Why does a man's genitals itch?

In our daily lives, as the pace of life continues to accelerate, many men are often busy with work all day and ignore their health problems. Among them, male genital itching is a very common phenomenon, but many men are always careless and think that it is no big deal and they just need to pay more attention to personal hygiene. In fact, this is not the case. Such symptoms are often caused by some diseases. If not treated in time, the disease will become particularly serious. Let's understand what causes male genital itching.

Why does a man's genitals itch?

Disease 1: Scrotal itching

Cause: Local dampness is a major cause of scrotal itching. The scrotum itself has glandular secretions, and sweating is frequent. If you often wear tight, synthetic underwear that is not good at absorbing sweat and is not ventilated, it is easy to cause scrotal itching. Having sex with a woman with candidal vaginitis can also cause scrotal itching due to the irritation of the male genitals by the inflammatory secretions. In addition, mental tension, the stimulation of spicy food, friction, static electricity, and the irritation of the vulva skin by detergent residue on the underwear can also induce scrotal itching.

Symptoms: The skin of the scrotum is itchy, but no rash is visible. Because patients always scratch, the skin in the affected area often becomes thickened and lichenified.

Response: Clean promptly after sexual intercourse; keep the area dry, and use talcum powder on the scrotum appropriately; wear cotton, sweat-absorbent underwear to help ventilation; use mild detergent, and use less soap and laundry detergent; relax your emotions, and use some nerve nourishing drugs such as vitamins B1, B2, and oryzanol; avoid washing with very hot water or using irritating drugs, and avoid eating spicy food to prevent the condition from worsening; scratch as little as possible, because it can lead to a vicious cycle, forming chronic simple lichen (i.e. neurodermatitis) that is more difficult to treat.

Oral antihistamines can be taken to relieve itching, and nonsteroidal anti-inflammatory drugs can be applied to the affected area. It is generally not recommended to use hormonal drugs for external application, because the scrotum can easily absorb these drugs, causing side effects such as skin redness, atrophy and thinning, capillary dilation, and excessive hair growth. However, if other treatments are ineffective and the condition is still relatively serious, weak hormonal drugs can be used for a short period of time under the guidance of a doctor.

Disease 2: Scrotal eczema

Cause: It is related to the individual's eczema predisposition, so allergy is an important inducement, including underwear materials, dyes, shrimp, crab, beef, peanuts, alcohol, etc. in diet, which can induce scrotal eczema. In addition, humidity, friction, mental and nervous factors and seasonal climate can induce or aggravate the disease.

Symptoms: limited to the scrotal skin, sometimes extending to the anus, and rarely to the penis. Severe itching. Rash, erosion, and exudate may be seen.

Response: Eczema is related to hereditary eczema, so it is difficult to correct. The key is to remove or avoid factors that induce and aggravate eczema, such as relaxing, wearing breathable cotton underwear, scratching less, not eating foods that may cause allergies, and not washing the eczema area with hot water, let alone washing too frequently, because doing so can make the skin drier, further aggravate the damage to the skin barrier function, and make it more itchy. Therefore, do not clean too frequently, keep the water temperature low, use less detergent or use a mild and moisturizing detergent, and moisturize the skin immediately after washing to ensure that it will not cause skin allergies.

Vulvar itching caused by fungal infection

Disease 3: Candida infection

Cause: Candida infection is a fungal infection. Diabetic patients have high sugar content in their bodies, poor resistance, and fungi are easy to grow; chronic disease patients who often use immunosuppressants, anti-tumor drugs, and hormones have poor body resistance and are also difficult to resist fungal invasion; long-term use of antibiotics will cause flora imbalance, which is conducive to fungal reproduction; having sex with women with the disease may also cause infection.

Symptoms: Penile itching, red papules and white scaling.

Response: Use antifungal drugs, either orally or topically.

Disease 4: Tinea cruris

Cause: Fungal infection. It often occurs in summer, and young men who love sports and sweat a lot are susceptible.

Symptoms: Itching on the inner upper thigh, base and groin, with small papules, blisters and scaling. Initially red papules, slowly become patches (semicircular or arc-shaped), with clear borders and edges slightly higher than the skin.

Response: This disease is relatively easy to treat, but it is easy to relapse and is easily combined with ringworm of the feet and body, but it generally does not infect the scrotum. Because it is a fungal skin disease, be careful not to abuse drugs containing hormones such as Pi Yan Ping and Pi Kang Cream. Hormones will further weaken the skin's resistance and provide a better growth environment for fungi, and hormones themselves will also promote the growth of fungi. It can be treated with antifungal drugs.

Vulvar itching caused by parasitic infection

Disease 5: Pubic lice

Cause: Lice infection. Living in an environment with poor sanitary conditions such as a hotel or guesthouse, and being infected by using unclean bedding and towels, or being infected by a woman who has the disease through sexual intercourse.

Symptoms: Itching of the pubic and anal hairy areas. There are pearly white eggs the size of a needle tip near the hair root, and some flat, yellow-brown or light reddish-brown insect bodies the size of a pin, covered with dense little feet, and can move. Some are on the hair, while others are close to the hair root or skin. In addition, rusty, powdery substances can be seen on the underwear, which are the excrement of the parasite after sucking blood.

Response: The treatment method is similar to that of scabies. Use insecticide to kill pubic lice. Since insecticide can only kill the hatched adult lice, the pubic hair needs to be shaved and burned to kill the unhatched eggs.

Disease 6: Scabies

Cause: Scabies infection. The infection is similar to pubic lice and can also be transmitted by shaking hands with an infected person.

Symptoms: Itching in the crevices of the fingers, wrists, lower abdomen, and thighs. Small papules can be seen, typically arranged in pairs with blood crusts. Sometimes lead-gray, linear tunnels can be seen in the epidermis, and the worm body can be seen at the end of the tunnel. Tunnels can also be seen in the crevices of the fingers. The itching is more obvious at night. After a long time (about a month), red nodules will appear on the penis, glans, and scrotum, which are the size of mung beans, soybeans, or even fingers, and the itching is severe.

Response: Maintain good personal hygiene, wash bedding, clothing and other personal items with boiling water to kill insects. Use insecticides to kill insects. Generally, 20% sulfur paste can be applied to the whole body for three consecutive days, twice a day. People over 12 years old can also use "Scabies Treatment" to kill insects. First, apply it to the whole body below the neck, keep it for 24 hours, then take a shower, and repeat the application after a week. To completely cut off the source of infection, sexual partners need to be treated at the same time. If scabies develops into nodules, antiallergic drugs and corticosteroid ointments are required. However, scabies nodules are allergic reactions and are more difficult to treat.

The above is an introduction to why men's genitals itch. After understanding it, we know that there are many reasons for men's genitals itch, so we must pay special attention to it in normal times. First of all, we must go to a regular hospital for treatment. In addition, we must pay more attention to the details of life in daily life, wear some cotton underwear with good breathability, and don't have too many sexual partners.
