A boy after attaining sexual maturity shows muscular growth, growth of facial and axillary hair, aggressive and low pitch of voice. These changes are attributed to __________ hormone.
- A estrogen
- B testosterone
- C secretin
- D glucagon
Answer & Solution
Correct Answer
(B) testosterone
Step-by-step Solution
Detailed explanation
(B) testosterone,
The Leydig's cells or interstitial cells, which are present in the intertubular spaces produce a group of hormones called androgens mainly testosterone. Androgens regulate the development, maturation and functions of the male accessory sex organs like epididymis, vas deferens, seminal vesicles, prostate gland, urathra, etc. These hormones stimulate muscular growth of facial and axillary hair, aggressiveness, low pitch of voice, etc.
