What is hypospadias?

In hypospadias, the opening of a boy’s urethra (through which both urine and semen pass) is located on the underside of the penis rather than at the tip. This condition, which is present at birth, affects about one in 200 boys. While very mild forms of hypospadias may not interfere with urinary or reproductive function, most boys with the condition will require surgery. When treated by experienced pediatric urologic surgeons, the outlook for infants who undergo this operation is extremely good: In most instances, they make a full recovery and have a normal-looking, fully functional penis within about six months.

If your child requires surgical repair of hypospadias, they should be treated by an experienced pediatric urologic surgeon in a multidisciplinary setting with access to specialists from several different disciplines. Boston Children’s Hospital is a destination for babies with complex hypospadias that requires specialized care, as well as boys who have previously undergone unsuccessful hypospadias repair elsewhere. We take a standardized approach to surgical repair, so you can be confident that your child will receive the same exceptional treatment no matter which of our skilled pediatric surgeons treats him.

What are the symptoms of hypospadias?

In hypospadias, the urethral opening can be located at any point along the underside of the penis. The location of the opening determines the severity of the condition:

  • Anterior (distal) hypospadias: The urethral opening is located near the tip of the penis. This is the mildest form of hypospadias, occurring in about 50 percent of cases.
  • Middle hypospadias: The opening is located midway up the penis. This accounts for about 30 percent of cases.
  • Posterior (proximal) hypospadias: The opening develops at a boy’s scrotum or perineum. This is the most severe form of the condition, and occurs in 20 percent of cases.

Other signs of hypospadias include:

  • downward urinary spray (in older boys with more severe hypospadias, this may mean they have to sit down to urinate)
  • downward curve of the penis, called chordee
  • “hooded” appearance to the penis, caused by extra foreskin along the top side
  • abnormal appearance of the tip of the penis (the glans)

In some cases, boys born with hypospadias may also have undescended testicles, inguinal hernias, or both.

Hypospadias doesn’t cause physical pain or block urination, but left untreated, more severe forms can interfere with sexual intercourse in adulthood.
