Abstract
This study investigates how semen parameters, endometrial thickness, and hormonal profile affect outcomes in unexplained infertility cases undergoing intrauterine insemination (IUI) with two letrozole protocols: step-up and fixed-dose regimens. An analysis of clinical, biochemical, and sonographic markers was performed in relation to ovulation, follicular development, endometrial lining, and pregnancy rates.
