From: The reproductive success of bovine sperm after sex-sorting: a meta-analysis
Comparison of Non-Return Rates (NRR) 24/60, pregnancy rates and calving rates after insemination with sex-sorted and conventional sperm. NRR, pregnancy rates and calving rates are significantly reduced after sex-sorting. The differences in the rates become more obvious with progression of pregnancy and reach the highest values in the calving rates. Overall, sex-sorting of sperm results in a 13% (9 percentage points) decrease of the NRR , a 23% (12.3 percentage unpoints) decrease of pregnancy rate and a 24% (13.3 percentage points) decrease of calving rate.
