Abstract
Pregnancy-associated plasma protein-A (PAPP-A) and inhibition of phytohemagglutinin (PHA)-induced lymphocyte transformation were measured in 51 seminal plasma samples obtained from oligozoospermic (n = 22), normospermic (n = 22), and vasectomized men (n = 7). In nonvasectomized men, PAPP-A significantly correlated with the percentage inhibition of lymphocyte transformation. The possibility of PAPP-A being an immunosuppressive principle of human seminal plasma is discussed.Keywords
