Testosterone is a hormone primarily produced in the testes in males and in smaller amounts in the ovaries and adrenal glands in females. It plays a crucial role in the development of male physical characteristics, such as increased muscle mass, bone density, and body hair. Testosterone also influences mood, energy levels, and libido in both men and women. In addition to its role in physical development, testosterone is important for overall health. Low levels of testosterone can lead to various health issues, including fatigue, depression, and decreased sexual function. Maintaining balanced testosterone levels is essential for both men and women to support their well-being.
