Gonorrhea is often symptomless - so you could catch it from someone who doesn’t know that they have it. If you have had unprotected sex you should get tested for STIs to make sure you are healthy.
The following symptoms are common in men:
needing to urinate frequently
burning duration or pain during urination
itching, bleeding or anal discharge (if you have caught gonorrhea during anal sex)
unusual penile discharge, which may be clear, milky, yellow or of a greenish colour
The symptoms of gonorrhea in women are not dissimilar and as with men, the infection often remains symptomless in women
When a gonorrhea infection remains untreated for a long time, it can cause an inflammation in your genital tract, which is called epididymitis. In the long term, this can lead to scarring and your sperm ducts can become blocked - which makes it difficult for sperm to flow to your penis. As a result, you may become less fertile or infertile. How commonly gonorrhea causes male infertility is not known.
