Post-vasectomy pain syndrome is a chronic and sometimes debilitating genital pain condition that may develop immediately or several years after vasectomy.
There is a noticeable increase in pressure within the vas deferens on the testicular side following vasectomy.[SUP][8][/SUP] The epididymides of vasectomized men are often swollen and distended from backpressure effects.[SUP][8][/SUP] The efferent ducts and seminiferous tubules of the testes are also impacted by backpressure, leading to an increase in area and thickness.[SUP][9][/SUP] Backpressure from blockage of the vas deferens causes a rupture in the epididymis, called an "epididymal blowout", in over half of vasectomy patients.[SUP][3][/SUP] Sperm sometimes leak from the vas deferens of vasectomized men, forming lesions in the scrotum known as sperm granulomas. Some sperm granulomas can be painful.[SUP][10][/SUP] Paradoxically, the presence of a sperm granuloma at the vasectomy site prevents epididymal pressure build-up, perforation, and the formation of an epididymal sperm granuloma. It thus lessens the likelihood of epididymal discomfort.[SUP][11][/SUP]
