Question

Ovulation is stimulated by

• A. LH
• B. FSH
• C. Estrogen
• D. Both A and B

Answer 1

The correct option is D Both A and B

A. Luteinizing hormone or LH stimulates growth of ovarian follicles in females. In males this hormone is called interstitial cell stimulating hormone or ICSH and affects the Leydig cells of testes.

B. Follicle stimulating hormone (FSH) is secreted from the anterior part of pituitary gland. It stimulates the growth of ovarian follicles in females and seminiferous tubules in males.

C. Estrogen is the female sex hormone secreted from ovarian follicles and stimulate the development of female secondary sex organs.

Hence, ovulation is stimulated by LH and FSH because these hormones stimulate growth of ovarian follicles and ovum or egg is released from the mature follicles.

So, both options A and B are correct.

So, the correct answer is 'Both A and B'.
