Post-ejaculation of sperms into the female reproductive tract, acquisition of sperm capacitation is an essential step in the fertilization process. Accordingly, during in-vitro fertilization, the successful fertilization requires necessarily induction of capacitation in the retrieved sperms. To date, many candidate substances have been considered as capacitation inducers. However, there were no reports about the comparison of efficiency inducing sperm capacitation among diverse capacitation inducers. Therefore, we tried to determine an inducer showing the best capacitation performance in mouse sperms by comparing the preimplantation development of in-vitro-fertilized embryos using sperms experiencing capacitation by a variety of capacitation inducers. For these, calcium, progesterone, bovine serum albumin (BSA), heparin, lysophosphaticylcholine (Lyso-PC) were used as candidate capacitation inducers. Optimized concentration of each inducer were determined by accessing ratio of sperms experiencing acrosome reaction using coomassie G-250 blue staining. Subsequently, in vitro fertilization was performed using sperms incubated in each optimized concentration inducer. The ratio of fertilized oocytes was observed. As the results, Calcium at 2.7 mM and 0.3% (w/v) BSA showed the highest fertilization rates compared to 15 μM progesterone, 50 mM heparin, and 100 μM Lyso-PC. From these results, we found that 2.7 mM calcium and 0.3% (w/v) BSA were the most effective sperm capacitation inducers of mouse sperm for in vitro fertilization. From these results, we could identify that, among diverse sperm capacitation inducers, 2.7mM calcium and 0.3% (w/v) BSA were the most effective inducers for in vitro fertilization.
