For infertile patients with Polycystic Ovary Syndrome (PCOS) resistant to clomiphene citrate (CC) therapy, low-dose gonadotropin treatment offers similar efficacy with fewer complications. Identifying non-responders early can improve outcomes.

Area of Science:

  • Reproductive Endocrinology
  • Infertility Treatment
  • Polycystic Ovary Syndrome (PCOS)

Background:

  • Clomiphene citrate (CC) is a first-line treatment for anovulatory infertility, particularly in patients with PCOS.
  • A subset of patients with PCOS are resistant to CC therapy, necessitating alternative treatment strategies.
  • Predicting CC resistance and optimizing subsequent gonadotropin therapy is crucial for improving live birth rates and reducing treatment burdens.

Purpose of the Study:

  • To investigate the efficacy and safety of gonadotropin therapy in patients with PCOS who are resistant to CC therapy.
  • To compare low-dose gonadotropin protocols with conventional regimens in terms of efficacy and complication rates.
  • To explore clinical characteristics that may predict CC resistance and guide individualized ovulation induction therapy.

Main Methods:

  • Retrospective analysis of infertile patients with PCOS undergoing ovulation induction.
  • Comparison of outcomes between patients treated with CC alone, CC followed by gonadotropins, and gonadotropins alone.
  • Evaluation of different gonadotropin dosing protocols (low-dose vs. conventional).
  • Assessment of clinical parameters and patient characteristics to identify predictors of treatment response.

Main Results:

  • Patients with PCOS resistant to CC therapy may respond differently to gonadotropin therapy.
  • Low-dose gonadotropin protocols demonstrate comparable efficacy to conventional regimens in achieving ovulation and pregnancy.
  • Low-dose gonadotropin protocols are associated with reduced rates of complications such as ovarian hyperstimulation syndrome (OHSS) and multiple pregnancies.
  • PCOS is a heterogeneous condition, and patient classification may influence treatment outcomes.

Conclusions:

  • For infertile patients with PCOS resistant to CC therapy, low-dose gonadotropin treatment is a viable and safer alternative.
  • Early identification of CC non-responders can facilitate timely initiation of gonadotropin therapy, potentially improving health and economic benefits.
  • Individualized treatment approaches, guided by predictive markers of ovarian responsiveness, are essential for optimizing ovulation induction and minimizing risks.
