Combined Letrozole-metformin-pioglitazone Versus Combined Clomiphene Citrate-metformin-pioglitazone in Clomiphene Citrate-resistant Women With Polycystic Ovary Syndrome
Abstract
Polycystic ovary syndrome (PCOS) affects 5-10% of women in childbearing age. Hyperinsulinemia contributes to chronic anovulation commonly encountered in women with PCOS. The first choice therapy is clomiphene citrate (CC). In CC resistant cases, the American College of Obstetrics and Gynecology (ACOG) recommends the use of insulin sensitizer metformin. Other insulin sensitizing agents include rosiglitazone and pioglitazone. Pioglitazone is said to improve fertility and ovulation in patients with PCOS.CC may be associated with poor endometrial thickening due to its antiestrogenic effect. Letrozole may improve this condition. In this study we will compare the effect of combined letrozole-metformin-pioglitazone with that of combined CC-metformin-pioglitazone in ovulation induction in CC-resistant PCOS women.
Conditions: Polycystic Ovary Syndrome, Infertility.
Primary outcome: Ovulation Rate.
Enrollment: 100 participants.
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 100 participants or records.
