[The non-scrotal testis].

In this article the classification of the nonscrotal testis is elucidated with a description of all forms of incomplete testicular descent. A great deal of attention is paid to the process of reaching the proper diagnosis, outlining the procedure for physical examination. The risk of infertility, the rather rare occurrence of testicular tumor, and a disturbance of the psychosexual development, are reasons why the undescended testis should be treated. How the undescended testis should be treated, hormonal or surgical, depends entirely on the position of the testis. LHRH nasal spray may induce descent in testes that have emerged from the inguinal canal and can be manipulated to at least the scrotal entrance. Surgical treatment is indicated for all undescended testes that have not emerged from the inguinal canal as well as all ectopic testes, and for those testes that failed to descend with hormonal therapy. The treatment protocol for all types of nonscrotal testes is discussed and schematically presented.
