Today, in vitro fertilization (IVF) is a commonly used word. Louise Brown, born in England in 1978, was the first such baby to be conceived outside her mother's womb. IVF is a procedure which involves combining eggs and sperm outside the body in a laboratory and once an embryo or embryos form, they are then placed in the uterus. Even though IVF is a complex and expensive procedure, it is a boon for the childless couple hoping and praying for a baby. Since its introduction in the U.S. in 1981, IVF and other similar techniques have resulted in more than 200,000 babies. IVF may be an option if you have been diagnosed with endometriosis, problems with the uterus or fallopian tubes, problems with ovulation, antibody problems that harm your eggs. It may also be because of your partner’s low sperm counts, the inability of sperm to penetrate or survive in the cervical mucus or it could be just unexplained .IVF is never the first step in the treatment of infertility. Instead, it's reserved for cases in which other methods such as fertility drugs, surgery, and artificial insemination haven't worked. One should carefully assess any treatment center before undergoing the procedure. You can check about the pregnancy ratio per embryo transfer, pregnancy rate for couples in your age group and with similar fertility problem, live birth rate for all couples who undergo this procedure each year at the facility, how many of those deliveries are twins or other multiple births, how much will the procedure cost, including the cost of the hormone treatments and the cost to store embryos and how long can you store them. Any embryos that you do not use in your first IVF attempt can be frozen for later use. This will save you money if you undergo IVF a second or third time. If you do not want your leftover embryos, you may donate them to another infertile couple, or you and your partner can ask the clinic to destroy the embryos.
