These are conditions usually caused by infections that can affect the genital area and urinary system.
Some infections are caught from another person, usually during sex.

Other cases are caused when organisms (bacteria or yeast), which are usually present in small numbers, overgrow and cause symptoms.

Some genitourinary (GU) diseases are caused by bacteria that do not cause problems in their usual home in the body, but do if they get into another place.

These diseases are often managed best at a genitourinary medicine (GUM) or sexual health clinic.
