Question: 1 / 400

The testes produce sperm cells and which male sex hormone?

Estrogen

Progesterone

Testosterone

The testes are primarily responsible for the production of sperm cells, but they also produce testosterone, which is the principal male sex hormone. Testosterone plays a crucial role in the development of male reproductive tissues, the promotion of secondary sexual characteristics such as increased muscle mass and body hair, and it is integral to the regulation of libido and sperm production.

While estrogen and progesterone are primarily female sex hormones produced in the ovaries, they are also present in males in small amounts but are not products of the testes. Oxytocin is involved in various physiological functions including social bonding and reproduction, but it is not a product of the testes either. Thus, testosterone is the only hormone listed that is produced by the testes, affirming its significance in male reproductive health and characteristics.
