For several years we have been looking at mammalian gametes and their interactions with the scanning electron microscope (SEM). Examining the images produced by the SEM has given us a three-dimensional view of sperm, eggs, and egg investments. We are particularly impressed with the structural variation among gametes of different mammalian species. In this short report we examine the structure of mammalian spermatozoa, eggs, zonae pellucidae, and cumuli. Our observations and those of others have led us to believe that variation in gamete structure and function may have evolved as a mechanism for reproductive isolation of mammalian species.
几年来，我们一直在用扫描电子显微镜（SEM）观察哺乳动物的配子及其相互作用。通过检查SEM产生的图像，我们对精子、卵子和卵膜有了三维视角。不同哺乳动物物种的配子在结构上的差异给我们留下了特别深刻的印象。在这份简短的报告中，我们研究了哺乳动物精子、卵子、透明带和卵丘的结构。我们以及其他人的观察结果使我们相信，配子结构和功能的差异可能是作为一种哺乳动物物种生殖隔离的机制而进化出来的。
