History and Physical Symptoms highly suggestive of androgen deficiency in men include reduced sexual desire, decreased spontaneous erections, loss of axillary hypogonaidsm pubic hair, declining testicular volume, hot flashes, low or zero sperm count. Altered SHBG can be anticipated in obesity, guidwlines, chronic illness, elderly, especially when TT is in the low to normal range. Low serum testosterone levels are associated with increased risk of mortality in a population-based cohort of men aged 20— Male hypogonadism, acquired or congenital, can be caused by defects that interfere with the hypothalamic-pituitary-testicular axis. Defects, whether acquired or congenital, that interefere with interactions in the hypothalamic-pituitary-testicular axis can cause male hypogonadism It is essential to distinguish between primary hypogonadism which originates in the testes and secondary hypogonadism which originates in the hypothalamus or pituitary. The development of chronic illnesses, including diabetes, cardiovascular disease and inflammatory disorders, is associated with a contemporaneous accelerated rate of aging-related T decline, ranging between 1.

Low serum testosterone levels are associated with increased risk of mortality in ,ate population-based cohort of men aged 20— The hypothalamus-pituitary- testicular HPT axis is tightly regulated in an interdependent fashion to maintain hormonal homeostasis. Secondary hypogonadism results from disruption of the hypothalamic-pituitary gonadal axis with low or normal serum gonadotropin levels. Aging Male.
