Thanks to our great partners from the Nantes-Atlantic College of Veterinary Medicine (France), EVOLUTION and the Autonomous University of Barcelona (Spain), we are glad to announce our new publication in Veterinary Sciences Journal !
This paper evaluate the relationships between the sperm proAKAP4 levels measured by ELISA (Bull 4MID Kit), the conventional semen analysis, and fertility indicators (non-return rate at 90 days) in post-thawed conditions using commercially available straws.
Sperm protein proAKAP4 concentration can be used as a marker of post-thawed semen quality and of fertility in bulls. The
proAKAP4 concentrations were shown to correlate with progressive motility and to be associated with sperm motion variables and the 90-day non-return rates following cow artificial insemination.
The authors then stated that high concentrations of ProAKAP4 are then indicative of a good sperm quality and are a predictive parameter of male fertility as previously shown in other mammals.
