Ovulation induction: a mini review.

Area of Science:

• Reproductive Endocrinology
• Infertility Treatment
• Gynecology

Background:

• Anovulatory infertility affects women's reproductive health.
• Polycystic ovary syndrome (PCOS) is a common cause of anovulation.
• Effective ovulation induction is crucial for fertility treatment.

Purpose of the Study:

• To review current ovulation induction methods for anovulatory infertility and PCOS.
• To compare the effectiveness and outcomes of different treatment modalities.
• To highlight first-line and alternative therapies for specific patient populations.

Main Methods:

• Review of established and emerging treatments for ovulation induction.
• Discussion of hormonal therapies (FSH, LH, HCG, GnRH).
• Evaluation of pharmacological agents (clomiphene citrate, aromatase inhibitors, insulin sensitizers) and surgical options (ovarian drilling).

Main Results:

• For hypogonadotrophic hypogonadism, FSH and LH with HCG are used; pulsatile GnRH is an effective alternative with lower multiple pregnancy rates.
• Clomiphene citrate is the primary treatment for PCOS, achieving high pregnancy rates in selected patients.
• Low-dose FSH is a second-line therapy for PCOS, promoting monofollicular development; laparoscopic ovarian drilling is an alternative for clomiphene-resistant cases.

Conclusions:

• Treatment selection for ovulation induction depends on the underlying cause of infertility (e.g., hypogonadotrophic hypogonadism vs. PCOS).
• Lifestyle modifications (weight loss, exercise) are crucial for obese women with PCOS.
• While established treatments are effective, ongoing research explores newer agents like aromatase inhibitors and insulin sensitizers.
