As everybody beyond the fifth decade
of life will experience sooner or later a
decrease in muscle
function, a
decrease in immune
function, a
decrease in plasma albumin concentration, and / or an increase in TNF - α concentration, it is hypothesized that practically everybody experiences sooner or later an

Circulating testosterone levels decline with increasing
age but do not appear to be significantly affected by the menopausal transition.8
As early as the 1940s, testosterone was reported not only to alleviate menopausal symptoms but also to restore libido.9 In recent years, evidence has accumulated supporting the hypothesis that the decline in endogenous testosterone levels is associated with menopausal symptoms, including decreased libido, worse moods, and poorer quality of life.10 Clinical trials have demonstrated that exogenous androgens in conjunction with estrogens can ameliorate symptoms affecting sexual function and general well - being.11, 12 In addition, studies have found beneficial effects of androgen therapy on bone mineral density.13 -
