Hormones play an important role in the sexual maturity in a male and female. Sexual maturity in humans starts at puberty which is guided by hypothalamus by secreting hormone that acts on pituitary gland. The anterior portion of the pituitary gland in response secretes gonadotrophins. Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH) act on the gonads of female and male which secrete other hormones in the response.
