Cerebral palsy is a rare condition following injury of the developing brain and including nonprogressive neurological disorders, spasticity, intellectual impairment and others. Boys with cerebral palsy have a high incidence of undescended testis. Although the motives for treatment (infertility, cancer prevention, psychological aspects, testicular torsion) are not different in boys without neurological impairment, the decision-making process in boys with cerebral palsy is very difficult. Besides medical and surgical arguments the discussion involves challenging ethical issues.
