Irritable male syndrome (IMS), sometimes called Del syndrome, is defined as a state of hypersensitivity, anxiety, frustration, and anger that occurs in males and is associated with biochemical changes, hormonal fluctuations, stress, and loss of male identity.[1] This term covers symptoms thought to be caused by a drop in testosterone levels in male mammals.[2] It is a striking feature in mammals with seasonal breeding patterns at the end of the mating season.

History [edit]
A doctor from a Medical Research Council's Human Reproductive Sciences Unit in Edinburgh, Scotland, coined the term after studying the mating cycle of Soay sheep. In autumn, he found that the rams' testosterone levels soared and they mated. In the winter, testosterone levels fell and they lost interest in sex. He also found that as testosterone levels fell, rams became nervous and withdrawn, striking out irrationally. Dr. Lincoln has observed these same changes in behavior in red deer, reindeer, and Indian elephants.
IMS in humans [edit]
In humans, irritable male syndrome is referred to as the andropause, defined as symptomatic of hormonal, physiological, and chemical changes that can occur in all men. These changes are considered[by whom?] to affect physical, psychological, interpersonal, sexual, and nutritional aspects of men's health. Stress tends to be a common trigger, especially when combined with rapid hormone changes later in life.[3]
Symptoms [edit]
Symptoms, in humans, caused by a drop in the male hormone testosterone include:
- Anger and social withdrawal[4]
- Irritability
- Hypersensitivity
- Anxiety
- Hot Flashes
- Mood swings
- Depression
- Lack of libido
- Back and head aches
External causes [edit]
External factors that can cause testosterone levels to fall include certain forms of medication, poor diet, excessive alcohol consumption, illness, lack of sleep, lack of sex, stress or surgery.
