Why does the scrotum itch?

The scrotum is part of the male reproductive organ. The hot summer is the main season for bacteria to breed, and various diseases will be spread at this time. Scrotal itching is also a disease that is more likely to occur in this season. Many people do not know about this disease. Let's find out why the scrotum itches?

Internal factors

This is mainly due to the unreasonable design of traditional men's underwear.

Due to the unique body structure of men, and because that unique part is very important, men's underwear actually has a great impact on men. However, because men are more casual in nature, they often endure and ignore the discomfort caused by poorly designed underwear.

Men's sexual function and fertility are closely related to the temperature of the testicles. The contraction of the scrotum is to regulate the temperature of the testicles to be 2 to 3 degrees below the body temperature. If you touch the scrotum with your hand, you will feel it is cooler than other parts of the body. Only when the testicles are 2 to 3 degrees below the body temperature can the secretion of testosterone reach its best. Testosterone can promote sperm production, improve sperm quality and enhance sexual function.

Most traditional underwear on the market are designed with double layers in the front, which wraps the penis and scrotum together, leaving the scrotum in a hot and humid environment for a long time. Over time, it is easy to cause scrotal eczema, sexual dysfunction, severe varicocele and even infertility. The unreasonable design of underwear is the main external cause of scrotal eczema and causes scrotal itching.

External factors

① The living and working environment is humid, and the air humidity is relatively high;

②External stimulation, cold or hot, excessive sweating, excessive scratching, etc.;

③ Tight underwear, friction with foreign objects, and wearing synthetic underwear can induce scrotal eczema;

Scrotal eczema can also be acquired through sexual transmission. Clinically, 20% of scrotal eczema patients are infected through unhealthy sexual transmission.

Scrotal itching is a very common symptom, especially in young men. Generally speaking, it may have the following reasons:

(1) It is more common in people who do manual labor, especially in the summer, when the genitals are hot, sweaty, humid, and poorly ventilated. The scrotal skin is stained by sweat and rubbed by underwear, causing itching. Wearing tight jeans or non-absorbent, non-breathable nylon underwear can also cause this condition.

(2) Riboflavin (vitamin B2) deficiency can lead to scrotitis. The scrotum will show changes such as erythema, dryness, scaling, papules and scabs, accompanied by itching. At the same time, angular cheilitis, glossitis and oral ulcers may also occur.

(3) Scrotitis caused by fungi, such as candidal scrotitis and tinea cruris involving the scrotum, can cause scrotal itching.

(4) Neurodermatitis and eczema in the scrotum can cause itching. In summary, general scrotal itching is not a sexually transmitted disease. As long as there is no history of sexual promiscuity, genital ulcers or growths, urethral discharge, etc., there is no need to worry about contracting a sexually transmitted disease.

The above are the various reasons why the scrotum itches. Many patients do not pay attention to their hygiene after itching, which makes the condition worse. The scrotum must be kept dry. Wash it every day and change underwear frequently. If the itching is particularly obvious, do not scratch it with your hands, as this will allow bacteria to infect other parts.
