Drosophila males transfer antibacterial proteins from their accessory gland and ejaculatory duct
to their mates.
Figure 1A-C was redrawn from figure la, d, and e in Bauer and Holt (1998), and modified by shading the testicular portion of the gonads and adding the androgenic glands, whose position along the ejaculatory duct
was observed in this study.
Vasography is not required and should be discouraged for men with an ejaculatory duct
obstruction (Level of Evidence 3, Grade C Recommendation).
Bulbous pars prostatica, 34-129 x 53-161, well developed with many prostate cells, surrounded by a thin membrane with a short ejaculatory duct
ending in a male genital papilla, located over the genital atrium.
The tip of the embolus with the ejaculatory duct
opening is inserted into the hole of the bursa copulatrix wall that leads into the copulatory duct (Fig.
3), (4) Symptomatic SVCs usually occur in the second to fourth decades of life, as the result of accumulated seminal fluid in the seminal vesicle caused by a blocked ejaculatory duct
3) Both may be secondary to testicular failure or obstruction inside the testis, epididymis, vas deferens or ejaculatory duct
One study, using P504S stain on prostate tissue, reported negative staining by P504S in the ejaculatory duct
or seminal vesicle epithelium.
The vas deferens consists of a tubule with various diameters that connects the posterior testicular region to the ejaculatory duct
in the posterior part of the abdomen.
The prostate narrows into a convoluted ejaculatory duct
that connects to the large, conical, unarmed penis (Fig 4).
Eisendrath and Ralnick describe the ejaculatory duct
at the outlet of the seminal vesicles as "a tortuous inelastic duct," refer to the "winding course" of the vas deferens as "quite tortuous," and discuss the "tortuosity" of its various compartments and foldings (56-57).
Hindbody with a linear series of accessory suckers on dorsal surface; atrial sucker also present in genital atrium; ejaculatory duct
fused with terminus of uterus; hermaphroditic canal thin-walled .
Structural abnormalities leading to hematospermia include prostatic, seminal vesicle and ejaculatory duct
cysts, ejaculatory duct
obstruction, and urethral stricture.
Zinner syndrome is a triad of mesonephric duct abnormality comprising of unilateral renal agenesis, ipsilateral seminal vesicle cyst, and ejaculatory duct
Cysts of seminal vesicle are associated with ipsilateral renal agenesis or dysplasia in two third of patients, presumably reflecting maldevelopment of distal mesonephric duct and faulty ureteral budding (leading to renal agenesis or dysplasia) and atresia of ejaculatory duct
(leading to obstruction and cystic dilatation of seminal vesicle (4.
