Testosterone is the primary male sex hormone that plays multiple crucial roles in the body, particularly in males. Its main functions include:
- Development of male reproductive tissues such as the testicles and prostate.
- Promotion of secondary male sexual characteristics, including increased muscle mass and strength, growth of facial and body hair, deepening of the voice during puberty, and growth of the penis and testes.
- Regulation of sex drive (libido) and sperm production.
- Support of bone growth and maintenance of bone density.
- Stimulation of red blood cell production.
- Influence on mood, cognition, and overall well-being.
Testosterone also plays a role in male physical development during puberty, such as increased height, stronger muscles and bones, and the appearance of male hair patterns. Low testosterone levels can lead to reduced libido, decreased muscle and bone mass, fatigue, depression, and other health issues. The hormone is produced primarily in the testes and is regulated by signals from the brain through the pituitary gland
