What wikipedia says...

Andropause.

Andropause (sometimes called male menopause^[1]) refers to a reduction of the production of certain hormones such as testosterone and dehydroepiandrosterone, and the consequences of that reduction.^[2] It is associated with a decrease in Leydig cells.^[3][4]

The use of the term "andropause" is not in itself controversial, and the term appears frequently in peer-reviewed journal articles, both with and without scare quotes. The controversy, rather, is over whether andropause is a "state" (the term used by MeSH), or a disorder. The decline in testosterone level with age is well documented,^[5] but there is disagreement over how the "normal" or "healthy" state should be defined. Researchers who oppose the term "andropause" usually don't object to the terms "SLOH" or "ADAM".
