Cystitis is inflammation of the urinary bladder usually caused by bacteria. Cystitis is not a sexually transmitted disease, but sexual intercourse does increase the risk of cystitis (bladder infection) in women.

Is Cystitis a sexually transmitted infection?

Cystitis means soreness and swelling (inflammation) of the bladder. It is usually caused by a bladder infection and is not a sexually transmitted infection (STI). Cystitis can occur at any age, in anyone, but is more common in people with a vagina who are sexually active or pregnant.

How can Cystitis be transmitted?

UTIs typically occur when bacteria outside the body enter the urinary tract through the urethra and begin to multiply. Most cases of cystitis are caused by a type of Escherichia coli (E. coli) bacteria. Bacterial bladder infections may occur in women as a result of sexual intercourse.

Can a man catch Cystitis off a woman?

Although you can’t pass on Cystitis, you may wish to tell your partner if you are experiencing discomfort that means you don’t want to have sex. If sex is triggering your Cystitis, you may find it helpful to talk to your partner about how you feel and what you can do to reduce the risk of infection.

Can condoms cause cystitis?

Contraception. Using condoms is not known to prevent cystitis and using diaphragms and spermicides can actually make cystitis more likely because the normal mucus around the vaginal area is altered: “good” bacteria are killed, leaving infectious bacteria to grow.
