Embryo Transfer Success Evaluation
Embryo transfer (ET) success evaluation is the systematic assessment of pregnancy establishment and calving outcomes following embryo implantation. Developed by reproductive physiologists in the 1970s-1980s, the method measures conception rates, pregnancy retention, calving rates, and calf viability to quantify the efficacy of ET programs and identify factors affecting outcomes. Success assessment is critical for optimizing ET protocols and managing investment in breeding programs.
