    Solution:

    Oxytocin (OT) hormone is produced by hypothalamus under the influence of nervous stimulation. It causes contraction of the smooth muscles of the uterus and myoepithelial cells lining the duct of the mammary gland. Hence, it is also called as birth hormone and milk ejection hormone. 

    Prolactin (PRL), secreted from anterior pituitary gland, acts to initiates and maintain milk secretion by the mammary gland, hence it is known as hormone of maternity and milk stimulating hormone. 

    FSH (follicle stimulating hormone), secreted by anterior pituitary gland, is a gonadotrophic hormone. It stimulates spermatogenesis and growth of seminiferous tubules in testes in male and maturation of Graafian follicle and secretion of estrogen and progesterone from corpus luteum in female.
