Since men do not go through a well defined period referred to as menopause, some physicians refer to this problem as androgen (testosterone) decline in the aging male. Men do experience a decline in the production of the male hormone testosterone with aging, but this also occurs with some disease states such as diabetes. Along with the decline in testosterone, some men experience symptoms such as fatigue, weakness, depression, and sexual problems. The relationship of these symptoms to the decreased testosterone levels is still controversial.
Unlike menopause in women which represents a well-defined period in which hormone production stops completely, male hormone (testosterone) decline is a slower process. The testes, unlike the ovary, does 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.
Male menopause, also called andropause, refers to a gradual decline in a man's testosterone levels. Not all men will go through andropause and it is unknown why those that will, do. Testosterone is the male sex hormone that is responsible for creating and releasing sperm, initiating sex drive and providing muscular strength.
Hormone levels tend to peak around the ages of 15 to 18 in most males. Sometime during his mid to late 20s, a man's hormone levels will begin to drop slowly. Usually, these hormone levels will remain at a healthy level, but some men will see their testosterone levels drop significantly by the time they are 40. By age 50, half of all men will experience a significant reduction in testosterone levels, causing a variety of uncomfortable ailments.
