Immunoglobulin levels in seminal plasma of oligospermic patients

The levels of immunoglobulins in the seminal plasma of healthy males were compared with those of oligospermic patients. The results show markedly increased levels of IgG in oligospermic patients. The presence of IgM, which has not been detected in the seminal plasma of healthy males, was estimated in some of the oligospermic patients. The authors recommend this simple screening test to be carried out in every male infertility follow up.
