Abstract
Summary Spermatozoa from 269 male partners of infertile couples were assessed using both the mixed erythrocyte-spermatozoa antiglobulin reaction (MAR test) against IgG and the heterologous ovum penetration test. Penetration of zona-free hamster ova occurred with spermatozoa from 39 out of 60 men (65 per cent) with a positive MAR (IgG) test result, and statistical analysis demonstrated that the penetration of zona-free hamster ova is not related to the result of the MAR (IgG) test.
