[Testis biopsy and measurement of its volume in cryptorchidism (author's transl)]

The recommendation of an optimal time for operation of cryptorchidism is based on 70 testis biopsies and 40 measurements of testis volume. Orchidopexy should be performed during the 3rd to the 4th year of age, because impairment of the testes is not to be expected until the beginning of the 3rd year of life. Orchidopexy within the first two years of life may cause additional traumatization of the tissue.
