Question

A woman may develop beard and moustache due to

• A. hypersecretion by adrenal cortex
  
• B. hypersecretion of thyroxine
• C. hyposecretion of adrenaline
• D. hyposecretion of thyroxine

Answer 1

The correct option is A hypersecretion by adrenal cortex


Adrenal gland can be divided into two parts:

• Adrenal cortex and
• Adrenal medulla

Adrenal cortex further has three layers:

• Zona glomerulosa
• Zona fasciculata
• Zona reticularis

Zona reticularis region secretes adrenal androgens. In women, it is the major source of androgens. In females, adrenal androgens cause suppression of feminine characters. Hence, its hypersecretion can result in development of beard and moustache.

Thyroxine and adrenaline are not sex hormones and will not develop beard and moustache.
