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 ...
The head (Latin: caput). The head of the epididymis receives spermatozoa via the efferent ducts of the mediastinium of the testis [3] at the superior pole of the testis. [2]: 1296 The head is characterized histologically by a thick epithelium with long stereocilia (described below) and a little smooth muscle. [3]
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 seminal pH (pH > 8) suggests prostatic involvement. [2] In addition, low fructose may indicate problems in the prostate, while low semen ...
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 tunica albuginea is a dense, [1] [2] blue-white [3] layer of fibrous tissue surrounding the testis. [1] [4] It is the middle of three envelopes forming the capsule of the testis; it is deep to the visceral layer of tunica vaginalis, and superficial to the tunica vasculosa testis (vascular layer of testis).
Together with the secretions from the seminal vesicles, these form the major fluid part of semen. [4] The prostate contains various metals, including zinc, [20] and is known to be the primary source of most metals found in semen, which are released during ejaculation. [21]
Such spread typically results in Troisier's sign, which is the finding of an enlarged, hard Virchow's node. [1] The left supraclavicular nodes are the classical Virchow's node because they receive lymphatic drainage of most of the body (from the thoracic duct) and enters the venous circulation via the left subclavian vein. The metastasis may ...
