to as fertility treatment. It is generally used as a fertility treatment for women with ovulation disorders, uterine abnormalities, or blocked or damaged fallopian tubes, or for men with sperm abnormalities.
Types of IVF
The two main types of IVF are:
- Natural cycle IVF: This involves harvesting a single mature egg during a woman’s natural ovulation cycle. This egg is then fertilized with sperm in a lab and the resulting embryo is transferred back into the woman’s uterus.
- Stimulated cycle IVF: This involves stimulating the ovaries to produce multiple eggs. The eggs are then retrieved and fertilized with sperm in a lab. The resulting embryos are transferred back into the woman’s uterus.
The IVF process typically involves the following steps:
- Ovulation induction: Medications are given to the woman to stimulate the ovaries to produce multiple eggs.
- Egg retrieval: The eggs are retrieved from the ovaries using a needle.
- Fertilization: The eggs are fertilized with sperm in a lab.
- Embryo transfer: The embryos are transferred to the woman’s uterus.
- Pregnancy test: A pregnancy test is done two weeks after the embryo transfer.
The success rates of IVF depend on a number of factors, such as the age of the woman, the cause of infertility, and the number of embryos transferred. The overall success rate of IVF is about 40%.
