Which hormone is produced in males?

• A. Testosterone
• B. Estrogen
• C. Progesterone
• D. Oxytocin

Answer: (A)

Testosterone is the primary male sex hormone. In males it is produced mainly by the testes (the Leydig cells), with smaller amounts coming from the adrenal glands. It drives the development of male reproductive organs and secondary sexual characteristics during puberty, and it supports sperm production and the maintenance of muscle and bone. The production is regulated by the hypothalamic-pituitary-gonadal axis: the hypothalamus releases GnRH, which prompts the pituitary to release LH, and LH then stimulates testosterone production. Negative feedback from testosterone helps keep the system balanced. Other hormones listed can be present in males, but testosterone is the hormone most characteristically produced in male physiology.
