Reproductive immunology: 1. The effect of different protein concentrations of seminal plasma on in vitro lymphocyte cultures.

Certain components of the male genital tract are capable of inhibiting the transformation rates of in vitro lymphocyte cultures. In the present study the effect of human seminal plasma was investigated for it inhibitory properties when used in varying protein concentrations together with different dilutions of Phytohaemagglutin-M (PHA-M). It is concluded that whole human seminal plasma is suitable in inhibition studies provided an optimal protein concentration is used.
