Sexually transmitted diseases in men

Sexually transmitted diseases (STDs) affect tens of millions of people in the United States, and there are almost 20 million new infections each year, according to the Centers for Disease Control and Prevention (CDC). Men may not realize they’re infected, because many infected men have no symptoms. However, that doesn’t mean that STDs aren’t affecting their health.

Not all STDs have symptoms, but when they occur in men, they can include:

  • pain or burning during urination
  • a need to urinate more frequently
  • pain during ejaculation
  • abnormal discharge from the penis, particularly colored or foul-smelling discharge
  • bumps, blisters, or sores on the penis or genitals

Common STDs in men

The most common STDs affecting men include:

Chlamydia

  • Symptoms: Symptoms include pain when urinating, pain in the lower abdomen, and penile discharge.
  • Prevalence: In 2015, there were 478,981 reported cases in men (or 305.2 per 100,000 men) in the United States.
  • Keep in mind: Most people with chlamydia don’t experience symptoms. Because of this, experts believe that many cases go unreported.
  • Treatment: Chlamydia is treated with an antibiotic regimen, and you can usually recover from a case within a week or so.

Genital herpes

  • Symptoms: Symptoms include itching and pain, tiny fluid-filled or red-colored bumps, and ulcers that may eventually leave scabs.
  • Prevalence: Around 15 percent of people in the United States have genital herpes. It affects over 500 million people worldwide.
  • Keep in mind: It’s possible to spread herpes even if you don’t have sores or symptoms.
  • Treatment: Antiviral medicines, such as acyclovir and valacyclovir, can treat outbreaks. However, no cure exists for herpes.

Genital warts and human papillomavirus (HPV)

  • Symptoms: Symptoms include small areas of swelling around the penis (in the case of genital warts), cauliflower-shaped warts, and itching around the penis.
  • Prevalence: Around 45 percent of men in the United States currently have human papillomavirus (HPV), which can sometimes cause genital warts. It affects 79 million Americans overall.
  • Keep in mind: There is currently no recommended HPV test for men.
  • Treatment: Genital warts are usually treated with a medication that’s applied to the warts. However, they can also be removed surgically if medication doesn’t work.

Gonorrhea

  • Symptoms: Symptoms include burning during urination, yellow or green discharge, and pain in the testicles.
  • Prevalence: In 2015, there were 395,216 reported cases (or 123.9 per 100,000 people) in the United States.
  • Keep in mind: If left untreated, a gonorrhea infection can increase a person’s chances of getting HIV.
  • Treatment: Gonorrhea is usually treated with a regimen of two medications, or dual therapy.

HIV

  • Symptoms: Symptoms include fever, rash, sore throat, and swollen lymph nodes. Symptoms worsen as HIV infection progresses.
  • Prevalence: Over 1.2 million people in the United States are currently infected with HIV.
  • Keep in mind: HIV is thought to occur more frequently in men who have sex with men because of the additional risk of infection from anal sex.
  • Treatment: HIV isn’t curable, but it can be treated by several classes of drugs that stop the virus from copying itself and taking over body cells.

Trichomoniasis (Trich)

  • Symptoms: Symptoms are rare in men, but can include itching on the penis, painful urination, and penile discharge.
  • Prevalence: Over 3 million people in the United States have the infection.
  • Keep in mind: Around 20 percent of people with trich are re-infected within three months of being treated.
  • Treatment: Trich is easy to cure and is usually treated with one dose of antibiotics.

Prevention for men

STDs can affect any man who is sexually active, regardless of his age, race, or sexual orientation. However, many STDs are highly preventable.

Abstinence is the only foolproof method to protect against STDs. However, by being aware of changes in your body and practicing safer sex, you can protect yourself and your partners. Consistently practicing safe sex makes the transmission of an infection less likely.

STDs can be transmitted through vaginal, oral, and anal sex. It’s important to practice safe sex during all sexual activities. Condoms can be used for vaginal, oral, and anal sex. Dental dams and other barriers can be used for any type of oral sex.

Many people believe that oral sex is risk-free. However, numerous STDs can be transmitted during oral sex, including syphilis, herpes, and gonorrhea.

Some STDs spread more easily during anal sex. These STDs may be more common in men who have sex with men. No matter your sexual orientation, you should take good care of your sexual health by always having safe sex and being regularly tested for STDs.

Getting tested for STDs

Regular STD testing is a good idea if you’re not in a long-term, mutually monogamous relationship. Although safe sex is good at reducing STD transmission, it’s not perfect. Regular testing is the best way to take charge of your sexual health.

It’s important to ask your doctor for STD testing. You may assume that your doctor will screen you for STDs at your annual physical exam, but if you don’t ask, you may not be tested. Even if your doctor does test you, you may not be given every test you want—there aren’t good screening tests for every STD. Ask your doctor at every physical exactly what you’re being tested for and why.

If you suspect you have an STD (and you live in the United States), find a testing center near you at https://gettested.cdc.gov. Contact them as soon as you can to avoid any long-term effects of a potential STD.

You should request STD tests at every physical, but you should also visit a testing center any time you’ve had unprotected sex (especially if you believe your partner may have an STD). Test results are usually available in a few days to a week. Some may require simple urine samples, but others may require blood tests.

While women can get a Pap smear and HPV test, there currently isn’t an HPV screening test for men. Some types of HPV cause no symptoms, while others cause genital warts. Talk with your doctor if you notice any bumps or warts.

To determine what STD tests you need, talk to your doctor honestly about your sexual risk. Tell your doctor if you think you might have been exposed to an STD, or if you’re just coming in for preventive screening.

It’s also good to mention whether you practice receptive anal sex. Anal sex can put you at risk of certain STDs that require special testing. For example, an anal Pap smear can be used to test for signs of HPV-related anal cancers.

Finally, tell your doctor if you reliably practice safe sex for oral, anal, and vaginal sex. This can help your doctor assess your risk for various infections.

Complications of STDS

Complications of STDs can be minor, such as inflammation of the eyes and pain in the pelvic region.

Other complications can be life-threatening or otherwise cause lasting harm, such as:

  • heart disease
  • infertility
  • arthritis
  • HPV-related cancers of the cervix and rectum

Treatment for STDs

Treatment for STDs varies based on whether the STD is bacterial or viral.

Bacterial STDs, such as gonorrhea, chlamydia, or syphilis, can be treated with antibiotics. These may include metronidazole or tinidazole (for trichomoniasis).

Viral STDs, such as herpes, must be treated with antiviral drugs. Sometimes, these drugs must be taken daily to keep the infection from breaking out again. This is known as suppressive therapy.

HPV cannot be cured completely, but getting vaccinated can help you substantially lower your risk of contracting HPV or an HPV-related STD.

A pre-exposure prophylaxis (PrEP) pill can help you avoid getting HIV if your doctor believes you’re at risk. The pill consists of two drugs that fight HIV if it enters your body and treat any symptoms or complications. This pill must be taken every day. It can be a successful method of preventing HIV along with other safe sex habits.

Takeaway

Sexually transmitted diseases are more common than you might think. Whenever you see any symptoms of an STD or believe you may have become infected, get tested. See your doctor as soon as possible to avoid any pain or discomfort associated with your symptoms.

Be honest with your doctor when describing your sexual history and your symptoms. Talking about your sex life or getting an STD may feel too personal or uncomfortable to share. But learning about an STD early, taking preventive measures, and getting treatment quickly will help prevent long-term consequences to your health as well as allow you to enjoy a healthier sex life.
