Private Sexual Health (GUM) Clinic in London

Same Day STD and STI Testing with Expert Care

We are a trusted private sexual health clinic based on South Kensington in London. We help men and women of all ages with testing, advice and treatment for all types of STDs and STIs.

We know that sexual health is a private and personal matter, and it can often be uncomfortable to discuss. As a result, many people choose to avoid visiting a doctor, opting instead for home testing kits or pharmacy-based solutions. That’s why some people choose home testing kits or go to the pharmacy instead of seeing a doctor. While those options might seem quick and private, they can lead to problems — like inaccurate results, delays in treatment, or no real medical advice.

At our private sexual health clinic, we take a different approach. All of our packages include in-person consultations, physical examinations, prescriptions and follow-up visits with highly experienced sexual health specialists. With decades of clinical expertise, our team is committed to delivering accurate diagnosis, treatment and care.

If you're in London and looking for a private sexual health clinic that offers same-day STD testing, we're here to help.

We only use laboratory-based PCR testing, which is considered the gold standard for detecting infections. This ensures fast, reliable results that guide the most suitable treatment options for your condition. All of our testing services are fully confidential. We never share your results with anyone. For complete discretion, you may use a pseudonym and choose to pay in cash.

Common Symptoms of STDs in Men and Women

Sexually transmitted diseases (STDs) can affect anyone, and many infections show similar symptoms in both men and women. However, some signs may differ by gender. Recognizing these symptoms early can help you get tested and treated quickly.

In Women:

• Unusual vaginal discharge (yellow, green, or foul-smelling)
• Pain or burning during urination
• Pain during sex
• Vaginal itching or irritation
• Lower abdominal or pelvic pain
• Bleeding between periods or after sex
• Sores, bumps, or blisters near the genitals, anus, or mouth
• Swollen glands in the groin
• Fever or flu-like symptoms (in some cases)

In Men:

• Unusual discharge from the penis (white, yellow, or green)
• Burning or pain when urinating
• Pain or swelling in the testicles
• Itching or irritation inside the penis
• Sores, blisters, or bumps near the genitals, anus, or mouth
• Pain during ejaculation or sex
• Swollen glands in the groin
• Fever, body aches, or fatigue (in some cases)
  
  

Reminder: Some STDs cause no symptoms at all. Regular testing is the only way to know for sure and protect your health and your partner’s.

Treatment for Common STDs

Most sexually transmitted diseases (STDs) can be treated—and many can be cured—especially when found early. The type of treatment depends on the infection, and both partners should be treated to prevent reinfection.

Bacterial STDs (Often Curable):

• Chlamydia – Treated with antibiotics (usually azithromycin or doxycycline)
• Gonorrhoea – Treated with antibiotics (often a single injection or oral medication)
• Syphilis – Treated with penicillin injections (early stages)
• Trichomonas – Treated with oral antibiotics like metronidazole or tinidazole
• Bacterial Vaginosis (BV) – Treated with antibiotics (metronidazole or clindamycin)
  
  

Viral STDs (Manageable, Sometimes Curable):

• HIV – Not curable, but controlled with daily antiretroviral therapy (ART)
• Herpes (HSV-1 and HSV-2) – No cure, but managed with antiviral medications (acyclovir, valacyclovir)
• Hepatitis B – No cure, but managed with antiviral drugs; vaccine available to prevent infection
• Hepatitis C – Often curable with antiviral treatment (DAAs)
• HPV (Human Papillomavirus) – No cure for the virus, but warts can be treated and most cases clear on their own; vaccines available for prevention
  
  

Important Notes:

• Always take the full course of medication, even if symptoms go away.
• Inform your sexual partners so they can get tested and treated.
• Avoid sex until your treatment is complete and your doctor says it’s safe.
• Regular follow-up testing may be needed, especially for HIV, syphilis, and hepatitis.
  
  

Expert Advice for Maintaining Good Sexual Health

Taking care of your sexual health is important for your whole body and mind. It means protecting yourself from infections, making smart choices, and having safe and respectful relationships.

Get tested for sexually transmitted infections (STIs) regularly, even if you feel fine. Many STIs do not show symptoms but can still harm your health. Using condoms or dental dams during sex helps protect you from most STIs, including HIV.

Talk openly with your partner about testing, protection, and your sexual history. Good communication helps build trust and keeps both of you safe. You should also get vaccines for HPV and Hepatitis B. These vaccines prevent serious diseases like cancer and liver problems.

Watch for any signs like pain, sores, discharge, or itching. If you notice anything unusual, see a doctor right away. Treating infections early can stop them from getting worse or spreading to others.

Avoid risky choices like having many partners or having sex while drunk or high. These situations can make it harder to stay safe.

Remember, sexual health also means feeling safe, respected, and happy in your relationships. If you ever feel unsure or uncomfortable, talk to a doctor or counselor. Staying informed and asking questions is a smart way to protect yourself and your health.
