Assisted reproductive technologies — There are several variations of these high-tech methods in which sperm and egg are combined to maximize the chances of achieving a successful pregnancy. All of the variations involve two steps — beginning with the woman taking fertility drugs to stimulate the ovaries to produce several eggs (superovulation); followed by the use of procedures to retrieve them, while she is under anesthesia. The best known of these methods is in-vitro fertilization (IVF), which was responsible for the birth of many "test-tube babies." The eggs obtained through the vaginal canal using ultrasound guidance are fertilized with the partner's sperm outside the woman's body, not in a test tube, but in a culture dish. A few days later, the eggs, now called zygotes, are placed in the woman's uterus. If one or more of the zygotes implants successfully, pregnancy results. One study reported that 17% of women who have this procedure once go on to deliver a baby. Two variations of this technique are gamete intra-fallopian transfer (GIFT), and zygote intra-fallopian transfer (ZIFT). Using GIFT, the harvested eggs are mixed with the man's sperm and then inserted directly into the fallopian tubes, which allows fertilization (if it occurs) to take place in the natural way. In ZIFT, the harvested eggs are fertilized in a culture dish and then placed in the fallopian tubes during laparoscopic surgery. Both of these methods are only suitable for women who have functional fallopian tubes. The national rate for successful deliveries for one pregnancy attempt using these methods are 27% for GIFT and 23% for ZIFT. When selecting a clinic, you should check on its success rate.
