'What should I do with a 60-year old man with a slightly low serum total testosterone concentration and normal levels of serum gonadotrophins'?

abstract：OBJECTIVE:Congenital adrenal hyperplasia (CAH) is an autosomal recessive inherited disorder resulting in lack of cortisol and often aldosterone and overproduction of androgens. Raised levels of androgens can lead to increased mass in the laryngeal tissues, which may lower the fundamental frequency (F0) of the voice. D...
