Clinical Reproductive Protocol

  • ✓Oocyte Maturation: Canine eggs ovulate as primary oocytes and require 48 hours in the oviduct to become fertilizable.
  • ✓Fresh / Side-by-Side AI: Perform 48 and 72 hours post-ovulation.
  • ✓Frozen Semen (TCI / Surgical): Perform 72 hours post-ovulation when eggs are fully mature (shorter sperm lifespan).
