Explain the roles of the hormones GnRH, FSH, and LH in the male and female reproductive systems

What will be an ideal response?


ANSWER: In both males and females, gonadotropin-releasing hormone (GnRH) is secreted by the
hypothalamus gland and acts on the pituitary gland to release follicle-stimulating hormone
(FSH) and luteinizing hormone (LH) into the bloodstream. In females, the target of FSH
and LH is the ovary. FSH stimulates primary oocytes to develop into secondary oocytes,
which become surrounded by a layer of cells and form a follicle. LH triggers ovulation and
subsequent formation of the corpus luteum from the remaining follicle cells. In males, the
target of the two gonadotropins is the testes. FSH stimulates Sertoli cells to secrete
molecules required for spermatogenesis while LH stimulates the Leydig cells to secrete
testosterone.
