Clomiphene for Infertility

- Perform a clomiphene challenge test, which is sometimes used to evaluate a woman's ovulation and egg quality (Reference ovarian reserve). When given early in a woman's menstrual cycle for 5 days, clomiphene elevates a woman's follicle-stimulating hormone (FSH) level. On the next day, an FSH blood level that has dropped back to normal is a sign of a normal ovarian reserve and ovulation. An elevated FSH is a sign of low ovarian reserve. Women who have a diminished ovarian reserve can use donor eggs, which greatly improves their chances of giving birth to a healthy child.
- Stimulate the development of multiple eggs for use with Reference assisted reproductive technology Opens New Window, such as in vitro fertilization (IVF) or gamete intrafallopian transfer (GIFT).
- Regulate ovulation in a woman who ovulates irregularly and/or is going to have Reference intrauterine insemination or artificial insemination Opens New Window.
