Abstract
The immunobead test (IBT) was applied to bromelin-treated cervical mucus (CM) samples from 78 infertile women. Seven (8.9%) of the patients were positive for IgG and/or IgA class antibodies, while none (0/35) were found positive for IgM class antibodies. Of the positive samples 57% contained IgG and IgA classes, while the remaining samples contained IgA alone. The implications of these results were discussed.
