Abstract
Summary: We developed a supravital stain of human sperm with fluorescent dyes. Either Hoechst 33 258 or fluorescein isothiocyanate could be used, the former stained sperm head while the later stained the whole sperm. Sperm vitality assessed with any of these two fluorescent dyes correlated well with that determined by eosin‐nigrosin counter‐stain. When sperm vitality was compared with sperm motility measured with a transmembrane migration method, we found that many vital sperm were immotile because sperm vitality was higher than sperm motility in tested samples. Zusammenfassung: Die Autoren entwickelten eine Supravitalfärbung mit Fluoreszenzfarbstoffen. Hierfür eigneten sich Hoechst 33 258 und ebenso Isothiocyanatfluorescein; Hoechst 33 258 färbte den Spermatozoenkopf, während Isothiocyanatfluoreszein das gesamte Spermatozoon anfärbte. Die Spermatozoenvitalität, die mit einem der beiden Farbstoffe bewertet wurde, korrelierte gut mit der Eosin‐Nigrosin‐Gegenfärbung. Wenn die Spermatozoenvitalität mit der Motilität verglichen wurde, die mittels einer Transmembran‐Migration‐Methode bestimmt wurde, so fand man, daß viele vitale Spermatozoen unbeweglich waren, weil die Spermatozoenvitalität höher war als die Spermatozoenmotilität in den untersuchten Spermaproben.Keywords
