[Sperm granulomata].

Sperm granulomata are rare without prior surgical intervention but constitute a common complication of vasectomy and affect 35 and 42% with the conventional methods. Refertilizing and sperm quality are better in cases of sperm granulomata and, as opposed to previous assumptions, reduced fertility is not found in cases of sperm granulomata in patients with sperm antibodies. Fewer complaints are observed after open end vasectomy despite the particularly high incidence of sperm granulomata. Unfortunately, the literature does not appear to contain randomized investigations as guidelines for the choice of surgical method for vasectomy.
