Immunosuppression by seminal plasma and its possible biological significance

The data support the role of seminal plasma facilitating the transmission of virus and establishment of infection when all depositions of semen occur, but systemic absorption would also be possible by vaginal intercourse if lesions or abrasions caused for example by other s.t.d's, were present. The severity and rapid increase in the population of certain sexually transmitted agents make it imperative that epidemiological studies are initiated to study any correlation with changes in sexual behaviour and contraceptive practices. Finally, further isolation and characterization of seminal plasma components should lead to a clear understanding of their action as both regulatory molecules and in their possible contribution to disease.
