The pampiniform plexus (from Latin pampinus 'tendril' and forma 'form') is a venous plexus – a network of many small veins found in the human male spermatic cord, and the suspensory ligament of the ovary. In the male, it is formed by the union of multiple testicular veins from the back of the testis and tributaries from the epididymis.
While one may expect the female to have an equal prevalence of pelvic compression syndrome due to the identical embryological origin of the valveless pampiniform plexus, this condition is thought to be underdiagnosed due to the broad differential of the pain pattern: unilateral or bilateral pain, dull to sharp, constant to intermittent pain worsening with any increase in abdominal pressure.
A varicocele is, in a man, an abnormal enlargement of the pampiniform venous plexus in the scrotum; in a woman, it is an abnormal painful swelling to the embryologically identical pampiniform venous plexus; it is more commonly called pelvic compression syndrome. In the male varicocele, this plexus of veins drains blood from the testicles back ...
Valveless testicular veins are a major contributing factor to varicocele. [1] Since the left testicular vein goes all the way up to the left renal vein before it empties, this results in a higher tendency for the left testicle to develop varicocele because of the gravity working on the column of blood in this vein, compared to the right internal spermatic vein.
The spermatic cord is the cord-like structure in males formed by the vas deferens (ductus deferens) and surrounding tissue that runs from the deep inguinal ring down to each testicle.
The bulb of penis is the proximal/posterior bulged [1] end of the (unpaired median) corpus spongiosum penis.Together with the two crura (one crus on each side of the bulb), it constitutes the root of the penis. [2]
They differ in size according to their position, those in the middle of the gland being larger and longer. The lobules are conical in shape, the base being directed toward the circumference of the organ, the apex toward the mediastinum testis.
The spermatic plexus (or testicular plexus) is derived from the renal plexus, receiving branches from the aortic plexus. It accompanies the internal spermatic artery to the testis . Additional images
