What Is Male Menopause?
Because men do not go through a well-defined period referred to as menopause, some doctors refer to this problem as androgen (testosterone) decline in the aging male, or what some people call low testosterone. Men do experience a decline in the production of the male hormone testosterone with aging, but this also occurs with conditions such as diabetes. Along with the decline in testosterone, some men experience symptoms that include fatigue, weakness, depression, and sexual problems. The relationship of these symptoms to decreased testosterone levels is still controversial.
Unlike menopause in women, when hormone production stops completely, testosterone decline in men is a slower process. The testes, unlike the ovaries, do not run out of the substance it needs to make testosterone. A healthy male may be able to make sperm well into his eighties or longer.
However, as a result of disease, subtle changes in the function of the testes may occur as early as 45 to 50 years of age, and more dramatically after the age of 70 in some men.
