Experience in optimizing fertility outcomes in men with congenital adrenal hyperplasia due to 21 hydroxylase deficiency.

Objective: Men with congenital adrenal hyperplasia (CAH) have impaired fertility. We aimed to assess fertility outcomes and the importance of hypogonadotropic hypogonadism, testicular failure and the presence of testicular adrenal rest tumours (TART).

Design: Retrospective analysis of men attending an adult CAH clinic in a tertiary centre.
