The addition of kallikrein to frozen semen after thawing increases the sperm motility in cases of moderate asthenozoospermia. In native semen maximal increase of motility is found two hours after the addition of kallikrein. In vivo an increase of sperm motility was noted in cases of oligozoospermia and asthenozoospermia during treatment with 600 KE kallikrein/day. The wives of 9 patients with asthenozoospermia became pregnant during kallikrein therapy.
解冻后向冷冻精液中添加激肽释放酶可提高中度弱精子症患者的精子活力。在天然精液中，添加激肽释放酶后两小时可发现活力达到最大增幅。在体内，用每日600激肽释放酶单位（KE）治疗少精子症和弱精子症患者时，可观察到精子活力增加。9名弱精子症患者的妻子在激肽释放酶治疗期间怀孕。
