Assisted Reproductive Technologies: If a cause for infertility is identified, the clinical care provider may suggest a specific treatment. However, sometimes no specific problem is found, and the infertility is labeled as “unexplained.” With unexplained infertility, or when traditional treatments have failed, advanced infertility therapies such as super ovulation with timed intrauterine insemination (SO/IUI) or in vitro fertilization (IVF) may be suggested. In an SO/IUI cycle, fertility medications are administered to start the growth of multiple eggs in the ovaries. When these eggs are ready to ovulate, the partner’s washed sperm is placed directly into a woman’s uterus. This procedure is called intrauterine insemination (IUI) and causes minimal discomfort. IVF involves removing the eggs and fertilizing them with the male partner’s sperm in the laboratory and then transferring the resulting embryos to the uterus. Either procedure, as well as any infertility treatment, may be used with donor sperm rather than sperm from the woman’s partner. With any treatment, a woman’s age affects the chance for pregnancy. In women over 40, the success rate of SO/IUI is generally less than 5% per cycle. This compares to success rates around 10% for women ages 35 to 40. IVF is more effective but also has relatively low success rates in women 40 and older, generally less than 20% per cycle.
