irritable male syndrome

Show Summary Details

Quick Reference

A behavioural state of irritability and aggression in adult male members of seasonally breeding mammalian species following a decline in testosterone at the end of a mating season, also occurring in men when testosterone declines as a consequence of ageing or stress, with additional symptoms of lethargy, and depression. Age-related testosterone decline in men is also called androgen decline in the ageing male (ADAM) or ageing male syndrome (AMS). See also andropause, climacteric, testosterone replacement therapy (TRT). [First used in an article by the English reproductive biologist Gerald A. Lincoln in the Journal of Reproduction, Fertility and Development in 2001, echoing the term irritable bowel syndrome]
