In the male clinic, many patients come to see the doctor because of itchy penis, flushed foreskin glans, itchy scrotum, genital herpes or genital papules, most of these cases are “skin diseases” of the reproductive system rather than lesions of the reproductive system itself, the following is a brief introduction. The normal foreskin cavity secretes a lipid-like substance, and when the foreskin is too long or circumcised, such substances can accumulate into foreskin scale to stimulate the foreskin and head of the penis causing foreskin glutatitis. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. This inflammation can be both infectious and non-infectious, and clinically, infectious glans penis is more common. It is often seen when the foreskin is too long, there is a history of unclean intercourse, the foreskin of the penis, the glans is mildly flushed, the inner plate of the foreskin and the coronal groove of the glans can have white cheese-like patches, the glans can have pinhead-sized light red papules, if the invasion of the outside of the foreskin and the scrotum, it can be seen scaly red spots. If the navicular fossa is involved, there may be frequent and painful urination. For those with Candida allergy, itching and burning sensation of the penis may occur a few hours after unclean intercourse, and there may be flushing of the foreskin glans. Occasionally, fulminant edematous foreskin glansitis can occur. The main manifestations are marked edema of the penile foreskin, severe itching, and shallow ulcers. The foreskin glansitis caused by drug allergy is a delayed type of perverted glansitis. Glansitis of the foreskin is a common disease in men. In recent years, there has been a significant increase in the number of adults with glans glans, which is related to the openness of people’s sexuality, the increase in extramarital sex, and the abuse of various cleansers. Having unclean sex increases the chances of various infections. In order to avoid contracting STDs, people mostly use some topical disinfectant and anti-inflammatory cleansers to clean and disinfect their vulva. Some people in order to disinfect thoroughly, in the penis foreskin, glans skin parts directly repeatedly applied not according to a certain proportion of diluted cleaning agent solution. This local skin is subjected to strong chemical irritation redness, swelling, exudation and acute inflammation. If the acute inflammation is not properly handled repeatedly, it can eventually form chronic glans penis. The actual fact is that you should seek medical attention and pay attention to your daily hygiene to avoid complications. The actual scrotal eczema is the most common skin disease of the scrotum, often affecting the entire scrotum, the affected area itchy, belong to the allergic reaction, is also a common genital skin disease of men, not sexually transmitted diseases. It is also a common genital skin disease in men, not a sexually transmitted disease. It is commonly known as “hydrangea wind” and “kidney capsule wind”. It is very stubborn and often causes pain or secondary infection due to scratching and inappropriate stimulation. The disease is divided into two kinds of acute and chronic, and is closely related to people’s occupation and living environment. It occurs in the scrotum, sometimes extending to the perianal area, and rarely involving the penis. In the acute stage, the skin is flushed, swollen, vesiculated, oozing and crusted; in the chronic stage, the skin is thickened and rough, wrinkles deepen, pigmentation, a small amount of scales, often accompanied by mild vesiculation and oozing. The duration of the disease is long, often months or years. The causes of scrotal eczema are complex, with internal and external factors. Allergic people, people with chronic mental tension and emotional ups and downs are prone to this disease; in addition, people suffering from some diseases, such as chronic digestive system diseases, gastrointestinal disorders, endocrine disorders and metabolic disorders, are also prone to this disease under the action of external factors. According to Chinese medicine, wind, dampness, heat, blood deficiency and insects are the main causes of the disease. Treatment is based on the principles of removing wind and dampness, clearing heat and detoxification, nourishing blood and moistening dryness, activating blood circulation and removing blood stasis, so as to achieve the effect of driving away evil and helping to stop itching. The acute cases should not be washed with hot water and soap and other irritants; regardless of the acute and chronic, should avoid scratching and excite the disease site, do not wear tight underwear, usually need to pay attention to diet, and avoid eating spicy, hair products. The actual genital herpes is an inflammatory, recurrent sexually transmitted disease caused by the herpes simplex virus invading the skin and mucous membranes of the genital area.

Patients have a history of non-marital sexual contact, multiple sexual partners and unsafe sexual contact. The typical presentation is clusters of corn blisters, vesicles, ulcers, self-induced burning pain, and enlarged lymph nodes in the vicinity of the genital area, which is not difficult to diagnose. However, there are quite a few cases with atypical clinical manifestations, and some clues can sometimes be found by careful history taking and careful observation. As for asymptomatic subclinical infections, they can only be confirmed by specific laboratory tests. However, there is a lack of practical tests available in clinical practice. The prevention of the spread of genital herpes should be based on eliminating the source of infection, cutting off the transmission route and improving the immunity of susceptible people. As the disease is prone to recurrence, repeated attacks often bring worry and anxiety to the patient, patient and careful psychological treatment should be given to encourage the patient to increase confidence in overcoming the disease and actively cooperate with the treatment. Gonorrhea is a sexually transmitted disease caused by gonococcus gonorrhoeae (gonococcus for short) that infects the genitourinary system.

Some patients may have urinary frequency, urinary urgency, and increased nocturia.

Patients mostly have chronic back pain, perineal swelling, nocturnal seminal emission, and blood in semen. In recurrent cases of gonorrhea, urethral stricture may occur, and in a few cases, vas deferens stricture or obstruction and seminal cysts may occur.
