Summary
Polycystic ovary syndrome (PCOS) treatment lacks a clear ovulation induction algorithm. Weight loss, clomiphene citrate, and gonadotropins are common, but insulin sensitizers and surgery have limited roles for PCOS-related infertility.
Area of Science:
- Reproductive Endocrinology
- Infertility Management
Background:
- Polycystic ovary syndrome (PCOS) is a leading cause of anovulatory infertility.
- Current ovulation induction strategies for PCOS lack an evidence-based decision-making algorithm.
Purpose of the Study:
- To review and synthesize current evidence on ovulation induction methods for PCOS.
- To discuss the efficacy and risks of various ovulation induction approaches in PCOS patients.
Main Methods:
- Review of existing literature on ovulation induction in PCOS.
- Analysis of first-line therapies (clomiphene citrate), second-line options (gonadotropins), and adjunctive treatments (insulin sensitizers, surgery).
Main Results:
- Weight loss is recommended for obese PCOS patients. Clomiphene citrate is the first-line medical therapy.
- Parenteral gonadotropins are used for clomiphene-resistant cases but carry risks of multiple pregnancy and OHSS.
- Insulin sensitizers show modest ovulation improvement, and surgical diathermy is a reserved option for specific cases.
Conclusions:
- An evidence-based algorithm for PCOS ovulation induction is needed.
- Treatment choice should consider patient characteristics, response to prior therapies, and associated risks.
