This systematic review and meta-analysis evaluated the efficacy of the stair-step protocol (SSP) versus the traditional clomiphene citrate protocol for ovulation induction in women with polycystic ovary syndrome (PCOS). Analyzing data from five randomized controlled trials involving 520 participants, the SSP was found to significantly increase ovulation rates (RR 1.28) and reduce treatment duration by an average of 32.59 days, while not affecting endometrial thickness.
Key findings
- SSP increased ovulation rates compared to the traditional protocol (RR 1.28).
- Clinical pregnancy rates favored SSP (RR 1.46), though driven by one study.
- SSP shortened treatment duration by an average of 32.59 days.
- Endometrial thickness was similar between both protocols.
Why it matters
Understanding the comparative effectiveness of ovulation induction protocols is crucial for optimizing treatment strategies in women with PCOS, potentially leading to improved reproductive outcomes and reduced treatment burden.
