Sperm Granuloma Histology
Sperm granuloma histology Aug 19, · Sperm granulomas are most commonly seen in the cauda epididymis but can occur throughout the epididymis, as well as the efferent ducts. If they occur in the efferent ducts and obstruct the outflow of sperm and fluid from the testis, they will result in secondary tubular dilation and/or atrophy in the associated testis due to the accumulated backpressure upstream.
Sperm granuloma is a granulomatous inflammatory reaction to extravasated spermatozoa following injury or inflammation of vas deferens or epididymis.

PATHOGENESIS: Spermatozoa develop after immune system development. Any defect, injury, infection, or degenerative change causing loss of epithelial and basement membrane integrity and exposes sperm antigens to the immune system can result in autoantibody formation with resultant sperm granulomas.
Sperm granulomas occur in at least 40 % of men following a vasectomy (Fig. ). Sperm granulomas are rarely symptomatic. However, 2–3 % of vasectomy patients will have pain attributed to sperm granulomas, usually occurring 2–3 weeks postoperatively.
