| Abstract |
|
Early studies demonstrated that seminal plasma has a factor which inhibits fertilizing ability in a reversible manner. The factor can be precipitated by centrifugation at 104000g for 18 hr. The precipitate was applied to a CM cellulose column and eluted with high salt concentration. This fraction possessed antifertilizing activity was applied to a Sephacryl S-200 column according to a modification of the method of Reddy et al. Using such inhibition of in vitro fertilization ability as an assay, we have carried our experiments to purified the factor. When the factor was added to IVF medium, 70-80% of fertilization was inhibited. |
