As kids, we all learned about the birds and the bees. But we probably didn’t learn enough about fertility to know how babies can be conceived when nature doesn’t work perfectly.
Here, then, the 411 on in vitro fertilization.
You’ve probably read the acronym “IVF” hundreds of times in magazines and newspapers, heard it on the news, and maybe even had a friend or relative who was able to get pregnant using this technology. You probably know the initials stand for “in vitro fertilization,” and that the media sometimes calls the children born after IVF, “test tube babies.” But how many people, apart from medical doctors (and women who’ve actually tried IVF) know what’s really involved in this fertility technology?
What is IVF?
IVF, or “in vitro fertilization,” involves several steps. First, a woman is given fertility drugs that stimulate her ovaries to produce as many mature eggs as possible (instead of the usual one per monthly cycle). Second, the eggs are retrieved using a suction needle inserted into the ovary. Third, the eggs are fertilized by combining them with sperm in a culture dish. Finally, the best-quality embryos are transferred into a woman’s uterus. If all goes well, a normal pregnancy is the result.
Who is IVF for?
IVF can be used to help couples with a variety of fertility challenges—male and female—to get pregnant. As with natural conception, success rates are higher in younger women (generally meaning under 40). There are many criteria for determining who might benefit from IVF, and couples need to consult with a fertility specialist before determining whether IVF can help them get pregnant and achieve their families. Rather than looking at IVF as a last resort, think of it as “the ultimate treatment,” suggests Arthur L. Wisot, M.D., executive director of Reproductive Partners Medical Group in Southern California and co-author of Conceptions and Misconceptions (Hartley & Marks, 2004).
What’s the First Step in IVF?
After an examination, a doctor will devise a fertility “protocol” (a plan for the course of medical treatment) for a woman, highlighting all of her recommended fertility “to-do’s,” such as medications and blood tests. It’s important that a woman follow this protocol carefully, even if the directions don’t seem to make sense. For instance, many doctors will prescribe birth control pills for the first two months, since the hormones in oral contraceptives can help the ovaries to produce quality eggs when they’re needed later. The Pill can also help regulate the menstrual cycle, so the doctor knows what’s happening at what time, and when would be the best time to begin the IVF cycle.
