There are many things that may cause a man to have dry skin on his scrotum. For starters, this problem can occur simply because his skin is dry in general. Sometimes dry, irritated skin develops in this area because it is very sensitive. Even something as simple as pants or underwear that chafe the area may contribute to this issue. A skin condition such as eczema may be at fault in some cases. Sexually transmitted diseases (STDs) and other types of infections may cause dry skin on the scrotum as well.

Often, dry skin on the scrotum doesn’t develop because a person has a skin condition or another type of underlying problem; it may develop just because a person is prone to dry skin. In such a case, there are some easy steps he can take to deal with this issue. For example, he may drink more water, as adequate hydration helps to protect against excessive drying of the skin. He may also avoid taking very hot baths and showers, as both of these serve to make dry skin worse. Additionally, using a moisturizer that is free of perfumes and dyes on the affected area often proves helpful as well.

Sometimes a man develops dry skin on the scrotum because the skin in this area is sensitive and vulnerable to whatever touches it. As such, a person may develop dry, irritated skin in response to harsh chemicals found in some soaps and cleansers. Sometimes a man's clothing can even be at fault. For instance, dry skin on the scrotum may develop when a man's pants, shorts, or underwear chafes his skin in that area. It may even develop when the detergent in his clothing irritates his skin.

It sometimes happens that the skin on a man’s scrotum becomes overly dry in response to a skin condition. For example, eczema may cause this symptom. This skin condition is marked by dry, itchy, inflamed skin that sometimes develops oozing bumps as well. Doctors aren’t sure what causes the condition, but skin that is already dry and irritated is more prone to it. Likewise, there is some evidence that problems with the immune system play a role.

Dry skin on the scrotum may also develop as the result of an infection. For example, an STD infection may cause or contribute to the problem. Sometimes yeast infections cause dry, itchy, irritated skin as well.
