摘要: 本文对刚接近性成熟大熊猫的精液在电子显微镜下进行精液品质鉴定,观察结果,除少量完成变态的精于外,多数是处在精子发生的各阶段并发育不正常,精液中伴随着大量巨噬细胞和被吞噬的衰亡精子及其碎片。镜检结果不仅说明这只雄性太熊猫性尚未成熟,其生殖系统可能还伴有生理或病理现象,这样的精液建议不能用于配种。

Abstract: In this study,morphology of sperm and non-sperm cells in semen of giant panda were investigated by transmission electron microscopy.It was showed that certain number of exfoliated spermatids.spermatocytes,malformed spermatozoa as well as macrophages with one or two nucleus and debris of degenerated spermatids were seen in the semen.The results suggested that the gonad of the male giant panda examined is of a non-mature and it may also be accompanied by some phenomena of physiologica1.and pathological abnormal .So the semen like this kind can not be used for insemination.
