ovulation induction
Medical treatment using medications to stimulate ovulation in women with ovulatory disorders.
Full Definition
Ovulation induction is a fertility treatment that uses various medications to stimulate the development and release of eggs in women who have irregular or absent ovulation. The most common indication is polycystic ovary syndrome (PCOS), but it's also used for other ovulatory disorders and unexplained infertility. First-line treatment typically begins with oral medications such as clomiphene citrate or letrozole, which block estrogen receptors or inhibit aromatase enzyme, respectively, leading to increased FSH release. If oral agents fail, injectable gonadotropins may be used, requiring careful monitoring to prevent multiple pregnancy and ovarian hyperstimulation syndrome. Treatment cycles involve regular monitoring with ultrasound and hormone levels to track follicular development and time ovulation triggering or intercourse.
Usage
Usage note: Distinguish from controlled ovarian stimulation (used for IVF to produce multiple eggs).
