Demonstration of Specific Binding of Cocaine to Human Spermatozoa

Abstract excerpt

Exposure of males to cocaine has been linked to abnormal development of their offspring. To investigate the possible role of sperm, this study examined the interaction of cocaine with human spermatozoa. Washed sperm were incubated with tritiated cocaine (6.7 nmol/L) with or without unlabeled cocaine (670 mumol/L), and the samples were filtered and the remaining radioactivity quantitated. The specific binding was...
