As a part of in vitro fertilization(IVF) for farm animals, IVF experiment was conducted using New Zealand white rabbits with their sperm capacitated in vivo. The effect of uterine conditions on sperm capacitation and effect of sperm concentration and fertilization media on IVF rate and implantation of in vitro fertilized ova were studied. The results obtained are summarized as follows; 1. Acrosomal reaction, noted after staining, of sperm recovered from ligated and intact uterus of capacitators was 83.0% and 65.7%, respectively. 2. IVF rate of ova inseminated with sperm from ligated uterus tended to be higher in DM or with higher concentration of sperm than in the modified F12 medium or with lower sperm concentration. Cleavage rate of fertilized ova for 48hr in DM was 31.5% for 106/ml and 30.0% for 104/ml of sperm and that in modified F12 medium was 26.0% for 106/ml and 22.3% for 104/ml of sperm. 3. Using the sperm from intact uterus, cleavage rate of fertilized ova showed same tendency as those shown with ligated uterus. The rate was 82.0% for 106/ml and 66.5% for 104/ml of sperm in DM and was 69.0% for 106/ml and 56.5% for 104/ml of sperm in the medium. 4. When normal ova up to 48hr after IVF were cultured for 4 days in either DM or modified F12 medium, ova developed to blastocyst stage showed higher rate in the groups of higher sperm concentration in the both media. The rate was 80.9% and 60.0% for 106/ml and 104/ml of sperm in DM and 91.7% and 71.4% for 106/ml and 104/ml of sperm in the modified F12 medium, respectively. 5. Rate of implantation after transfer of 4- or 8-cell embryos was 36.8%.
