Novel androgen therapies including selective androgen receptor modulators.

Male hypogonadism is associated with reduced quality of life and the development of co-morbidities including obesity, diabetes mellitus, and dyslipidaemia. The mainstay of treatment for male hypogonadism is testosterone replacement therapy (TRT). However, TRT has recognised side effects including impaired spermatogenesis and there are concerns regarding its use in men with concurrent cardiovascular disease. Thus, there has been an impetus to develop novel androgen therapies for treating male hypogonadism to mitigate the side effects of TRT. This review will discuss the benefits and adverse effects of TRT, and novel therapies including nasal testosterone, aromatase inhibitors, selective oestrogen receptor modulators, and selective androgen receptor modulators.
