Question

During the menstrual cycle of a human female, formation of graafian follicle is stimulated by secretion of which of the following gonadotropin hormones?

विकल्प

• Estrogen and progesterone

• FSH and Estrogen

• FSH and LH

• Progesterone and LH

Answer 1

FSH and LH

Explanation:

The formation of the graafian follicle during the human female menstrual cycle is primarily stimulated by the gonadotropin hormones FSH (Follicle-Stimulating Hormone) and LH (Luteinizing Hormone), secreted by the pituitary gland. FSH initiates the growth of several follicles, and as the cycle progresses, both FSH and LH work synergistically to promote the maturation of one dominant follicle into the graafian follicle. This combined action ensures the follicle develops fully and produces oestrogen, leading up to ovulation.
