Egg yolk coating fails to preserve bovine sperm quality after freezing.
Sperm coating with Triladyl® during ejaculation does not improve the quality of frozen-thawed bovine sperm. The study compared sperm collected in a tube with egg yolk-Tris extender to sperm collected in a regular tube. After freezing and thawing, there were no significant differences in sperm motility or membrane integrity between the two groups. The method of sperm collection did not affect the quality of the sperm after cryopreservation.
