“Manapause” ,if you will, while not quite the female equivalent of menopause is still marked by distinctive physiological changes in men.

Unlike women, men experience hormonal changes gradually over a period of many years. A man’s testosterone level peaks around age 20, and then steadily declines from about 40 on, so ultimately it’s about 50% less by the time he is 80 years old. The result can sometimes be a condition called “andropause,” which potentially affects millions of American men.

The symptoms – irritability, changes in sexual function and erectile quality, low desire – can have a very real impact on a guy’s sex life and his overall relationship.
