Testosterone is the primary male sex hormone, though it is also present in women in smaller amounts. It is produced in the testes in men and the ovaries in women, with small amounts also produced by the adrenal glands. Testosterone is responsible for the development of male sexual characteristics, such as deepening of the voice, facial hair growth, and muscle development. It also plays a role in maintaining libido, bone density, and red blood cell production. In men, testosterone levels peak in early adulthood and gradually decline with age, while in women, testosterone helps regulate libido, muscle mass, and overall energy levels.

Key Functions:

• Regulates the development of male secondary sexual characteristics.
• Maintains libido and sexual function in both men and women.
• Contributes to muscle and bone mass.
• Supports red blood cell production.
• Affects mood, energy, and cognitive function.

These hormones play vital roles not only in sexual health but also in broader physiological functions across both genders.
