The vas deferens, also known as the ductus deferens or spermatic duct, is a tubular conduit that begins at the tail of the epididymis and ends by joining the excretory duct of the seminal vesicle to form the ejaculatory duct. The histology of the vas deferens in the fetus and neonate is not well studied, but some significant changes, especially in the structure of the muscular wall, are known to occur over the fetal period. This chapter reviews the development and histological changes in the vas deferens during gestation.
