Viable spermatozoa in the bladder after electroejaculation of lion-tailed macaques (Macaca silenus)

The bladder of 6 lion-tailed macaques was emptied and flushed with sterile saline. TALP-Hepes buffer was infused and the animals were electroejaculated. After electroejaculation, the semen quality was determined in the ejaculate and the bladder infusate. Of the 15 ejaculates analysed, a mean (+/- s.e.m.) sperm count of 133.8 (+/- 30.7) x 10(6) with 69.5 (+/- 6.0)% motility was obtained in the infusate as compared to the sperm count of 72.4 (+/- 38.6) x 10(6) with significantly lower (47.7 +/- 5.8%) motility in the ejaculate.
