Sexually Transmitted Infections
Sexually transmitted infections (STIs) are passed from one person to another through unprotected sex or genital contact.
Some STIs have no symptoms and if left untreated can lead to more serious health problems like infertility. Most STIs can be treated and cured when they are caught early enough.
- Unusual discharge from the penis or vagina which may smell unpleasant
- Lumps of blisters around the genitals or anus
- Pain when passing urine
- Pain and/or bleeding after sex
- Pain in the testicles or lower tummy
STIs include syphilis, HIV, gonorrhoea, genital warts, chlamydia and genital herpes.
