The HUG Gynecology Division informs, screens, and treats women and girls who have sexually transmitted diseases (STDs).

If detected in time, most STDs are cured. Untreated, they can have serious consequences, such as infertility, extrauterine pregnancies, and chronic pain, and they significantly increase the risk of HIV infection. In Switzerland, it is estimated that more than 50% of cases of chlamydia and gonorrhea affect women 15 to 24 years of age.

Sexually transmitted diseases: are you affected?

STDs are infections that are transmitted sexually (vaginal, oral, anal). Some are also transmitted in other ways (blood, saliva, from mother to child during pregnancy, childbirth, or breastfeeding).

STDs can be caused by bacteria, viruses, fungi, or parasites.

What are the symptoms of STDs? 

  • Itching, irritation, redness, burning, bumps, or growths on the genitals.
  • Unusual and/or smelly vaginal discharge.
  • Burning when urinating.
  • Unusual blood loss, even if not significant (outside of menstrual periods).
  • Diffuse pain in the lower abdomen, which is not due to menstrual periods.
  • Pain and burning during sexual intercourse.
  • Flu-like symptoms after sexual intercourse without a condom.

When should you see a doctor?

If you have any of these symptoms or you have had unprotected sex (without a condom), contact your gynecologist or the Gynecology Office.

Be aware that you can have an STD without having any specific symptoms.

What happens at the consultation?

The gynecologist asks you questions to learn about your lifestyle and risk factors for exposure to infection. During the consultation, you can ask your questions.

Together, you will develop the care pathway: clinical examinations, screening tests (blood) and collection of samples, as well as follow-up and treatment.

If you were accidentally exposed or you have concerns, the gynecologist will implement immediate post-exposure care.

How to prevent and avoid STDs?

  • Use a condom (male or female) during any vaginal, anal, or oral penetration.
  • See a physician right away in case of itching, discharge, genital pain, or flu-like symptoms after unprotected sex.
  • Get vaccinated against diseases such as hepatitis B, HPV (human papillomavirus) for girls.

Get screened if you have taken risks or if you have symptoms of infection.
