[Spontaneous ascent of testes originally located in the scrotum]

The authors draws attention to possible postnatal changes the position of the testicle in the sensent of ascent. According to data in the literature and the author's own experience this ascent usually occurs as late as during school age. Causes of the altered position of the testicle are discussed. The condition is nowadays accepted but it is rare. From the practical aspects it is, however, necessary to examine the genitals of boys repeatedly and not only by a single examination. In case of a permanently inguinal position of the testicle the boy should be referred to a surgical department to prevent secondary damage of the testis by its incorrect position.
