DeutschAdrenopause
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.[2][3] Levels of adrenal androgens start to increase around age 7 or 8 years (adrenarche), peak in early adulthood around age 20 to 25 years, and decrease at a rate of approximately 2% per year thereafter, eventually reaching levels of 10 to 20% of those of young adults by age 80 years.[2][1] It is caused by the progressive apoptosis of adrenal androgen-secreting cells and hence involution of the zona reticularis.[2][3] It is analogous to andropause in men and menopause in women, the abrupt or gradual decline in production of sex hormones from the gonads with age.[4]
DHEA can be supplemented or taken as a medication in the form of prasterone to replace adrenal androgens later in life if it is desired.[2] Some clinical studies have found benefits of DHEA supplementation in the elderly and people with adrenal insufficiency.[2]
