SummarySperm morphometric and morphologic data have been shown to represent useful tools for monitoring fertility, improving assisted reproduction techniques and conservation of genetic material as well as detecting inbreeding of endangered primates. We provide here for the first time sperm morphologic and morphometric data from Cercopithecus neglectus, Cercopithecus cephus, Papio papio and critically endangered Cercopithecus roloway, as well as comparative data from other Cercopithecinae species, i.e. Allochrocebus lhoesti, Mandrillus sphinx and Papio anubis. Following collection from the epididymis, spermatozoa were measured for each species for the following parameters: head length, head width, head perimeter, head area, midpiece length and total flagellum length, and the head volume, ellipticity, elongation, roughness and regularity were then calculated. Our data are consistent with both the general morphology and the morphometric proportions of Cercopithecinae sperm. Some specificities were observed, with C. cephus displaying a narrow head (width = 2.76 ± 0.26 µM) and C. roloway displaying a short midpiece (6.65 ± 0.61 µM). This data set represents an important contribution, especially for Cercopithecus roloway, one of the most endangered monkeys in the world, and further data on additional specimens coupled to data on mating systems and reproductive ecology should allow a better understanding of the mechanisms underlying these morphological differences across primate species.

尾猿精子的新见解

摘要精子形态测量和形态学数据已被证明是监测生育能力、改进辅助生殖技术和保护遗传物质以及检测濒临灭绝的灵长类动物近亲繁殖的有用工具。我们在这里首次提供来自长尾猴,头尾猴,狒狒狒狒并且极度濒危尾猴，以及其他的比较数据尾猿科物种，即长尾猴,狮身人面像和狒狒. 从附睾收集后，对每个物种的精子进行以下参数测量：头部长度、头部宽度、头部周长、头部面积、中段长度和总鞭毛长度，然后测量头部体积、椭圆度、伸长率、粗糙度和规则性计算出来的。我们的数据与一般形态学和形态学比例一致尾猿科精子。观察到一些特殊性，与C. cephus显示窄头（宽度 = 2.76 ± 0.26 µM）和C.罗洛威显示短中间件 (6.65 ± 0.61 µM)。这个数据集代表了一个重要的贡献，特别是对于尾猴，世界上最濒危的猴子之一，以及更多标本的进一步数据与交配系统和生殖生态学的数据相结合，应该可以更好地理解灵长类动物这些形态差异背后的机制。
