Yes. Our clinic provides testing, diagnosis, and treatment for these major sexually transmitted infections.

Please feel free to speak with our staff.Our staff, who have specialized knowledge of STIs, will ask about your risk and situation and guide you to the appropriate tests. If you are unsure, please don’t hesitate to call us:

• Shinjuku Clinic: 03-5337-6611
• Tokyo Clinic: 03-5255-6611

• Regular test: Results can be checked online in 2–3 days.
• Same day testing: Results come in about 20 minutes to 1 hour—recommended for those who want results the same day.

Note: Some same day testing may be slightly less accurate compared to regular tests.

• For men planning a urine test: please avoid urination until your visit.
• For women doing a vaginal discharge test: do not wash inside the vagina.

There are no restrictions on eating or drinking otherwise.

If you have taken antibiotics within the past week, it may affect tests for chlamydia, gonorrhea, mycoplasma, ureaplasma, etc. Please inform us in advance.

• Regular tests for chlamydia and gonorrhea can be performed during your period without any problems.
• Same-day chlamydia and gonorrhea tests, as well as vaginal discharge tests (for candida, trichomonas, and general bacteria), may be affected by menstrual blood and could result in less accurate results.

If you have symptoms, we recommend visiting the clinic even during your period. Please consult with us first.

Yes. Please let us know in advance if you have a history of syphilis.
For those with a past syphilis infection, we will guide you to the regular test (TP / RPR) rather than the same day testing.
The same day syphilis test only checks TP antibodies. If you have had syphilis before, TP antibodies may remain positive even after being cured, so that test cannot determine current infection in such cases.
If you wish to confirm post-treatment or cure, please ask our staff. We can guide you to a different testing method.

The “blood draw” is performed by qualified medical staff.
Self collection applies to urine (men), vaginal swab (women), or oral rinse. All of these are simple to collect, so no worries.
If a woman is uneasy collecting a vaginal swab by herself, a doctor can do it upon request.

We can draw blood while you are lying down. Please inform staff if you are anxious. The amount of blood required depends on the test items, but it is typically less than the amount used in standard health checkups.

Yes. The needle, holder, alcohol swab, bandage, gloves, etc., are all brand new and disposable. There is absolutely no risk of infection from the blood draw.

Chlamydia is treated with oral medication, while gonorrhea is treated with an injection. The gonorrhea injection is administered in the arm.

Treatment involves inserting medication directly into the vagina rather than taking oral medication. Depending on your condition, a cream may also be prescribed.

Yes. Our clinic treats condyloma using either a cream or liquid nitrogen. Please note that laser treatment is not available.

Treatment is done with oral medication or injections. Syphilis injections are given in the buttocks.
Treatment duration for syphilis may vary depending on symptom progression.

■ Early stage (within 1 year of infection)

Oral medication	: 2 weeks
Injection	: 1 dose

■ Late stage (unknown infection period)

Oral medication	: 4 weeks
Injection	: 3 doses (once per week for 3 weeks)

Pus typically stops within 1–2 days after the injection. Pain during urination gradually decreases. Even if symptoms disappear, you can still transmit the infection to others. Please refrain from sexual activity for at least one week.
Although symptoms generally resolve shortly after treatment, we recommend a follow-up test for confirmation of cure at least 2 weeks later.

• Chlamydia: After a follow-up test confirms a negative result.
• Gonorrhea: At least 7 days after the injection, but it is recommended to confirm a negative result with a follow-up test first.
  ( Throat chlamydia or gonorrhea may have no symptoms and may not be cured with a single treatment. Always take a follow-up test.)
• Syphilis: From 4 weeks after starting treatment. (Infectivity usually ends in 4 weeks, but treatment duration may exceed 4 weeks depending on symptoms.)
• Genital herpes: Refrain from sexual activity while symptoms are present.
• Condyloma (genital warts): Refrain from sexual activity while symptoms are present.

