摘要: Abstract In vitro trials on the survival of sperm stored fresh or rediluted after freezing showed quite significant differences in total time incubated at 37°C. Even adjusting for different concentrations, was still superior compared with frozen (124 ± 5.5 h vs. 75.8 3.1 h). There no difference fertility between (RDF) and sperm, both Caprogen, when insemination dose 20 × 106 2.5 respectively. Reduction concentration from to 5 RDF 0.5 semen reduced non return rates by 7.9% 7% respectively (P
