Qin KR, et al. - Via conducting a retrospective review (2010-2018) of all people undergone orchidopexy, experts intend to clarify the real incidence of testicular-epididymal fusion anomalies (TEFA) in infants with undescended testes and their effect on testicular development following surgery. At the time of surgery, cases with TEFA confirmed intra-operatively were matched against controls with normal fusion for age. They found 54 out of 252 cryptorchid testes to had TEFA in a retrospective review. In comparison with inguinal testes, intra-abdominal testes were more likely to show TEFA. Data was found from retrospective review and the literature show that TEFA were present in nearly one-quarter of cryptorchid testes and were more commonly correlated with intra-abdominal cryptorchidism. Moreover, at short-term follow-up, their appearance gives no effect on testicular size. It was noted that the clinical significance of TEFA was not clear and for better understanding, the effect on testicular development and function, long-term follow-up studies were important.
