What is Perineal Dermatitis?

Perineal dermatitis, also known as saddle sores, is a common skin condition experienced by cyclists. It is caused by the repeated rubbing of the skin against the saddle, leading to an inflammation of the skin. It is characterized by red, itchy bumps or blisters in the area around the genital area, inner thigh and buttocks.

Saddle sores are a common problem for cyclists, with statistics indicating that up to 50% of cyclists experience this condition. Poor bike fit, incorrect saddle height, inadequate padding and long rides are all factors that contribute to this condition. The risk of saddle sores increases with the amount of time spent riding, with cyclists who ride more than 4 hours per day being particularly at risk.

Fortunately, saddle sores can be prevented by using a good-fitting saddle, regularly adjusting the saddle height, and using a chamois cream or other lubricant. In addition, taking regular breaks from cycling and using appropriate cycling clothing can also help to reduce the risk of developing saddle sores.


The Origin of the Term 'Perineal-Dermatitis'

The term “perineal-dermatitis” was first used in the early 1980s by Dr. W.G. Morton, a British dermatologist. At the time, this condition was primarily seen in cyclists, and its cause was unknown. Dr. Morton observed that cyclists experienced inflammation and irritation of the skin in the perineal area. In 1983, he published a paper titled “Perineal Dermatitis in Cyclists” to describe this condition.

In the paper, he hypothesized that the cause of the condition was due to friction from the saddle. He suggested that the irritation could be prevented by wearing padded cycling shorts. His hypothesis was later proven to be correct.

Today, the term “perineal-dermatitis” is widely used in the cycling community to describe the inflammation and irritation of the skin in the perineal area. It is a common condition, and can be prevented by wearing padded cycling shorts.
