Infertile patients with positive immunofluorescent serum spermatozoal antibodies treated by condom coitus.

13 infertile women were selected on the basis of having abnormal postcoital and invasion tests and serum spermatozoal antibodies. Immunofluorescent sperm antibody tests were carried out by indirect method (Wall et al.). Cervical hostility was demonstrated using the sperm penetration slide test of Miller and Krusrock. Sheath coitus was instituted and further antibody tests were carried out at 2-month intervals for 6 months; 1 year after treatment the blood was tested for spermatozoal antibodies. Antibody titers fell in 12 of the patients 3 pregnancies ensued and the invasion test improved in 7. 1 year after treatment significant titers were again detected in 8 of the 10 patients who were retested.
