    Yellow stains on men's underwear may be caused by contamination of secretions, because increased penile secretions in men will form urine stains in underwear, and factors such as excessive blood bilirubin or moisture in the scrotum can also cause yellowing of the crotch. Therefore, men should pay attention to the hygiene of the penis to avoid the occurrence of inflammation. There are many reasons for yellow stains on men's underwear. Men can learn about it in this article.

    Why does the crotch of men's underwear turn yellow?

    01 Secretion pollution

    After a man reaches puberty, his endocrine system is strong, and his crotch sweat glands and penile secretions increase greatly. As a result, mixed pollution of urine (residual), sweat and penile secretions (sexual excitement secretions and residual semen) is formed when wearing underwear.

    02Excessive blood bilirubin

    Any cause that causes an increase in blood bilirubin can cause an increase in the yellow pigment content in secretions and sweat, leaving yellow marks on personal clothing.

    03The scrotum is too moist

    According to Chinese medicine, it is too much moisture. Some men's underwear is always damp, which may be due to scrotal eczema. It manifests as the scrotal area is always moist and slightly itchy.

    ①During an acute attack, the symptoms are mostly flushing, itching, and pimples on the scrotal skin. If the itching is scratched a lot, smooth red skin can be exposed.

    ②During a subacute attack, symptoms include severe itching of the scrotum, loss of appetite, loose stools, yellow urine, and sometimes mild erosion of blisters.

    ③In chronic attacks, the itching is intermittent, and the itching is aggravated by mental stress, drinking alcohol, or eating spicy food. The skin of the scrotum feels hard and the surface color of the skin is dark red or purple-brown. This disease is one of the skin diseases, and it is also a kind of male disease. People who are fat and have localized hyperhidrosis are prone to this disease, and most of them are middle-aged and elderly male patients.

    04Genital infection

    Reproductive infections are also called sexually transmitted diseases. The more common reproductive infections include gonorrhea, syphilis, non-gonococcal urethritis, genital warts, I. trachomatis, chancroid, genital herpes, trichomoniasis, hepatitis B and AIDS.

    What to do if the crotch of men's underwear turns yellow?

    1. People with allergies, long-term mental stress, and large mood swings should relax.

    2. People suffering from some diseases, such as chronic digestive system diseases, gastrointestinal dysfunction, endocrine disorders, and metabolic disorders, may also easily cause yellowing of their underwear under the influence of external factors. Seek medical advice promptly and get treatment as soon as possible.

    3. The living and working environment is humid, and the air humidity is relatively high, which can easily make men's lower body wet and cause their underwear to turn yellow. You should improve your working and living environment and get more sun.

    4. External stimulation, cold or heat, excessive sweating, excessive scratching, tight underwear, friction with foreign objects, wearing chemical fiber underwear, etc. can induce scrotal eczema, thereby causing men's underwear to turn yellow. Everyone must be wary of these problems.

    A pair of dirty underwear contains an average of 0.1 grams of feces. Chemical fiber underwear can inhibit sperm production, so it is best to change men's underwear every six months. The longest period of changing underwear should not exceed 2-3 days. After washing, do not expose it directly to the sun. Let it dry in the shade first, and then put it in the sun for disinfection. Loose underwear is more in line with men's health needs.
