Cervical secretion albumin, IgG, complement C3c, spinnbarkeit and amount of wet weight mucus recovered were analyzed in a group of 13 women using IUD as a contraceptive method and the results were compared to those obtained in a control group. Significant differences were obtained when concentrations and amounts of soluble proteins in the respective groups were compared, but spinnbarkeit and amount of wet weight mucus recovered were not affected by the presence of the IUDs.
