New hope for PCOS: extended letrozole or adding inositol may help ovulation

NCT ID NCT07635082

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested two approaches to help women with PCOS who did not ovulate after standard letrozole treatment. One group took letrozole for 7 days instead of 5, and the other took letrozole plus inositol. The goal was to see which method led to more ovulations and pregnancies. The trial involved 200 women aged 18-35 with a BMI of 30 or less.
