In an in vitro model, the number of human sperm cells migrating to wells containing heparin was significantly higher than those migrating to control wells. In humans a statistically significant chemotactic effect was noted in a 0.05 mg/ml in incubation medium.
The presence of heparin (0.005 mg/mL) in BWW induces a statistically significant increase in spermatozoa concentration to 7.76 x 104/450 pL in experimental wells compared with 2.69 x lo4/ 450 pL of sperm cells in controls.
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.
