title: Prevention of in vitro fertilization of canine oocytes by anti-ovary antisera: a potential approach to fertility control in the bitch.
abstract: Antisera raised against canine ovaries were found to induce light scattering of the surface of the egg zona pellucida even when diluted 10,000 times, and to delay digestion of the zona by pronase. High concentrations of antiserum were required, however, to inhibit in vitro fertilization of the oocytes. Absorption of the antisera with canine ovaries removed these effects, whereas absorption with liver, uterus and serum did not. These results demonstrate the antigenicity of the canine ovary and suggest the plausibility of an anti-zona pellucida vaccine for bith control in the bitch.
