The most biologically active androgen in this list is:

The most biologically active androgen in this list is:

• A. DHEA
• B. DHEAS
• C. Luteinizing Hormone
• D. Estrone

Answer: (A)

Androgen activity among these compounds depends on direct interaction with androgen receptors. DHEA, dehydroepiandrosterone, is produced by the adrenal cortex and has inherent androgenic activity; it can also be converted into more potent androgens like testosterone. In contrast, DHEAS is the sulfated form and is largely inactive as an androgen until it’s desulfated to DHEA, so it mainly serves as a circulating reservoir. Luteinizing hormone is a pituitary hormone that stimulates testosterone production but is not itself an androgen. Estrone is an estrogen, not an androgen, and binds estrogen receptors instead. Therefore, DHEA is the most biologically active androgen among the listed options.
