Is the skin of the scrotum the same as normal skin?

The skin of the scrotum shares similarities with normal skin in other parts of the body, yet also exhibits significant differences. Overall, it is thinner and more sensitive, featuring specialized structures adapted to reproductive functions. A detailed analysis is as follows:

In terms of common features, scrotal skin is composed of the epidermis and dermis, and contains hair follicles, sebaceous glands, and sweat glands, fulfilling basic functions such as protecting underlying tissues and regulating body temperature. However, scrotal skin is notably thinner and highly elastic, with abundant folds. This unique structure allows it to contract or relax in response to temperature changes, helping the testes maintain an optimal physiological temperature for normal sperm production.

Compared to the skin on the trunk and limbs, the scrotal skin has a higher density of sebaceous and sweat glands, leading to increased secretion of sweat and oils, which can cause local dampness. Additionally, this area is rich in nerve endings, making it more sensitive to touch and external stimuli such as friction and temperature fluctuations. As a result, discomforts like itching are more likely to occur.

In daily life, it is important to keep the scrotal skin clean and dry. Opt for loose-fitting, breathable cotton underwear and avoid tight clothing that may cause friction or irritation. Use mild cleansing products during washing and avoid excessive scrubbing.
