It was only up until a few years ago that scientists and doctors realized that indeed men do go through a change of life (much like menopause for women, but not as severe) and it is called, Andropause. For years it was called a 'mid-life crisis' starting around the age of 40 where men felt they were losing their identity and wanting to regain their youth and also find out if other females were still attracted to them. Andropause varies for different men. Symptoms can be moodiness; depression; lack of energy; lack of interest in a sexual relationship with their spouse; not sleeping well while some men may get a new hair style; new clothes; start acting younger; angry at their spouse for not keeping up with them; blaming the spouse; women watching and possibly cheating.
