Leucine aminopeptidase (LAP) enzymatic activity has been measured in the seminal fluid of a group of 119 males undergoing fertility check-up, and correlated with spermatic density. The results indicate that there exists a direct correlation between LAP activity in the seminal plasma and spermatic density. However, differences between the groups considered according to spermatic density are not significant. Seminal plasma mean leucine aminopeptidase is 40 times higher than that found in blood plasma.
已对119名接受生育检查的男性精液中的亮氨酸氨肽酶（LAP）酶活性进行了测量，并将其与精子密度相关联。结果表明，精浆中的LAP活性与精子密度之间存在直接相关性。然而，根据精子密度划分的各研究组之间的差异并不显著。精浆中亮氨酸氨肽酶的平均含量比血浆中的含量高40倍。
