Superoxide Dismutase Activity in the Oviductal and Uterine Fluid of the Bitch and the Effects of the Enzyme on Viability, Motility and Hyperactivation of Canine Sperm In Vitro

Superoxide dismutase (SOD) activity in flushings from oviducts and uterine horns of 8 anestrous, 5 estrous and 7 diestrous bitches was measured. SOD activity in oviductal fluid in estrous bitches was significantly higher than that in anestrous and diestrous bitches (P<0.01). SOD activity in uteri...

Sumario:Superoxide dismutase (SOD) activity in flushings from oviducts and uterine horns of 8 anestrous, 5 estrous and 7 diestrous bitches was measured. SOD activity in oviductal fluid in estrous bitches was significantly higher than that in anestrous and diestrous bitches (P<0.01). SOD activity in uterine fluid of diestrous bitches was, however, significantly higher than that in anestrous and estrous bitches (P<0.01). Additionally, sperm collected from normal dogs were incubated in MEM and in MEM containing SOD (SOD-MEM) for 24 hr. The percentages of sperm with viability, motility and hyperactivation in SOD-MEM were higher than those in MEM. SOD produced in oviduct and uterus may be able to maintain or improve sperm quality and fertility in the dog.
