Abstract:Herein, the microfluidic device technique was used to investigate the effects of GDF‐9 concentrations and exposure time on the ram sperm positive rheotaxis (PR). Semen was collected from six rams and utilized for PR, motility and sperm kinetic parameter analysis using a computer‐assisted sperm analysis program with controlled flow velocity following 0, 10, 20 or 30 min of incubation at 37°C with GDF‐9 (200 , 400 or 600 ng/ml; semen sample without GDF‐9 was used as a control). Results revealed that there was no… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
