Genital Ducts

• I\ibuli recti—connect the seminiferous tubules with the rete testis. Continuous production of testicular fluid by Sertoli cells helps to move the gametes out of the seminiferous tubules.

• Rete testis—consists of an anastomosing labyrinth of channels with in the mediastinum that converge toward the efferent ductules

■ Efferent ductules—lined by a pseudostratified, ciliated epithelium

• Ductus epididymis—a single, elongated tortuous duct that may be 6 m or more in length

It is lined by a pseudostratified epithelium containing stereocilia.

It is here that sperm undergo maturation and develop increased motility and fertilizing capacity.

• Ductus deferens (vas deferens)—contains a thick muscular coat, which dilates distally into an ampulla. The ampulla gradually narrows to form the ejaculatory duct, which penetrates the prostate gland and empties into the urethra.
