Signs and Symptoms of Common STDs in Men

Many are quick to assume that if they had a sexually transmitted disease, they would know it. While most STDs do cause symptoms, many are easily mistaken for other conditions, and in some cases there are no symptoms at all. Understanding the risks and knowing the signs and symptoms of common STDs in men is crucial for any man who is sexually active.

Chlamydia

Chlamydia is a bacterial STD that is transmitted when one has anal, oral, or vaginal sex with someone who is infected with chlamydia. It is one of the most common sexually transmitted diseases in the United States, and according to the Centers for Disease Control and Prevention, 1,412,791 chlamydia infections were reported to the CDC in the United States in 2011.

Many people who become infected with chlamydia don’t ever display symptoms, while others only begin to display symptoms several weeks after becoming infected.

Some of the symptoms of chlamydia in men include:

  • pain when urinating
  • penile discharge
  • swollen testicles

Gonorrhea

Gonorrhea is a bacterial infection that can affect the anus, throat, or urethra. It is transmitted when one has anal, oral, and/or vaginal sex with a man or woman who has been infected. Most men with gonorrhea don’t display any symptoms at all. For those who do, symptoms include:

  • pain when urinating
  •  a green, white, or yellow discharge from the penis
  • swollen testicles

Hepatitis B

Hepatitis B is a form of hepatitis that is caused by the hepatitis B virus (HBV). Unlike other common STDs that can produce more obvious symptoms focused around the genitals that we tend to associate with STDs, hepatitis B causes a dangerous inflammation of the liver. One can contract hepatitis by coming into contact with the blood or bodily fluids of a person who is infected with the virus. 

Many people infected with hepatitis B will not display symptoms at all, and those who do often mistake symptoms for a cold or the flu. Even if a person has no symptoms, left untreated, the virus can continue to damage the liver. The symptoms of hepatitis B include:

  • loss of appetite
  • feeling lethargic
  • low-grade fever
  • muscle and joint pain and aches
  • nausea
  • vomiting
  • jaundice (yellow hue to the skin and dark urine)

Herpes (Simplex)

Herpes is a viral infection that is caused by the herpes simplex virus (HSV). Herpes may affect the mouth (oral herpes or HSV Type 1) or the genitals (genital herpes or HSV Type 2). Herpes is transmitted through direct contact with the mouth or genitals of a person who has been infected with the virus through sexual intercourse or oral sex and kissing.

The symptoms of herpes can be difficult to spot. Many people won’t have any symptoms at all, and those who do will develop blisters that are often mistaken for other skin conditions like pimples. Symptoms often occur between two days and two weeks after infection, and the initial outbreak can be severe. Common symptoms of herpes in men are:

  • tingling, itching, or burning of the skin in the area where the blisters will appear
  • blisters on the penis, testicles, on and around the anus, buttocks, or thighs
  • blisters on the lips, tongue, gums, and other parts of the body
  • aching muscles in the lower back, buttocks, thighs, or knees
  • swollen and sometimes tender lymph nodes in the groin
  • loss of appetite
  • fever
  • feeling unwell

Human Papillomavirus (HPV) 

HPV is a term used to refer to a group of viruses that comprises more than 150 strains. While most of these strains are quite harmless, 30 are considered potentially harmful and are classified as being either low-risk or high-risk strains. HPV is one of the most common sexually transmitted diseases today, with an estimated 80 to 90 percent of the female population being infected. According to the National Institute of Allergy and Infectious Diseases, there are approximately six million reported cases of HPV transmitted through sex every year, and currently there are at least 20 million people infected with HPV in the United States.

The low-risk strains may result in genital warts in some people, while in men the high-risk strains could lead to cancers of the anus, throat, and penis. HPV can be transmitted through skin-to-skin contact with a person who has been infected with the virus and is most commonly transmitted through anal, oral, or vaginal sex. Most men infected with HPV won’t have any symptoms at all. Symptoms of HPV in men may include:

  • genital warts (flat and flesh-colored or clusters of tiny bumps described as having a cauliflower appearance)
  • warts in the mouth or throat (spread through oral sex with an infected partner)

Unlike other STDs which can only be prevented through the use of condoms or by abstinence; HPV can be prevented with vaccines. There are two HPV vaccines that have been approved by the FDA: Gardasil and Cervarix. They are both effective in the prevention of HPV types 16 and 18 that are high risk and responsible for causing most cervical cancers (70 percent) and types 6 and 11 that cause over 90 percent of genital warts. Though originally recommended only for females age 9 to 26, Gardasil has now also been licensed for use in boys and men age 9 to 26 to prevent genital warts.

Syphilis

Syphilis is a bacterial STD that can be transmitted through anal, oral, or vaginal sex. This ancient disease is still quite prevalent today. Syphilis is considered one of the more serious STDs in men because of its link to HIV and the increased risk of developing HIV when infected with syphilis.

Syphilis has four different phases, each with its own set of symptoms. The symptoms of primary syphilis in men may include:

  • a very small, firm, and painless sore where the bacteria entered the body, usually on the penis, anus, or lips
  • swollen lymph nodes in the area near the sore

Symptoms of secondary syphilis may include:

  • a skin rash that does not itch, commonly found on the palms of the hands or soles of the feet
  • tiredness
  • sore throat
  • headache
  • swollen lymph nodes

Latent syphilis is the stage that occurs after the symptoms of secondary have stopped and the STD has gone untreated. Though rare, as few people actually enter the fourth stage even when left untreated, tertiary syphilis can cause serious complications, with damage to the heart, nervous system, brain, joints, and other parts of the body. Even several years after initial infection, syphilis, when it reaches this stage, can cause serious medical issues and death.

Prevention of STDs

As many people can be infected with an STD without experiencing any visible symptoms, practicing safe sex is crucial if you want to prevent STD infection. Though the only way to completely prevent an STD is abstinence from any type of sexual contact or contact with open sores and bodily fluids of an infected person, there are other ways to prevent STDs. Condoms during intercourse and dental dams or barriers during oral sex are proven effective when used correctly. And refraining from sex with multiple partners and instead opting for a monogamous sexual relationship can also help to prevent STDs.
