What is the function of testosterone?

• A. Development and maintenance of secondary sex characteristics
• B. Digestive enzyme production
• C. Regulates body temperature
• D. Stimulates bone growth only

Answer: (A)

Testosterone acts as the primary male androgen that drives the development and preservation of male secondary sexual characteristics and reproductive function. At puberty it promotes facial and body hair growth, deepens the voice, increases muscle mass, and helps the male reproductive organs mature and function. It also supports spermatogenesis and helps maintain bone density. Producing mainly in the testes under LH stimulation, it can be converted to other active forms in different tissues, which broadens its impact beyond just one system. Because of these widespread effects, describing its role as the development and maintenance of secondary sex characteristics best captures its essential function. The other options don’t fit because they refer to processes not primarily driven by testosterone (digestive enzymes, body temperature regulation) or overly narrow effects (bone growth only).
