用高速电影显微摄影技术研究了仓鼠和豚鼠精子与透明质酸结合前后的运动特性。先前在体内或体外经历过运动激活的精子在贴壁后保持活跃的行为。他们继续传播鞭毛波的大幅度和曲率,虽然这些波是更对称的比之前的鞭毛附件。体外激活的仓鼠精子在贴壁时出现轻微刺激。这些精子也与小鼠卵的透明带结合,它们表现出类似的运动。预激活的仓鼠精子,新鲜的附睾,并附着到仓鼠睾丸,但表现出相对较弱的鞭毛拍低的振幅和频率。豚鼠精子,在体外激活,也继续这样的运动,似乎有点刺激后,附件的透明细胞的物种。
Movement characteristics of hamster and guinea pig spermatozoa were studied by high-speed cinemicrography before and after initial binding to the zona pellucida. Hamster spermatozoa that had previously undergone motility activation in vivo or in vitro maintained vigorous behavior upon zona attachment. They continued to propagate flagellar waves of large amplitude and curvature, although these waves were much more symmetrical than when prior to zona attachment. The hamster sperm activated in vitro appeared slightly stimulated upon zona attachment. Such spermatozoa also bound to the zonae pellucidae of mouse eggs, and they exhibited similar movements. Preactivated hamster spermatozoa, fresh from the epididymis, did attach to the hamster zona, but exhibited relatively weak flagellar beats of low amplitude and frequency. Guinea pig spermatozoa, activated in vitro, also continued such movement and appeared somewhat stimulated upon attachment to the zona pellucida of their species.
