The direct IgG-MAR test (mixed antiglobulin reaction test): results and correlations with seminal analysis in 1176 men from infertile couples.

The direct IgG mixed antiglobulin reaction (IgG-MAR) test was carried out as a screening test and as a routine test of semen analysis in 1176 male patients from infertile couples. We correlated the results of the IgG-MAR test with the semen analysis parameters. The test was only positive in 3.1% of the cases; other Authors describe incidences of much higher positive results than ours, for which reason we emphasize that our patients had not previously undergone any kind of preliminary section. The positive IgG-MAR test proved to correlate significantly both with the number and motility of the spermatozoa, while there appeared to be no correlation between its positiveness and the other parameters of the seminal liquid.
