Question

DHEA is a hormone involved in muscle growth, bone density, and the functioning of the cardiovascular system. DHEA production increases until about age 30 years of age and then decreases. The level of DHEA at age 80 is about what percentage of what it was at age 30?

Answer 1

Answer:

5%

Explanation:

The adrenal cortex in both males and females produce a small amount of weak androgens. One of the major weak androgen secreted by adrenal cortex is dehydroepiandrosterone (DHEA).

Levels of dehydroepiandrosterone secretion exhibit changes with age. The dehydroepiandrosterone secretion increases till the age of 20-24 years and falls off with increasing age after the age of 30 years in both males and females. The DHEA production at the age of 80 years is about 5% of its secretion at the age of 30 years.
