Introduction: We aimed to establish an efficient in vitro fertilization (IVF) system without optimization of sperm concentration of individual bulls, which can obtain stable fertilization and development. We examined the effects of PHE mixture (20 μM D-penicillamine, 10 μM hypotaurine, and 1 μM epinephrine), theophylline (2.5 mM), and sperm concentrations (1, 2, or 5×106 spermatozoa/ml) on fertilization and development of bovine oocytes ...
