The second set of glands in the Endocrine System are the Gonads: the gonads consist of the ovaries in females and testes/prostate in males, and are responsible for producing the sex hormones of the body, which determine the secondary sex characteristics of adult males and females.
The testes produce androgen
testosterone after puberty starts, which effects many parts of
the body: muscles, bones, sex organs, and hair
follicles. During puberty, testosterone controls the growth and
development of the sex organs and body hair, (pubic, chest, and facial). With the inherited genes for
baldness, testosterone triggers the onset of androgenic alopecia,
commonly known as male pattern baldness.
The ovaries are located in the pelvic
cavity/uterus in females. The ovaries produce progesterone and
estrogens. Progesterone is most active in females during ovulation
and pregnancy where it maintains appropriate conditions to support a
developing fetus. Estrogens function as the primary female sex
hormones. The release of estrogen during puberty triggers the
development of female secondary sex characteristics such as uterine
development, breast development, and the growth of pubic hair.
