title: Sperm selection by swim-up in terms of deoxyribonucleic acid fragmentation as measured by the sperm chromatin dispersion test is altered in heavy smokers.
abstract: Toxic habits and their relationship with male factor infertility have been a matter of investigation in recent years, and smoking is one of the most common lifestyle toxic exposures to harmful substances. The analysis of sperm deoxyribonucleic acid fragmentation after capacitation detected a detrimental effect produced by tobacco, and this deleterious effect alters the sperm swim-up selection process in smokers, although the molecular and cellular basis of this phenomenon remain to be elucidated.
