Spontaneous and ionophore-induced ability of spermatozoa to acrosome-react was examined in asthenozoospermic infertile patients and fertile donors. Spermatozoa were washed free of seminal plasma and capacitated in B2 medium for 2 h at 37°C. Subsequently 5, 10, 20 and 30 μM A23187 (final concentrations) were added to equal aliquots of these samples and incubated for an additional 30 min. The acrosome reaction was then determined by the triple stain technique. The percentage of spontaneous reaction (no ionophore) in asthenozoospermic samples was similar to that in fertile samples (4.2 and 3.8, respectively). However, the ionophore-induced reaction rate remained significantly lower in asthenozoospermic samples than in normozoospermic samples. [ABSTRACT FROM PUBLISHER] |
