The objective of the study was to determine the effect of different bovine gamete coincubation times on fertilization and embryo development performance. In vitro matured COCs were co-incubated with sperm at a concentration of 1.5 × 10(6) spermatozoa/ml in TALP medium for 3 hours (T 3, n = 362), 6 hours (T 6, n = 358), or 18 hours (T 18, n = 350).
