An Evaluation of Letrozole and Clomiphene Citrate Efficacy as Ovulation Induction Medication in Females with Polycystic Ovarian Condition
Abstract: Polycystic ovarian condition is the most common endocrinopathy in anovulatory infertile females. As a long-established conventional treatment for ovulation induction, clomifene citrate (also known as clomiphene) is still recommended to PCOS patients as their first line of treatment. Indian PCOS women are more prone to have high levels of clomiphene resistance due to the high frequency of insulin resistance . While letrozole has a high potential for ovulation induction, it …
