Andropause
（重定向自Manopause）
Andropause – also colloquially known as male menopause – is said to be the result of a gradual drop in testosterone, which is an androgen. The medical community is currently debating whether or not men really do go through a well-defined menopause. The condition "andropause" is currently not recognized by the World Health Organization. When andropause occurs, it is considered to be a deficiency state in which the hormone testosterone goes below the normal range for an aging male.
