Phimosis

Also called Tight foreskin or Paraphimosis

Phimosis is when the foreskin is too tight to be pulled back over the head (glans) of the penis. It is normal in babies and young boys, and the foreskin usually loosens by itself with age. In older boys and men it can be caused by scarring, infection or skin conditions such as lichen sclerosus.

What it is

If it causes no problems, it usually does not need treatment. Steroid creams can help loosen the foreskin.

If it causes pain, infections or problems peeing, circumcision or other surgery may be offered.

Common signs

  • Being unable to pull the foreskin back
  • Redness, soreness or swelling
  • Pain when peeing or during erections
  • The foreskin ballooning when peeing
  • Repeated infections (balanitis)

How it is usually diagnosed

  • Examination of the penis

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • GP or urology notes
  • Prescriptions
  • Surgery notes

Questions to ask your doctor

  • Is this normal for my child's age?
  • Would a steroid cream help?
  • When would surgery be considered?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • A foreskin stuck behind the head of the penis with painful swelling (paraphimosis), or being unable to pee: get urgent help, call 112
