What are the symptoms of hypogonadism (low testosterone)?

Symptoms and signs of testosterone deficiency occur as a result of low testosterone levels or insufficient testosterone action, and hence benefit from testosterone therapy (regardless of whether there is an identified underlying etiology).1,6

Insufficient testosterone action (even at normal testosterone levels) can be caused by less sensitive androgen receptors (which is genetically determined)7 or elevated SHBG levels (which bind to testosterone and reduce the free “active” serum fraction of testosterone.8

Due to the multiple effects of testosterone, the health consequences of hypogonadism are wide-ranging with signs and symptoms affecting sexual, physical, metabolic and psychological domains.
