What medications are used for ovulation induction?

Women experiencing ovulatory dysfunction may be treated with ovulation-inducing medications. Ovulation-inducing drugs are agents that help increase the number of ovulations and are commonly used to assist women who cannot conceive due to anovulation caused by menstrual irregularities. So, which medications are used for ovulation induction? Below is a detailed explanation.

Which Medications Are Used for Ovulation Induction?

Commonly prescribed ovulation-inducing medications include clomiphene citrate, letrozole, human chorionic gonadotropin (hCG), human menopausal gonadotropin (hMG), and gonadotropin-releasing hormone (GnRH). Additionally, certain traditional Chinese medicines (TCMs) can promote follicular development and support ovulation to some extent—for example, Tiaojing Cuyun Wan (Regulating Menstruation and Promoting Pregnancy Pills), Kunling Wan (Kunling Pills), Dingkun Dan (Dingkun Pills), and Jinfeng Wan (Jinfeng Pills). These TCM formulations have demonstrated clinical efficacy in promoting follicular growth. Although these medications generally have few major contraindications, it is essential to consult a qualified healthcare provider at a reputable medical institution for proper diagnosis and personalized treatment planning before initiating any ovulation-inducing therapy. Two critical considerations during ovulation induction are: (1) avoiding ovarian hyperstimulation syndrome (OHSS) and (2) preventing premature ovarian insufficiency (POI). Concurrently, dietary modifications—such as increasing intake of whole grains and soy-based foods like soy milk and black beans—may be beneficial, as these contain high levels of phytoestrogens that support follicular development.

Knowledge Extension: Side Effects of Ovulation-Inducing Medications

1. Accelerated Onset of Menopause

The total number of ovarian follicles is finite. Prolonged use of ovulation-inducing agents to accelerate follicular maturation inevitably leads to rapid depletion of the approximately 40,000 primordial follicles present at puberty. Once all follicles are exhausted, estrogen production ceases, triggering the onset of menopause.

2. Elevated Estrogen Levels

Ovulation-inducing medications disrupt the negative feedback of estrogen on the hypothalamus, resulting in persistently elevated systemic estrogen levels. This may precipitate ovarian hyperstimulation syndrome (OHSS), characterized by endocrine imbalance, electrolyte and fluid disturbances, pelvic/abdominal ascites, and even thromboembolic events. Chronically elevated estrogen levels may also accelerate the growth of breast tumors and ovarian cysts.
