[Serum sperm antibodies in women hospitalized for threatened abortion].

Abstract

The authors examined the antispermatozoal activity of 123 sera of patients hospitalized at the Gynaecological and Obstetric Department in Plzen during the 8th-9th week with diagnosis of imminent abortion. They revealed markedly higher antibodies against spermatozoa in particular in IgG, but also in IgA and IgM in 17 (13%) patients, who eventually had spontaneous abortions. The authors investigated also the obstetric history in connection with the presence of antibodies against spermatozoa. The antibody levels were higher in primary pregnant women.
