Smoking may have negative effects on sperm quality

Smoking may have negative effects on sperm quality
A recent study found that that sperm of men who smoke has a greater extent of DNA damage than that of non-smokers. Researchers also assessed 422 proteins in participants' sperm. One protein was absent, 27 proteins were underrepresented, and 6 proteins were over-represented in smokers. Analyses of these proteins suggest that cigarette smoking may promote an inflammatory response in the male reproductive tract.
