The ductus deferens is identified (Fig la) and carefully debrided as it emerges from the epididymis.
The use of a fine blunt probe aids in debriding and differentiating the ductus deferens within the subcutaneous space (Fig 2b).
During sexual stimulation, smooth muscle cells in the tail contract and push the epididymal contents into the ductus deferens. A second mechanism involves periodic contractions of the epididymal tail and ductus deferens, causing more sustained release.
The ductus deferens is coiled where it emerges from the epididymis.
Unlike the epididymis and efferent ducts, the ductus deferens has a well-defined tunica serosa.
Prostate gland One of the accessory sex glands located at the origin of the urethra at the site where the two ductus deferens converge.
Vesicular glands A pair of male accessory sex glands situated laterally to the ductus deferens and dorsal to the pelvic urethra.
Wolffian ducts The embryonic ducts that develop into the epididymis and ductus deferens. Also called the mesonephric ducts.
The extratesticular seminiferous path is made up bilaterally of the epididymis and ductus deferens. The epididymis are firmly applied to the corresponding testis dorsomedial face and continue with the ductus deferens, which are located at the sides of the body median line medially to the ureters (Fig.
Several works agree with our results as for the epididymis size and position and the ductus deferens site and tortuousity (Kaupp; Lake, 1957; Amer & Shahin; Tingari, Mercadante et al.
The ductus deferens descending course parallel to the ureter in direction to the urodeo is similar in fowl (Lake, 1957; King), male pigeon (Mercadante et al.), and it was confirmed in this study.
