男性常见性传播疾病的症状与体征
Understanding the signs and symptoms of common sexually transmitted diseases (STDs) in men is crucial for early detection and treatment. This article outlines the symptoms, transmission methods, and preventive measures for common STDs in men.

Common STDs in Men and Their Symptoms

1.  Chlamydia 

Transmission: Spread through anal, oral, or vaginal sex with an infected individual.

Common Symptoms:

  • Pain or a burning sensation while urinating.
  • Penile discharge.
  • Swollen or painful testicles.

Note: Many people who contract chlamydia may not exhibit symptoms, but can still spread the infection.

2.  Gonorrhea 

Transmission: Spread through anal, oral, or vaginal sex with an infected individual.

Common Symptoms:

  • Pain or a burning sensation while urinating.
  • Green, white, or yellow penile discharge.
  • Swollen or painful testicles.

Note: Some individuals with gonorrhea may not show any symptoms but can still transmit the infection.

3.  Hepatitis B 

Transmission: Spread through contact with the blood or bodily fluids of an infected person, including sexual contact.

Common Symptoms:

  • Loss of appetite.
  • Fatigue.
  • Low-grade fever.
  • Muscle and joint pain.
  • Nausea and vomiting.
  • Jaundice (yellowing of the skin and eyes).

Note: Even without symptoms, the virus can continue to damage the liver if left untreated.

4.  Herpes Simplex 

Transmission: Spread through direct contact with the mouth or genitals of an infected person, including sexual intercourse and kissing.

Common Symptoms:

  • Small blisters or ulcers on the genital area, anus, or mouth.
  • Tingling, itching, or burning sensation in the affected area.
  • Pain in the lower back, buttocks, thighs, or knees.
  • Swollen lymph nodes in the groin.
  • Loss of appetite, fever, and general discomfort.

Note: Some individuals may not experience symptoms but can still transmit the virus.

5.  Human Papillomavirus (HPV) 

Transmission: Spread through skin-to-skin contact, primarily during anal, oral, or vaginal sex.

Common Symptoms:

  • Genital warts (flat and flesh-colored or clusters of small bumps that appear cauliflower-like).
  • Warts in the mouth or throat (spread via oral sex).

Note: Most people with HPV will not have symptoms, but some may develop warts or experience complications such as cancers of the anus, throat, or penis.

6.  Syphilis 

Transmission: Spread through direct contact with syphilis sores (usually on the genitals, anus, or lips).

Symptoms by Stage:

  • Primary Syphilis: A small, firm, painless sore where the bacteria entered the body, typically on the penis, anus, or lips. Swollen lymph nodes may also be present.
  • Secondary Syphilis: A non-itchy skin rash, often found on the palms of the hands or soles of the feet, along with fatigue, sore throat, headache, and swollen lymph nodes.
  • Latent Syphilis: No symptoms but the infection remains in the body.
  • Tertiary Syphilis: Rare but severe complications, including damage to the heart, brain, and other organs, can occur if left untreated.

Note: Untreated syphilis can lead to serious complications, even years after transmission.

Prevention Measures

  • Safe Sex: Use of  condoms  or other barrier methods such as dental dams during oral sex to reduce the risk of transmission.
  • Regular Testing: Regular STD testing is important, especially for individuals with multiple sexual partners or unprotected sex.
  • Vaccination: Vaccines are available for  Hepatitis B  and  HPV , offering protection against these infections.
  • Open Communication: Talk to sexual partners about sexual health to ensure both parties take necessary preventive measures.

Important Note: Many STDs can be asymptomatic, so it’s crucial to practice safe sex, maintain healthy sexual habits, and get regular check-ups to protect your health and the health of your partners.
