In health care the term STI and STD are used interchangeably. A sexually transmitted infection (STI) may not develop into a disease. You may carry the infection, and even be contagious, but it may never lead to any symptoms or cause you real health problems. However, there are certain infections which can lead into disease for example, undiagnosed chlamydia or Gonorrhoea infection can lead to pelvic inflammatory disease if you are not tested and treated on time.

You can pass on sexual transmitted infection if you’re giving or receiving oral sex. The risk increases if either of you has sores or cuts around the mouth, genitals or anus. STIs that can be passed on through oral sex include:

  • Chlamydia
  • Herpes type 1 and type 2
  • Genital warts
  • Gonorrhoea
  • Hepatitis A, Hepatitis B and Hepatitis C
  • HIV
  • Syphilis

This is very dependent on your risks, behaviour and if your sexual contact was with a non regular partner, unprotected or protected (BASHH 2020). As a minimum Citydoc recommends a HIV, Syphilis, chlamydia and Gonorrhoea test and our specialist nurse will discuss this with you at your appointment.

One of our specialist nurses will contact you. Citydoc provides treatment nationwide for chlamydia. In our prestigious London clinics we offer treatment for chlamydia and Gonorrhoea. If any of your blood results are detected such as HIV or Hepatitis B our medical team will support and refer into appropriate care.

We are unable to offer sexual health screening for under 18’s please refer to your local GUM service and GP.

We recommend a HIV test if you have taken risk in particular unprotected anal and or vaginal sex. The majority of people will be well with no symptoms for many years this is known as asymptomatic HIV infection. With time however, the immune system becomes weaker and is incapable of fighting illnesses.

Citydoc can provide sexual health screen if you are pregnant and have no symptoms. We are unable to provide HPV screening or cryotherapy during your pregnancy. We advise you to check with your midwife and or GP before screening.

We obtain consent from you first if you wish for your results to be shared with your GP.
