male menopause [L, mas, male, men, month; Gk, pauein, to cease] , a late middle-age condition affecting some men, who experience anxiety over changes in sexual function and/or desire, increased fatigue, thinning and graying hair, and other signs of aging. Male menopause can stem from actual changes in testosterone levels (over a longer period of time than the more abrupt change in hormone levels typically associated with female menopause). Also called male climacterium.
