Testosterone is a hormone produced primarily in the testicles of men and the ovaries of women, although small amounts are also produced in the adrenal glands. It is responsible for the development of male characteristics, such as increased muscle mass, bone density, and facial hair, and also plays a role in libido, mood, and cognitive function.
Low testosterone levels can lead to a number of health problems, including erectile dysfunction, infertility, fatigue, and depression. Boosting testosterone levels can help to improve these symptoms and restore overall health and well-being.
