What are the gonadotropins ? State their functions

These are the gonad stimulating hormones secreted by the anterior lobe of pituitary, e.g., follicle stimulating hormone (FSH), luteinizing hormone (LH) and prolactin (LTH).
(a) FSH stimulates the gonads to produce sperms and ova; stimulates the ovaries to secrete female sex hormone estrogens.
(b) LH stimulates the maturation of Leydig’s cell of testes for secretion of testosterone; stimulates the secretion of estrogens and progesterone in the ovary.
(3) Prolactin helps in the secretion of milk from the mammary glands after the birth of the child
