The invention relates to improvements in determining the fertilizing capacity of a human semen sample using a reagent solution which contains 0.1-5% by weight K2PO4H/KPO4H2 to adjust the pH of the solution to 6.5-8.0. After treatment with the reagent solution, the result is considered positive when the diameter of the halo is equal to or larger than 7.5 mu in 10-25% of the spermatozoa read, as long as the membrane of the head of the spermatozoon is intact. Kits suitable for performance of the claimed method are also described.
