Why do boys have itchy genitals?

Don't think that only women will experience private itching. In fact, more than 20% to 30% of men have experienced varying degrees of private itching. Especially in hot weather, the male genitals with more sebaceous glands are prone to itching. However, itching is only an external manifestation, and there may be hidden medical and safety risks behind it. So what is the cause of male private itching? Let's learn about it together.

Why do boys have itchy genitals?

1. Tinea cruris and tinea buttocks

Men who are obese and prone to sweating often have their vulva in a sweaty, wet and cold environment, which is easy to breed and multiply bacteria, causing tinea cruris or tinea buttocks. Sometimes it will continue to erode the male genitals. In the early stage of the disease, it mainly manifests as a small rash and itching; later, it spreads outward and may produce annular protrusions on the edges, uneven annular or various skin lesions in the center, accompanied by scaling. You can apply plasters according to the doctor's instructions.

2. Allergic dermatitis

Some men may experience allergic symptoms in their private parts after wearing a condom, with severe itching.

There are also a small number of men with allergic constitutions. After wearing chemical fiber underwear, because the clothes are close to the vulva and are easily wetted by sweat, they will develop papules and erythema on the skin in contact with the underwear, causing itching.

3. Scrotal itching

One of the main causes of scrotal itching is local dampness and coldness. Because the scrotum itself has glandular metabolism and sweats a lot, if you often wear chemical fiber and tight underwear, the sweat absorption and breathability are poor, which is easy to cause scrotal itching.

After having sex with a woman suffering from trichomoniasis vaginitis, the man's genitals are irritated by the inflammatory secretions, which can also cause scrotal itching.

In addition, spicy food, electrostatic induction irritation, detergent residue on underwear, and tension and anxiety can also cause scrotal itching.

6. Trichomonas balanoposthitis

Due to lack of attention to environmental hygiene or infection by pathogens, men suffer from trichomonas balanitis, which can cause dryness and scaling of the foreskin of the penis or produce erythematous and desquamative rash, causing tingling and itching.

5. Pubic lice

Pubic lice refers to pubic lice that live on human anal hair and male pubic hair. They bite the surrounding skin and cause itchy infectious parasitic infections.

If the body of a louse is the size of a white sesame seed, it can bite the human skin, introducing harmful saliva into the body. It will also continue to physically suck blood and defecate, causing itching and inflammatory mediators in the private skin.

6. Scabies

Scrotal scabies is caused by scabies, which is similar to pubic lice. It can also be transmitted by shaking hands with the patient. The patient's scrotal skin will have dark red lumps that are the size of soybeans and higher than the surface of the skin. The surface is smooth, with clear edges and itchy parts.

It is particularly important to note that if men experience itching in their private parts, they should not scratch randomly, otherwise it is easy to cause the wound to rupture and cause more serious infection. The appropriate approach is to go to a regular hospital for medical treatment as soon as possible.
