What is In Vitro Fertilization (IVF)?
IVF is a process in which eggs are removed from the ovary and fertilized in a special laboratory. The eggs will grow and divide within themselves for three to five days. The resulting embryo will then be transferred into the uterus.
After retrieval of the mature eggs, the eggs are mixed with the sperm in a special culture medium or by ICSI (Intra-cystoplasmic sperm injection) procedure and incubated for 24 hours. The eggs are then examined under a microscope for signs of fertilization. Usually 60 – 75% of eggs are fertilized.
When the eggs divide and grow they are called embryos. After 3 days, if the embryos are growing normally, they are ready to transfer. Embryos are usually transferred on day 3 or day 5 (blastocyst transfer) after being fertilized.
IVF may be an option for women who have blocked or absent fallopian tubes, ovulation disorders, endometriosis, unexplained infertility, or have male factor problems.
