Low volume is associated with ejaculatory duct
obstruction, congenital bilateral absence of the vas deferens (CBAVD), retrograde ejaculation or androgen deficiency.
One study, using P504S stain on prostate tissue, reported negative staining by P504S in the ejaculatory duct
or seminal vesicle epithelium.
Hindbody without accessory and atrial suckers; ejaculatory duct
united with side of paraprostate organ; hermaphroditic canal has thick muscular wall .
Treatment usually includes seminal way disclosure via transurethral resection of the ejaculatory duct
and open, laparoscopic or robotic vesiculectomy.
Histologic Mimickers of Prostatic Adenocarcinoma Small gland pattern Lesions of prostatic epithelial origin Atrophy Adenosis (atypical adenomatous hyperplasia) Crowded benign glands Sclerosing adenosis Basal cell hyperplasia Radiation and reactive atypia Verumontanum mucosal gland hyperplasia Lesions of nonprostatic epithelial origin Seminal vesicle and ejaculatory duct

The mesonephric duct differentiates into the appendix of the epididymis, paradidymis, vas deferens, ejaculatory duct
, seminal vesicles and hemitrigone.
The ejaculatory duct
occupies the length of the embolus and opens at its tip.
Since the cysts were close to the pelvic nerves, ureters, rectum, ejaculatory ducts
and vas deferens, surgery was a challenge.
Pryor JP, Hendry WE Ejaculatory duct
obstruction in subfertile males: analysis of 87 patients.
1,2] It may involve prostatic ducts, ejaculatory ducts
, utricle, or adjacent urethral mucosa.
4] In both cases, the neurovascular bundle, the distal sphinteric complex, and the continuity of the vas, seminal vesicles and ejaculatory duct
The whole lesion was excised at the level of the ipsilateral ejaculatory duct
The internal sphincter (bladder neck) is proximal to the ejaculatory duct
orifice, and contracts during emission and ejaculation to prevent retrograde ejaculation.
Obstruction of the ejaculatory duct
is usually detected by a TRUS and is usually accompanied by dilation of the seminal vesicles (typically >1.
8 cm was identified in the right midland/base (Figure 1), abutting the central zone right of midline, coursing along and invading the right ejaculatory duct
