In experiment 1, semen was collected 10 times at intervals >of >48 hr, 24 hr and 12 hr in 4 of the 8 dogs, and the semen quality was >evaluated. In experiment 2, semen was collected 5 times at 24-hr intervals >in the other 4 dogs. The spermatozoa collected on day 1 and day 5 were >incubated for 4-6 hr in Canine Capacitation Medium, and the percentages of >hyperactivated sperm (%HA), acrosome-reacted sperm (%AR), and the zona >pellucida-binding sperm count (ZP sperm count) were assessed. The results >of >experiment 1 showed that the percentage of motile sperm increased and the >percentage of abnormal sperm decreased markedly as the intervals between >semen collections became shorter. When semen was collected at 12-hr >intervals, the percentage of motile sperm increased from about 65%, the >value before frequent collection was started, to about 80%, and the >percentage of sperm with abnormal tails decreased from 30% to 15%. In >experiment 2, the percentages of HA and AR, and the ZP sperm count in >specimens collected on day 5 were higher than those in specimens collected >on day 1, and the differences in % HA and in ZP sperm count were >significant >(P<0.05). The results demonstrated that sperm motility, abnormality, and >potential fertility in dogs with asthenozoospermia and teratozoospermia can >be temporarily improved by frequent semen collection. > >========================================================= >"Magic Commands": >to stop receiving mail for awhile, click here and send the email: >mailto:[EMAIL PROTECTED]?body=SET%20CKCS-L%20NOMAIL >to start it up gain click here: >mailto:[EMAIL PROTECTED]?body=SET%20CKCS-L%20MAIL > > E-mail [EMAIL PROTECTED] for assistance. >Search the Archives... http://apple.ease.lsoft.com/archives/ckcs-l.html > >All e-mail sent through CKCS-L is Copyright 2002 by its original author.
