Disease: Hypospadias


    Hypospadias (hi-poe-SPAY-dee-us) is a birth defect (congenital condition) in which the opening of the urethra is on the underside of the penis instead of at the tip. The urethra is the tube through which urine drains from your bladder and exits your body.

    Hypospadias is common and doesn't cause difficulty in caring for your infant. Surgery usually restores the normal appearance of your child's penis. With successful treatment of hypospadias, most males can have normal urination and reproduction.

    In hypospadias, the opening of the urethra is located on the underside of the penis instead of at the tip. In most cases, the opening of the urethra is within the head of the penis. Less often, the opening is at the middle or the base of the penis. Rarely, the opening is in or beneath the scrotum.

    Signs and symptoms of hypospadias may include:

    • Opening of the urethra at a location other than the tip of the penis
    • Downward curve of the penis (chordee)
    • Hooded appearance of the penis because only the top half of the penis is covered by foreskin
    • Abnormal spraying during urination

    When to see a doctor

    Most infants with hypospadias are diagnosed soon after birth while still in the hospital. However, slight displacement of the urethral opening may be subtle and more difficult to identify. Talk to your doctor if you have concerns about the appearance of your child's penis or if there are problems with urination.

    Hypospadias is present at birth (congenital). As the penis develops in a male fetus, certain hormones stimulate the formation of the urethra and foreskin. Hypospadias results when a malfunction occurs in the action of these hormones, causing the urethra to develop abnormally.

    In most cases, the exact cause of hypospadias is unknown. Sometimes, hypospadias is genetic, but environment also may play a role.

    Your child's pediatrician can diagnose hypospadias based on a physical exam. He or she will likely refer you to a surgeon who specializes in genital and urinary conditions (pediatric urologist) for further evaluation. Medical centers with specialty teams can help you evaluate options and can provide expert treatment.

    When the opening of the urethra is abnormal and the testicles cannot be felt on exam, the genitals may be difficult to identify as clearly male or female (ambiguous genitalia). In this case, further evaluation with a multidisciplinary team is recommended.

    If hypospadias is not treated, it can result in:

    • Abnormal appearance of the penis
    • Problems learning to use a toilet
    • Abnormal curvature of the penis with erection
    • Problems with impaired ejaculation

    Risk factors

    Although the cause of hypospadias is usually unknown, these factors may be associated with the condition:

    • Family history. This condition is more common in infants with a family history of hypospadias.
    • Genetics. Certain gene variations may play a role in disruption of the hormones that stimulate formation of the male genitals.
    • Maternal age over 35. Some research suggests that there may be an increased risk of hypospadias in infant males born to women older than 35 years.
    • Exposure to certain substances during pregnancy. There is some speculation about an association between hypospadias and a mother's exposure to certain hormones or certain compounds such as pesticides or industrial chemicals, but further studies are needed to confirm this.
