Pregnancy-associated plasma protein-A (PAPP-A) and phytohemagglutinin (PHA)-induced lymphocyte transformation were measured in split ejaculates of 17 normal volunteers. The concentration of PAPP-A was identical in both fractions of the ejaculate but the first fraction was twice as immunosuppressive as the second fraction. The origin of PAPP-A in men as well as its possibility of being an immunosuppressor is discussed.
在17名正常志愿者的分段射精样本中，检测了妊娠相关血浆蛋白A（PAPP-A）和植物血凝素（PHA）诱导的淋巴细胞转化情况。射精的两个部分中PAPP-A的浓度相同，但第一部分的免疫抑制作用是第二部分的两倍。文中讨论了男性体内PAPP-A的来源及其作为免疫抑制剂的可能性。
