15 صفحه اولThe need for epididymovasostomy at vasectomy reversal plateaus in older vasectomies: a study of 1229 cases
Vasectomy reversal involves either vasovasostomy (VV) or epididymovasostomy (EV), and rates of epididymal obstruction and EV increase with time after vasectomy. However, as older vasectomies may not require EV for successful reversal, we hypothesized that sperm production falls after vasectomy and can protect the system from epididymal blowout. Our objective was to define how the need for EV at...
متن کاملMorphometric study of the testis and reproductive tract (including sperm granuloma) after vasectomy in mature rats
By utilizing the rabbit model, previous studies have found good evidence indicating that vasectomy-induced spermatogenic damage is pressure-mediated: the damage occurs when the occluded reproductive tract is unable to accommodate additional spermatozoa produced by the testis. More studies with the more commonly used rat model have shown, however, controversial results on whether and why the dam...
متن کاملAdverse effects of vasectomy: sperm granuloma of epididymides.

Epididymal weights were increased in all groups of vasectomized animals, whereas testicular weights did not change. Granuloma in the form of yellow nodular masses of cysts were present at the lower pole of the epididymis. It consisted of a pool of sperm and o...
