Résumé

L'observation directe de la surface du sperme et de l'œuf au microscope électronique «scanning» a montré une série de changements dans le spermatozoïde du Hamster doré avant la fertilisation ainsi que la relation topographique entre le spermatosoïde et l'œuf au moment de la fertilisation. Il semble que les microvilli de l'œuf participent activement à l'incorporation de la tête du sperme dans le cytoplasme de l'œuf.
