Objective The aim of the present study was to assess, the sonographic rate of detection of undescended testes among a low‐risk population during the third trimester. Study methods 332 women between 34 and 40 weeks of pregnancy underwent prospectively an ultrasonographic evaluation including biometrical studies and detailed study of the fetal genitals. The presence of the testes within the scrotum was examined by a qualified neonatologist within 3 days after birth. Results Of the 332 fetuses that were examined, the scrotum was visible in 294 of them (89%). Nine cases of undescended testes were detected (3%). Of these, the diagnosis of one case, examined at 34 weeks of gestation, was a false positive one as revealed after birth. There was no false negative result. The present series has delineated the best timing for the detection during the late 3rd trimester as being between 34 and 36 weeks of pregnancy. When undescended testes is diagnosed, a second evaluation is recommended at around 37 weeks of pregnancy. Discussion Ultrasound examination during the late third trimester of pregnancy appears to allow an accurate diagnosis of undescended testes prenatally. This early identification will alert the neonatologist of the possibility of cryptorchidism and permit early postnatal identification and treatment.
