Toward standardization of the cut‐off value for the direct immunobead test using the postcoital test in immunologically infertile males

Abstract

A cut-off value of 20 % was correlated with the possibility of conception on treatment with IUI. The D-IBT is a screening test, and the value of 20 % initially suggested by Bronson et al. seems to be more appropriate than that of 50 % in the criteria defined by the World Health Organization.
