Spermatozoal SOD activity was positively correlated to sperm motility, normal morphology and sperm swelling by sperm hypo-osmotic...

提示精子SOD活性与精子结构、功能有关，可作为衡量精液质量的一个新指标。

To observe the spermic activity by using the microscope after mix ing fresh sperm with anti-sperm antibody,we daubed the hamster s vagina with anti-sperm antibody Gel once a day for 14 days,and then anatomised hamsters,obtain effective the vaginal tissue and observed the pathologic slices.

将抗精子抗体与新鲜精液直接混合后镜检；用导管将抗精子抗体凝胶涂布于地鼠阴道内，每天一次，两周后解剖做病理切片观察并评分。

A unique example of sperm cooperation in monotremes is used as evidence that the epididymis produces sperm competition proteins to form groups of 100 sperm into bundles that have a forward motility nearly thrice that of individual spermatozoa.
