The release of estradiol and testosterone by the gonads (ovaries in females and testes in males) at the onset of puberty is what triggers sexual maturation. These hormones stimulate the development of secondary sex characteristics and the initiation of gamete production. LH and FSH (gonadotropic hormones) and gonadotropin-releasing hormones from the pituitary gland are also involved in regulating the production and release of estradiol and testosterone, but they do not directly initiate sexual maturation.
