In-vitro fertilization is a fertility technique where eggs are surgically removed from the ovaries after the mother is given fertility drugs and then are exposed to the husband's semen in a culture dish. The fertilized eggs are then implanted in the uterus of a woman during normal ovulation with the hope they will implant and come to term. However, the success rate for the procedure is usually no better than 50% and the procedure is also expensive. In-vitro is usually used when a couple is having trouble conceiving a child due to defects in the path between the ovaries and the uterus.
