用孕酮处理过的兔子的子宫液中含有亚细胞膜。

Experientia. 1978 Mar 15;34(3):350-1. doi: 10.1007/BF01923028.

Uterine fluid from progesterone treated rabbits was shown to be rich in subcellular membrane components consisting of vesicles and cilia-like fragments. In contrast, uterine fluid from untreated does lacked subcellular membranes. Thus, they arise when uterine sperm capacitation ability is suppressed.

经孕酮处理的兔子的子宫液被证明富含由囊泡和纤毛样片段组成的亚细胞膜成分。相比之下，未经处理的母兔的子宫液缺乏亚细胞膜。因此，当子宫精子获能能力受到抑制时，它们就会出现。
