Hormonal changes are a normal part of many phases of life ― for both women and men. Yet one is talked about more than the other. (We’ll let you guess which one.)

One example? Hormonal changes in middle-aged men are often brushed off as a “midlife crisis,” but experts say that couldn’t be further from the truth. For men in their 40s or 50s, hormonal changes (such as a testosterone decrease) along with societal pressures can lead to a range of physical and emotional symptoms, said James Davis, a coaching psychologist and owner of Midlife Mentors in the U.K.

“Irritable male syndrome” is a condition that describes the drop in testosterone and other hormonal changes that can happen as men age. It is not a clinical diagnosis but is a recognized issue that was named by Scottish scientist Gerald Lincoln.

This time in life is more formally known as andropause, according to Davis. (This is the term Davis prefers.) “I think the serious side of this is a lot of men are adversely affected with their psychological health,” Davis said.

Andropause is a time of increased anxiety, lower confidence, worries about midlife accomplishments and more. These issues impact men on a day-to-day basis and can add major stress in partnerships.
