The testicular portion is equipped with vasa deferentia and ejaculatory ducts
opening to the exterior by gonopores on the coxae of the fifth pereopods (i.
5 the length of gonocoxite, without subterminal fine seta and four spiniform setae present; paramere simple, apex rounded and without isolated setae near the middle on dorsal margin; ejaculatory ducts
simple; lateral lobe thin.
Obstruction of the ejaculatory duct
is usually detected by a TRUS and is usually accompanied by dilation of the seminal vesicles (typically >1.
The vas deferens, ejaculatory duct
and lower two-thirds of the epididymis also arise from mesonephric duct system.
Low volume is associated with ejaculatory duct
obstruction, congenital bilateral absence of the vas deferens (CBAVD), retrograde ejaculation or androgen deficiency.
8) However, there have been no studies using P504S/p63 in a single-color cocktail to distinguish prostatic cancer involvement in seminal vesicles versus cancer mimickers because of the architectural complexity of the seminal vesicles and ejaculatory ducts
Males may alter the velocity of sperm they allocate to copulations by strategically firing their left and right ejaculatory ducts
, which can operate independently," they say.
rubripes is bilaterally symmetrical, located in the anterolateral portion of the cephalothorax and consists of testes connected by a testicular commissure (Figure 11), vas deferens and ejaculatory ducts
Cysts in the Mullerian duct can, as a result of the duct's extrinsic compression, also lead to blockage of the ejaculatory ducts
, although again this does not seem to produce symptoms today that exactly match Sade's (189ff).
In order for ejaculation to occur, sperm must be transported from where it is made in each testicle to the neighbouring epididymii, along the long vas deferens, into the seminal vesicles, ejaculatory ducts
and into the prostatic urethra (a neurological event called the emission phase of the ejaculation reflex).
In addition, a recent study of the Medicare population indicated that the rate of radical prostatectomies (the removal of the prostate gland, ejaculatory ducts
, and seminal vesicles) increased nearly sixfold from 1984 through 1990 .
1) Utricle is derived from the Latin word "pouch, " which forms a cul-de-sac 6 mm long, located in the verumontanum between the two ejaculatory ducts
that projects upward and backward into the substance of the prostate.
Since the cysts were close to the pelvic nerves, ureters, rectum, ejaculatory ducts
and vas deferens, surgery was a challenge.
An effective treatment method for the pathologies that impair the peristaltism and lead to atonic obstruction in the male reproductive ejection ducts which eventually cause partial and functional obstruction of the ejaculatory ducts
has not been defined yet.
1,2] It may involve prostatic ducts, ejaculatory ducts
, utricle, or adjacent urethral mucosa.
