Every structure in the body requires blood flow - inflow of fresh blood through arteries and outflow of blood through veins. The testes are no different - in fact, there are 5 recognized venous drainage systems from the testicles:. The venous drainage system acts as a 'heat exchange system' which keeps the operating temperature of the testis below that of core body temperature. Sperm production works best when the temperature is a little lower. The blood returning in veins leaving the testis cools the incoming blood entering the testis from the arteries. This arterio-venous heat exchange system is called the the pampiniform plexus.
Recovery of spermatogenesis after microsurgical subinguinal varicocele repair in azoospermic men based on testicular histology. Sandro C. Esteves; Sidney Glina. Correspondence address. OBJECTIVE: Analyze whether testicular histologic patterns from a group of azoospermic men with varicocele is predictive of treatment outcome after subinguinal microsurgical varicocele repair. The mean time for appearance of spermatozoa in the ejaculates was 5 months 3 to 9 months.
