用含有0.005 M CaCl 2的Triton X-100溶液提取的精子，在含有低浓度（10 - 9 M）游离钙离子的ATP溶液中重新激活时，具有几乎对称的鞭毛搏动模式和直线游泳路径。再活化溶液中钙的增加，或提取溶液中钙的缺失，会导致鞭毛的不对称跳动和圆形游泳路径。
Spermatozoa extracted with Triton X-100 solutions containing 0.005 M CaCl2have nearly symmetrical flagellar beat patterns and straight swimming paths when reactivated in ATP solutions containing low concentrations (10−9M) of free calcium ion. Increased calcium in the reactivation solutions, or omission of calcium from the extraction solution, causes asymmetrical flagellar beating, and circular swimming paths.
