Correspondence: The spectrum of testicular-epididymal fusion anomalies in children with cryptorchidism: personal experience, systematic review and meta-analysis

Cryptorchidism occurs in 2-8% of boys, and cases who do not spontaneously resolve by age 1 require orchidopexy1. During orchidopexy it is common (15-40% in single center series) to encounter testicular-epididymal fusion abnormalities (TEFA), which may include isolated epididymal head or tail non-fusions (NF) as well as complete testicular-epididymal NF2. Despite the high prevalence of TEFA, the clinical significance of these variants has not been well-studied. Cryptorchidism, much like TEFA, presents on a spectrum (extent of descent) and the precise etiology is not well-characterized and likely involves hormonal and genetic factors3.
