The effect of a commercial deproteinized blood extract--on motility of human spermatozoa was examined in vitro. The improvement of motility as seen after addition of 5 and 10 percent of this deproteinized blood extract, is supposed to be due to amounts containing different concentrations of LH. The extract was ruled out as a source of kallikrein, but not as a source of kininogens.
在体外检测了一种商业用去蛋白血提取物对人类精子活力的影响。添加5%和10%的这种去蛋白血提取物后可见精子活力有所改善，推测这是由于提取物中含有不同浓度的促黄体生成素。该提取物被排除是激肽释放酶的来源，但不是激肽原的来源。
