Ovulation Induction

Ovulation induction is a fertility treatment that involves the use of medication to stimulate the ovaries to produce and release eggs. It is used in people who have difficulty ovulating due to polycystic ovary syndrome (PCOS), or for couples with unexplained infertility to increase the chances of conception. The medications used in ovulation induction include clomiphene citrate, letrozole, or injectable gonadotropins. The goal of ovulation induction is to cause follicle maturation and the release of one or more eggs from the ovaries. Pelvic ultrasound and blood tests are often used to measure a person’s response to the medications and to time intercourse or other procedures such as intrauterine insemination (IUI). In order for ovulation induction cycles to be successful, the fallopian tubes must be patent and functioning. Sperm parameters should also be relatively normal. Ovulation induction is often attempted for 3 consecutive months before considering more invasive treatments such as in vitro fertilization. The pregnancy rates depend on age, but range from 5-20% per month of treatment.
