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.
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 ...
Pampiniform plexus [1] Lymphatic vessels [1] The tunica vaginalis is located in front of the spermatic cord, outside it. [3] Clinical significance.
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.
They unite and form a convoluted plexus, called the pampiniform plexus, which constitutes the greater mass of the spermatic cord; the vessels composing this plexus are very numerous, and ascend along the cord, in front of the ductus deferens.

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).
