Abstract
PURPOSE: To determine if sildenafil improves endometrial thickness better than vaginal estradiol (E2) in women with a history of thin endometria. METHODS:Women failing to attain an 8 mm endometrial thickness on either the oocyte retrieval cycle or their first frozen embryo transfer (ET) despite an oral graduated E2 regimen were treated again with graduated oral E2 and were also randomly assigned to vaginal sildenafil or vaginal E2 therapy. Endometrial thickness was compared between the groups. RESULTS: Neither vaginal E2 nor sildenafil significantly improved endometrial thickness or blood flow in the subsequent frozen ET-cycle. CONCLUSIONS: These data fail to corroborate previous claims that 25 mg sildenafil four times daily intravaginally can improve endometrial thickness.
