Question

Grown up individual may lack sexual traits due to

• B. Decreased secretion of sex hormones
• C. Excess secretion of sex hormones
• D. Glandular disease

Answer 1

The correct option is B Decreased secretion of sex hormones

Sexual characters in males and females develop due to sex hormones which are testosterone in males and oestrogen in females. Testosterone is secreted from Leydig's cells in testis while oestrogen is secreted from ovarian follicles in females. These sex hormones are steroid hormones and regulate various sexual characters and development of secondary sex organs. A decreased secretion of sex hormones will lead to underdeveloped sexual traits.

So, the correct answer is 'Decreased secretion of sex hormones'.
