In this study, we examined the rates of <I>in vitro</I> fertilization within and among five inbred strains (BALB/cA, C3H/HeJ, C57BL/6J, DDD, NC) of mice. The rates of fertilization was significantly low when C3H/HeJ eggs were inseminated with BALB/cA spermatozoa (68 %), but other combinations resulted in high fertilization rates (88-100%). The rates of polyspermic eggs were different among various combinations of strains, being low with spermatozoa from BALB/cA and C57BL/6J, as compared with spermatozoa from C3H/HeJ and NC: and low with eggs from C57BL/6J, but high with eggs from BALB/cA, DDD and NC
