title: The retractile testis.
abstract: One hundred boys who had a retractile testis on one side were followed up for five years. The position of the retractile testis became higher (in some, it left the scrotum) in 42 boys and the development of this testis was adversely affected in 49. Because of this, regular review of boys with retractile testes should be continued as long as retraction persists.
