研究了伴随获能的精子游动模式的变化。观察到精子在获能后开始激活运动。在低温、无Ca2+、添加Zn2+和添加Fr的情况下，精子活化均受到抑制。 I来自豚鼠精子，其对兔精子具有断能活性。然而，在相同条件下，当精子已经获得激活的运动时，运动并没有受到抑制。显然，只有当获能过程受到抑制时，精子的活化才会受到抑制。因此，表明精子激活是精子获能的固有特性。
The changes of swimming patterns of spermatozoa accompanying capacitation were studied. The spermatozoa were seen to begin activated movement upon capacitation. The sperm activation was inhibited at low temperatures, in the absence of Ca2+, upon addition of Zn2+, and upon addition of Fr. I from guinea-pig spermatozoa which had decapacitation activity against rabbit spermatozoa. However, movement was not inhibited under the same conditions, when the spermatozoa had already acquired activated movement. It was apparent that the activation of spermatozoa was inhibited only when the prccess of capacitation was suppressed. Thus it is suggested that sperm activation is an inherent property of sperm capacitation.
