The prostatic utricle (Latin for "small pouch of the prostate") is a small indentation in the prostatic urethra, at the apex of the urethral crest, on the seminal colliculus (verumontanum), laterally flanked by openings of the ejaculatory ducts.
Seminal vesiculitis (also known as spermatocystitis) is an inflammation of the seminal vesicles, most often caused by bacterial infection. [15] Symptoms can include vague back or lower abdominal pain; pain of the penis, scrotum or peritoneum; painful ejaculation; blood in the semen on ejaculation; irritative and obstructive voiding symptoms ...

Attempts are sometimes made to diagnose an ejaculatory duct obstruction by means of medical imaging, e.g. transrectal ultrasound or MRI, [3] or by transrectal needle-aspiration of the seminal vesicles. However, transrectal ultrasound has a relatively low sensitivity of approx. 50% and thus is only a tool to rule-out cysts in the region of the ...
The presence of high levels of fructose (a sugar) is normal in the semen and originates almost entirely from the seminal vesicles. The seminal vesicles, which are major contributors to ejaculate volume, render semen viscous with a pH of 7.2–7.8. [1] An acidic seminal pH (pH < 7.2) suggests damage to the seminal vesicles and an alkaline ...
During emission, sperm flow from the cauda epididymis (which functions as a storage reservoir) into the vas deferens where they are propelled by the peristaltic action of muscle layers in the wall of the vas deferens, and are mixed with the diluting fluids of the prostate, seminal vesicles, and other accessory glands prior to ejaculation ...
The prostatic urethra, the widest and most dilatable part of the urethra canal, is about 3 cm long.. It runs almost vertically through the prostate from its base to its apex, lying nearer its anterior than its posterior surface; the form of the canal is spindle-shaped, being wider in the middle than at either extremity, and narrowest below, where it joins the membranous portion.
The exact cause of an epididymal cyst is unknown, but it is most likely a congenital anomaly associated with hormonal imbalances during embryonic life. [3] Previous research has shown a correlation between the development of epididymal cysts and maternal exposure to endocrine disrupting substances like diethylstilbestrol during male fetal development.
