Sperm migration through polycarbonate and nylon membrane filters was studied by the trans-membrane migration ratio method. Sperm crossed the former filters but not the latter because of the greater pore length and complexity of the relatively thick nylon membrane. Adhesion of spermatozoa to the nylon structure was also observed. Using the polycarbonate filter we were able to correlate trans-membrane migration with conventional motility and measure the effects of drugs on sperm motility.
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.
