title: The relation between sperm quality and the effect of ouabain on the motility of spermatozoa.
abstract: This paper reports the results of an investigation into the effect of ouabain on spermatozoa which have suffered from aging, sudden changes in temperature and deep-freezing. Normal spermatozoa of different boars under standard conditions show an evident variation in ouabain sensitivity. A definite relation could be established between the fertility of the semen of a boar and the ouabain sensitivity of this semen. Spermatozoa exposed to aging, sudden temperature changes or deep-freezing, showed a greater sensitivity for 10(-3)M ouabain than corresponding controls. We concluded that factors which are harmful to membrane quality of spermatozoa can be revealed by exposing them to ouabain.
