The risk of contracting HIV, gonorrhea, syphilis, and genital herpes is higher for homosexual people, especially for men who have sex with men. Dr. Fuzayloff, an experienced and LGBT culture–trained STD doctor from NYC, will answer the most commonly asked questions and questions relevant to the LGBT community here.
-
How is STD testing different for LGBT persons?
Testing recommendations for members of the LGBT community are different in the following ways:
- More frequent STD testing is necessary for most people for these reasons:
- Higher prevalence of STDs
- The type of sex practiced (rectal sex is 18 times riskier for HIV acquisition)
- More lifetime sex partners
- More casual sex
- Rectal and oral swabs for chlamydia and gonorrhea are often necessary
Both chlamydia and gonorrhea stay in the part of the body contacted during sex, so a negative test of one body part (e.g., the penis or vagina) does not rule out gonorrhea in another body part (e.g., the mouth or rectum). So, in addition to routine urine and vaginal swab tests, rectal and oral swab testing is necessary.
- Some STDs are preventable through vaccination, which is encouraged in the homosexual community
- Hepatitis A
- Hepatitis B
- HPV
-
How often should LGBT persons be tested for STDs?
STD testing frequency in the LGBT community depends on how active the person is:
- All sexually active gay, bisexual, and transgender persons should be tested at least once a year.
- Homosexual males who have multiple or anonymous partners should be tested every 3–6 months.
-
HIV/AIDS
Many men who have sex with men (MSM) are at higher risk of HIV infection—42% of all newly diagnosed HIV infections are in MSM.
How long after potential exposure should HIV testing be done?
Different types of HIV tests should be done at different times:
- The ultrasensitive HIV RNA PCR test used for early detection can be done 5 days after exposure
- The HIV RNA PCR test can be done 10 days after exposure
- The HIV fourth-generation test (Ab/Ag) can be done as early as 13 days after exposure
- The HIV third-generation test (Ab) can be done as early as 22 days after exposure
What reduces the chance of getting HIV?
The rate of HIV transmission has decreased because more people are following these practices, which are recommended:
- Safe sex
- Preexposure prophylaxis (PrEP) — effective as soon as 7 days after starting the medication
- Post-exposure prophylaxis (PEP)—should be initiated within 72 hours of risky exposure
-
Syphilis
The number of newly diagnosed syphilis cases is going up. This disease primarily occurs in men who have sex with men.
How long after potential exposure should syphilis testing be done?
Different types of tests need to be done at different times:
- RPR: 2–3 weeks after exposure
- VDRL: 3–6 weeks after exposure
- FTA-ABS: 3–4 weeks after exposure
- TPPA: 3–4 weeks after exposure
-
Gonorrhea
The prevalence of gonorrhea is increasing in men who have sex with men. An oral reservoir of gonorrhea and having unprotected oral sex may be the reason. Half of people with gonorrhea have chlamydia at the same time.
How is gonorrhea testing different?
Unlike other infections, after gonorrhea is acquired through physical contact with an infected person, it remains where the contact occurred. Therefore, even with a negative test of one body part, a person could have gonorrhea in another part of the body. Testing is needed of all parts of the body that came into contact with the infected person’s body and that are capable of being infected with gonorrhea.
Both males and females can have urine and urethral tests, while vaginal swab testing is, of course, done on females. If oral sex was involved in the suspected exposure, the person who “gave” oral sex should have throat swab testing. If anal sex was involved, the person who “received” it should have anal swab testing.

HSV-2, or “genital herpes”
Higher rates of HSV-2 infection are found in homosexual people. And herpes virus sores make people more susceptible to HIV infection.
Herpes testing types:
If you don’t have symptoms, only an IgG blood test can be done:
- 3 weeks after exposure: 50% accuracy
- 6 weeks after exposure: 70% accuracy
- 12 weeks after exposure: 92% accuracy
If you have symptoms:
- When the first blisters appear, a swab test can be done
- For a swab test to be done, a sample must be collected from a herpes lesion. The window of time to collect a sample is very short, so testing should not be delayed.
-
Who should get an anal Pap smear test?
There are no national guidelines regarding anal PAP smear testing. Some medical societies advise high-risk people who belong to one of these groups to this test:
- People who “receive” anal intercourse
- People with genital warts
- HIV-positive people
- Patients with immunosuppressive conditions or who are taking medication that suppresses the immune system
- People who have been diagnosed with high-risk HPV anywhere (e.g., vaginally)
For anyone whose anal Pap smear test is abnormal, a high-resolution anal anoscopy is recommended.
-
How often should an anal PAP smear be done?
Anal Pap smear recommendations for males:
- HIV negative: every 2–3 years
- HIV positive: yearly
