Current therapy for undescended testicle. Rationale for treatment between ages four and five

Clinical experience suggests that the undescended testis is best maintained in a scrotal position. This provides the best opportunity for realization of any remaining fertility potential and facilitates easier examination for neoplastic evidence with heretofore neglected important psychological considerations, and leads to the conclusion that therapy is best carried out between the 4th and 5th birthdays. The potential psychological impact of the migratory testis similarly warrants gonadotropin therapy between the ages of 4 and 5 yr.
