Levels of DHEA-S, a major adrenal androgen, throughout life in humans. [1]Adrenopause is the decline in secretion and levels of adrenal androgens such as dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEA-S) from the zona reticularis of the adrenal glands with age.
Plasma levels of DHEA in adult men are 10 to 25 nM, in premenopausal women are 5 to 30 nM, and in postmenopausal women are 2 to 20 nM. [25] Conversely, DHEA-S levels are an order of magnitude higher at 1–10 μM. [25] Levels of DHEA and DHEA-S decline to the lower nanomolar and micromolar ranges in men and women aged 60 to 80 years.

Diagnosis of androgenic deficiency in males is based on symptoms together with at least two measurements of testosterone done first thing in the morning after a period of not eating. [1] In those without symptoms, testing is not generally recommended. [1] Androgen deficiency is not usually checked for diagnosis in healthy women. [18]
Depression. DHEA levels are lower in those with depression, so supplementation may help.. A 2005 placebo-controlled study looked at men and women aged 45 to 65 with midlife-onset major or minor ...
[2] [1] From the third decade of life on, DHEA and DHEA-S levels gradually decrease. [29] By the age of 70, levels of DHEA and DHEA-S are 80 to 85% lower than those of young adults, and in people more than 80 years of age, DHEA and DHEA-S levels can reach 80 to 90% lower than those of younger individuals. [29] DHEA-S levels are higher in men ...
40-44 years old: 350-473 ng/dL ... In one study of men aged 65 years and over, those with lower testosterone levels experienced reduced sleep efficiency, woke up more in the middle of the night ...
One study found that men with moderate-to-high levels of exhaustion had a 2.7-fold increased risk of heart attack within five years and a 2.25 higher risk within ten years. The study also found a ...
Men with low serum testosterone levels should have other hormones checked, particularly luteinizing hormone to help determine why their testosterone levels are low and help choose the most appropriate treatment (most notably, testosterone is usually not appropriate for secondary or tertiary forms of male hypogonadism, in which the LH levels are ...
