Examination of the distribution of leucine aminopeptidase (LAP) activity in the male reproductive system showed the existence of the largest amounts of this enzyme in the prostate. Precipitin electrophoresis revealed that seminal LAP is immunologically identical with the prostatic enzyme and distinct from the enzymes in the other male reproductive organs. It was concluded that the origin of seminal LAP is the prostate, by which the enzyme is secreted into the seminal plasma.
对男性生殖系统中亮氨酸氨基肽酶（LAP）活性分布的检查显示，前列腺中这种酶的含量最高。沉淀素电泳显示，精液中的LAP与前列腺酶在免疫学上相同，与其他男性生殖器官中的酶不同。得出的结论是，精液中LAP的来源是前列腺，该酶由前列腺分泌到精浆中。
