Abstract
We compared the abilities of two commonly used semen preparation techniques to decrease the amount of benzo(a)pyrene-diol-epoxide (BPDE)-DNA adducts in the spermatozoa of ten smokers. Semen processing by swim-up or discontinuous gradient centrifugation recovered spermatozoa showing an equally significantly lower amount of BPDE-DNA adducts than in unprepared spermatozoa from neat semen.
