Sexually transmitted infections are far more common than most men realize. Many STIs cause mild symptoms or none at all, but untreated infections can lead to serious long-term health problems for both men and their partners.
At KS Women’s Health Clinic, we believe sexual health is part of total health. Here is what every man should know about STIs, including how they’re spread, and when to get tested.

What Are STIs and How Do Men Get Them
STIs are infections passed from one person to another through sexual contact. They are caused by bacteria, viruses, or parasites.
Common STIs in men include:
- chlamydia
- gonorrhea
- syphilis
- genital herpes
- HPV
- HIV
- trichomoniasis
Sexually transmitted infections can spread through:
- vaginal, anal, or oral sex
- skin-to-skin contact with infected areas, such as with herpes or HPV
- sharing needles or other equipment
- blood contact in rare cases
However, you do not need penetration to get an STI. Skin-to-skin contact is often enough.
Symptoms of STIs in Men
Some men notice symptoms. However, many do not.
Possible symptoms include:
- burning or pain when urinating
- unusual discharge from the penis
- sores, bumps, or blisters on the genitals or mouth
- genital itching or irritation
- pain or swelling in the testicles
- rectal pain or discharge
The most important point: many STIs cause no symptoms at all. Therefore, you can have an infection and pass it to someone else without realizing it.
Can Men Have an STI Without Symptoms
Yes, and this is extremely common. Infections such as chlamydia, gonorrhea, and HPV often cause no symptoms in men, especially early on. As a result, testing is the only way to know for sure.
Untreated infections can lead to:
- prostate or testicular infections
- infertility
- chronic pelvic or abdominal pain
- increased risk of transmitting HIV
Early testing prevents these problems.
How STIs Are Diagnosed and Treated
Testing is private and simple. Your provider may use:
- a urine sample
- a swab from the urethra, throat, or rectum
- a blood test
Treatment depends on the infection type.
Bacterial STIs
Chlamydia, gonorrhea, syphilis, and trichomoniasis are usually treated with antibiotics.
Viral STIs
Herpes, HPV, and HIV are not curable, but antiviral medications help reduce symptoms and transmission risk. If you test positive, your provider will explain how to protect your partner and prevent reinfection.
Can STIs Cause Long-Term Problems
Yes. Untreated STIs can lead to serious complications, including:
- infertility
- chronic pelvic pain
- increased risk of certain cancers, such as HPV related cancers
- nerve, heart, or brain damage from untreated syphilis
Most long-term issues can be avoided with early diagnosis and proper treatment.
Should My Partner Be Tested Too
Absolutely. STIs often pass back and forth between partners. Both partners need testing and treatment at the same time to prevent reinfection.
At KS Women’s Health Clinic, we offer testing and treatment for both men and women and support couples who want to improve their sexual health together.
How Men Can Prevent STIs
- use condoms consistently and correctly
- get tested regularly
- avoid sharing needles or equipment
- limit the number of sexual partners
- talk openly with partners about sexual health
- get vaccinated for HPV and Hepatitis B
Prevention is simple. It is also highly effective.
The Takeaway
STIs are common, and many are symptom-free. According to the Centers for Disease Control and Prevention, many sexually transmitted infections in men can be asymptomatic, which is why regular testing and prevention strategies are important. The good news is that they are easy to test for and treat. Protecting your sexual health is one of the best ways to protect your overall health. Explore our men’s health services here.
