In men, the testes are where testosterone is largely produced. A tiny amount is also produced by the adrenal glands. A healthy libido and sperm production depend on testosterone. The main reproductive hormone produced by the biological male body is testosterone. Although the ovaries in women also make testosterone, the amounts are far less significant. The testes and adrenal cortex in men create testosterone. This important sex hormone affects a wide range of bodily functions in men, such as:
- The reproductive organ development before birth
- The development of pubic hair, a deeper voice, and accelerated growth throughout puberty
- Increasing libido or sex drive
- Maintaining strength and muscular mass over the long period
- Facilitating sperm production for reproduction
