Controlled trial of treatment of recurrent spontaneous abortion by immunisation with paternal cells.

Abstract In a paired sequential double-blind trial of immunological treatment of recurrent spontaneous abortion successful outcome of the next pregnancy was significantly more common in women injected with purified lymphocytes prepared from their husbands' blood than in those injected with their own lymphocytes. 17 of 22 women given paternal cells had successful pregnancies, compared with 10 of 27 given their own cells.