Yes. Our clinic provides PrEP, PEP, and DoxyPEP for prevention of HIV and other STIs.

PrEP is one method to prevent HIV infection.
By taking the medication correctly before sexual activity, it can reduce the risk of HIV infection from sex by 99%.
➡ For more details, please see: Prevent HIV with PrEP

PEP is one method to prevent HIV infection.
If you have had an event or activity with a risk of HIV exposure, taking PEP after the exposure—within 72 hours (3 days)—can help prevent the virus from establishing an infection in your body.
➡ For more details, please see: Concerned About Possible HIV Exposure? (PEP)

DoxyPEP is a method used to prevent infections such as chlamydia, syphilis, and gonorrhea. By taking the medication within 72 hours after sexual activity, it can reduce the risk of these infections.
The preventive effects are approximately:

• Chlamydia: 70-90％
• Syphilis: 70-90％
• Gonorrhea: around50％

Chlamydia and gonorrhea are infections that are primarily transmitted through sexual activity. Even without penetrative sex, they can be transmitted through oral sex or kissing.

Sexually transmitted infections (STIs) are primarily transmitted through sexual activity. They cannot be transmitted without close contact involving bodily fluids or mucous membranes. However, warts, blisters, or other lesions can contain a high concentration of pathogens, so please avoid touching these areas.

Syphilis is not transmitted without contact between mucous membranes, such as through kissing or sexual activity. There is no need to restrict everyday activities like eating. However, if you are concerned, you may choose to avoid actions that make you uncomfortable until treatment is completed.

Gonorrhea bacteria are weak and die within a few hours outside the body. Therefore, washing and thoroughly drying your underwear is sufficient.

Chlamydia often shows no symptoms and can persist for a long time in the genitals or throat. Unless you and your partner have been tested regularly, it is usually impossible to determine who was infected first. When infection occurs, it is important that both partners receive treatment and complete a follow-up test to confirm that the infection has been fully cured.

Treatment is necessary if genital warts cause symptoms. If your partner does not have any symptoms, an examination is not required. However, because the incubation period can be long, symptoms may appear up to 8 months later. If symptoms do develop, your partner should seek medical attention immediately.

In general, STIs do not heal on their own. Even if symptoms disappear, the pathogens remain in the body and the infection can progress if left untreated. If you have symptoms or have been exposed, please make sure to get tested and treated.

Most STIs can be cured if medications are taken as directed by a doctor.
Some infections, such as HIV or genital warts (condyloma acuminatum), cannot be completely cured, but proper treatment can prevent the condition from worsening and reduce the risk of transmission to others.
If you have engaged in high-risk activities, we strongly recommend getting tested as soon as possible.

Even if you are infected with HIV, proper treatment means it is not a death sentence.While current medicine cannot completely eliminate the virus from the body, taking medication consistently allows you to maintain your health.
For example, a person who starts treatment at age 20 can expect an average life expectancy of 78 years—almost the same as someone who is not infected with HIV.

Chlamydia can sometimes be resistant to antibiotics, and treatment may not always be effective depending on the medication used. Therefore, a follow-up test to confirm that the infection has been cured is necessary. Please take the test at least two weeks after finishing your medication and inform the staff if your symptoms have not improved.
If your follow-up test is negative but symptoms persist, it may indicate another bacterial infection, so please consult a doctor.

No, syphilis can be completely cured with treatment.
What remains in the blood is called the TP antibody, which does not cause any health problems even if it persists.
However, the TP antibody is what is tested when checking for syphilis, so people who have had a past infection may still test positive even after being cured. In such cases, alternative testing methods may be used depending on the situation.

STIs such as chlamydia, gonorrhea, and syphilis do not recur if treated correctly. However, reinfection is possible, so it’s important to practice prevention.
Some conditions, such as herpes, bacterial vaginosis, and candidiasis, can recur. Treatment can help control symptoms, so if a recurrence occurs, please seek medical attention promptly.
