Pampiniform venous plexus: The pampiniform plexus is a network of many small veins found in the human male spermatic cord. It is formed by the union of multiple spermatic veins from the back of the testis and tributaries from the epididymis.Testicular torsionKlatskin tumorVasovasostomyHydrocele: A hydrocele (Br English: hydrocoele) denotes a pathological accumulation of serous fluid in a body cavity.VaricoceleSolid pseudopapillary tumour: A solid pseudopapillary tumour (also known as solid pseudopapillary neoplasm or, more formally, solid pseudopapillary tumour/neoplasm of the pancreas) is a low-grade malignant neoplasm of the pancreas of papillary architecture that typically afflicts young women.Orchialgia: Orchialgia is long-term pain of the testes. It is considered chronic if it has persisted for more than 3 months.Neuromere: Neuromeres are morphologically or molecularly defined transient segments of the early developing brain. Rhombomeres are such segments that make up the rhombencephalon or hindbrain.Circulatory anastomosis: A circulatory anastomosis is a connection (an anastomosis) between two blood vessels, such as between arteries (arterio-arterial anastomosis), between veins (veno-venous anastomosis) or between an artery and a vein (arterio-venous anastomosis). Anastomoses between arteries and between veins result in a multitude of arteries and veins, respectively, serving the same volume of tissue.LiposarcomaBlood–testis barrier: The blood–testis barrier is a physical barrier between the blood vessels and the seminiferous tubules of the animal testes. The name "blood-testis barrier" is misleading in that it is not a blood-organ barrier in a strict sense, but is formed between Sertoli cells of the seminiferous tubule and as such isolates the further developed stages of germ cells from the blood.EpididymitisInguinal hernia surgery: Inguinal hernia surgery refers to a surgical operation for the correction of an inguinal hernia. Surgery is not generally advised in most cases if the Hernia produces no symptoms; watchful waiting being the recommended option.Biliary tract: The biliary tract, (biliary tree or biliary system) refers to the liver, gall bladder and bile ducts, and how they work together to make, store and secrete bile. Bile consists of water, electrolytes, bile acids, cholesterol, phospholipids and conjugated bilirubin.Bob Champion
