Symptoms of testosterone deficiency affect approximately 1 in 200 men and may include:
- reduced libido
- depressed mood
- loss of energy
- erectile dysfunction
- aches and pains
This condition is commonly referred to as “Andropause” and less often as “Androgen Deficiency in the Aging Male” (ADAM).
A man may be considered hypogonadal at any age if total testosterone is less than 200 ng/dl, or bioavailable testosterone is less than 60 ng/dl. Basaria and Dobs of Johns Hopkins University recommend that elderly men with symptoms of hypogonadism and a total testosterone level < 300 ng/dl should be started on hormone replacement.
