| description | a granulomatous nodular lesion that appears in the region of epididymis and can be large enough to totally occlude the epididymal lumen; sperm granulomas are rounded or irregular in shape, and contain dense aggregates of immune cells and degenerating sperm resulting from an autoimmune response against sperm-associated antigens exposed following biochemical or surgical insult (e.g. vasectomy) to the epididymal epithelium |
