The survival test is positive if this difference is inferior to 20% (Table 3). The impression is that B2 medium favours deficient sperms - however, no significant difference is found between the two methods. Fertilization rates in the two methods The study of the fertilization rate also shows no significant difference between the two methods (Table 4). B2 Menezo medium does not improve the fertiliza. tion rate, but is equally good for a fertilization check. Table 4 Fertilization rate in BWW versus B2 medium Fertilized eggs Unfertilized eggs 93 92 636 572 not significant by x 2-test Variation of the contact-time for one sperm An experimental donor with a very good proven fertility was tested several times.
The Menezo B2 method is, nevertheless, a very simple one and represents a good test for human IVF. S). There is no obvious correlation between motility, clinical fertility and fertilization rates, the interpretation of the test is still disturbed by borderline pictures. In the full meaning of a diagnostic test this is not a reproducible method. In conclusion, this test cannot be used as a selecting test for IVF or artificial insemination donors, but it shows a good degree of repetition for sperm resistance before a human IVF.
