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.
The rete testis (/ ˈ r iː t i ˈ t ɛ s t ɪ s / REE-tee TES-tis; pl.: retia testes) is an anastomosing network of delicate tubules located in the hilum of the testicle (mediastinum testis) that carries sperm from the seminiferous tubules to the efferent ducts.
In birds with webbed feet, retia mirabilia in the legs and feet transfer heat from the outgoing (hot) blood in the arteries to the incoming (cold) blood in the veins.The effect of this biological heat exchanger is that the internal temperature of the feet is much closer to the ambient temperature, thus reducing heat loss.
The testicles are very sensitive to impact and injury. The pain involved travels up from each testicle into the abdominal cavity, via the spermatic plexus, which is the primary nerve of each testicle. [31] This will cause pain in the hip and the back. The pain usually fades within a few minutes. Testicular torsion is a medical emergency. This ...

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 ...

The septum of scrotum or scrotal septum [1] is an incomplete vertical wall that divides the scrotum into two compartments –each containing a single testis.It consists of flexible connective tissue and nonstriated muscle (dartos fascia). [2]
