Letrozole Versus Letrozole and Inositol

Polycystic ovary syndrome (PCOS) is one of the most common endocrine and metabolic disorders affecting women of reproductive age. Its prevalence varies considerably according to the population studied and the diagnostic criteria applied. A recent global systematic review and meta-analysis estimated the prevalence of PCOS among adult women to be approximately 12.1% according to the Rotterdam criteria, compared with 7.9% using the National Institutes of Health (NIH) criteria and 12.7% using the Androgen Excess-PCOS Society criteria.
