Living with Spina bifida-hypospadias syndrome

A rare condition present at birth that combines spina bifida in the lower back with hypospadias, a difference in the opening of the penis.

Understanding Spina bifida-hypospadias syndrome

Spina bifida-hypospadias syndrome is a rare condition that develops before birth and combines spina bifida in the lower back with glandular hypospadias.

Spina bifida means the spine didn't close fully. In hypospadias, the urine opening is on the underside of the penis. Some people also have other differences, such as extra fluid in the brain (hydrocephaly), a small mouth, a heart vessel that stays open, undescended testes, twisted intestines, rocker-bottom feet and extra hair. Signs begin during pregnancy, at birth or in infancy.

Signs & symptoms

GARD lists these among the most common features:

  • Spina bifida in the lower back
  • Hypospadias
  • Extra fluid in the brain (hydrocephaly)
  • Undescended testes
  • Heart vessel that stays open
  • Rocker-bottom feet

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.
