Seminal vesicles as organs of sperm storage.


:This study was done to determine whether or not the seminal vesicles store spermatozoa. Half of the nonhuman primates' vesicles had sperm at autopsy as did one of the men dying a traumatic death. Seminal vesicle sperm storage may be the reason for continued spermatozoa in the ejaculates of men after vasectomy. :These study results indicated that seminal vesicles sperm storage may explain the continued presence of spermatozoa in ejaculate of men after vasectomy. Examination of seminal vesicle sections of various subhuman primates revealed 11/24 specimens contained sperm. Species variation was evident in the primate results. Similarly, after regular electroejaculation all seminal vesicles of 4 sacrificed rhesus monkeys showed sperm present. 7 men, who died suddenly between the ages of 18 and 30, all had sperm in the ampullae. 1 subject had a moderate amount of sperm in the distal seminal vesicle. The remainder of the men showed no evidence of vesicular sperm. Though the frequency of vesicular sperm was lower in human than nonhuman subjects, it may nevertheless explain the occasional patient who continues to ejaculate sperm long after vasectomy and the occasional pregnancy which occurs in the absence of recanalization.
