If you’re a male and you’ve been feeling a bit more grumpy than usual, you may not be imagining it. There’s actually a condition called Irritable Male Syndrome (and it’s similar to andropause and so-called male menopause). The condition doesn’t mean the loss of male reproductive ability (as what happens in menopause with women), but it is characterized by a dramatic drop in the hormone testosterone, which can wreak havoc with a number of male functions. It can also change your mood for the worse, as the name suggests.
Here are seven things to know about it…
1. The Condition was First Observed in Sheep
While symptoms of male menopause have been observed for quite a while in the health world (and typically set in around age 50), the term “irritable male syndrome” or IMS was apparently first coined in 2001 by Dr. Gerald Lincoln in Scotland, according to an article in the Huffington Post.
It explains that the research of the doctor shows that male Soay Sheep are pretty happy-go-lucky during mating season (when testosterone levels are high), and not so much during the off-season. The sheep become irritable and fight each other, often causing injuries, notes the source.
