This hormone increases during puberty and reaches a peak when men are around 20 years old. After 30 years and over, these hormone levels will decrease by about one percent each year. So when men reach the age of 65 years, their normal testosterone levels range between 300-450 ng / dL.
The hormone testosterone is not only owned by men, but also by women. In women, this hormone is produced in the ovaries in small amounts.
