STI Facts: Gonorrhoea

Gonorrhoea is a sexually transmitted infection (STI) also known as ‘the clap’. It is caused by a bacteria called Neisseria gonorrhoea. Gonorrhoea is a bacteria that infects the penis, cervix, anus and throat.

How do you get gonorrhoea?

Gonorrhoea is passed on by unprotected sex with an infected person. This includes vaginal, oral and anal sex. Pregnant women can pass on gonorrhoea to their baby during birth which can cause blindness.

How do I know if I have gonorrhoea?

  • Most women and girls have no symptoms at all. Some may notice unusual discharge from their vagina. 
  • In men the most common symptom is a discharge from the penis, which usually is obvious, burning, and comes on quickly.
  • Men and women can also get a sore throat and discharge from their rectum after oral or anal sex. Most of the time, however, gonorrohoea of the cervix, anus or throat is asymptomatic—i.e. you have it without knowing.
  • A simple urine test and/or swab is all that's required to be tested for gonorrhoea.

How do I get treated for gonorrhoea?

Gonorrhoea is treated with antibiotics. The antibiotic chosen will be determined by whether your infection has been caught in the UK or elsewhere. Unfortunately, today there is great concern about antibiotic resistance in gonorrhoea because of inappropriate antibiotic usage so it is important to get adequately treated in a specialist clinic.

What would happen if I do not get treated for gonorrhoea?

  • If treated early, gonorrhoea is unlikely to cause significant long-term issues.
  • In men, gonorrhoea can cause a very painful infection in the testicles and the prostate gland which has the potential to cause infertility.

Gonorrhoea complications

Rarely, gonorrhoea can spread through the blood stream causing infections in other parts of the body. These include: inflammation and swelling of the joints and tendons, skin irritation and redness, inflammation around the brain and spinal cord (meningitis) or the heart, which can be life threatening.

How can I protect myself from getting gonorrhoea?

Anyone who has sex is at risk of getting STIs including gonorrhoea. At Marie Stopes, we recommend:

  • Always use condoms or dams and a water-based lubricant when having sex, even oral sex.
  • If in a long term relationship, ensure each partner has been tested before stopping condom use, and that neither of you has other partners.
  • Have regular STI checks.
  • Discuss STIs with your partner, even when it is difficult to talk about. Your partner will appreciate your honesty and that you don’t want to infect him/her. You have the right to know if they are infected too.
