男生怎么判断自己得了性Disease

In general, men can assess whether they have contracted a sexually transmitted infection (STI) by observing abnormal genital discharge, changes in the skin or mucous membranes of the genital area, urinary abnormalities, genital pain or itching, and relevant exposure history. If any discomfort or symptoms occur, it is recommended to seek timely medical evaluation and treatment at a正规 hospital. Specific details are as follows:

1. Abnormal Genital Discharge

Under normal circumstances, men produce minimal genital discharge that is odorless. The appearance of yellowish-green or grayish-white purulent discharge, especially if accompanied by a foul fishy odor or curd-like substances, often indicates inflammation caused by pathogen infection. This may be a sign of diseases such as gonorrhea or non-gonococcal urethritis. Such discharge results from abnormal exudation due to pathogens irritating the mucous membranes.

2. Changes in Genital Skin or Mucous Membranes

The appearance of red patches, papules, blisters, ulcers, or wart-like growths on the genital area may indicate an STI. For example, syphilis may present with a hard chancre (painless ulcer), while genital warts (caused by HPV) may appear as cauliflower-shaped or papillary growths. These lesions result from pathogens damaging the skin and mucosal tissues, leading to localized pathological changes.

3. Urinary Abnormalities

Symptoms such as frequent urination, urgency, painful urination, urine stream splitting, or a narrowed urinary stream may suggest urethral inflammation due to pathogen infection. Inflammation causes congestion and swelling of the urethral mucosa, interfering with normal urine flow.

4. Genital Pain or Itching

Persistent dull ache, distension, or severe itching in the genital region may be caused by an STI. For instance, genital herpes can cause localized pain, while pubic lice infestation leads to intense itching due to parasite bites. Pain typically arises from inflammatory irritation of nerves, while itching is usually triggered by pathogens or their metabolic byproducts stimulating nerve endings in the skin or mucosa.

5. Exposure History

If there has been recent unprotected high-risk sexual activity or contact with personal items used by someone with an STI, the risk of infection significantly increases. Individuals should remain highly vigilant—even in the absence of symptoms—and consider prompt medical screening.

If any of the above symptoms are noticed, do not self-medicate or delay seeking care. Visit the dermatology and sexually transmitted diseases department of a正规 hospital for professional evaluation and accurate diagnosis. Avoid sexual activity during treatment to prevent transmission to partners. Maintain good personal hygiene by changing underwear regularly, keeping the genital area clean and dry, and avoiding sharing personal items with others.
