PSMA5 and RARRES1, seminal plasma protein markers of sperm DNA fragmentation, are not altered by smoking

PSMA5 and RARRES1, seminal plasma protein markers of sperm DNA fragmentation, are not altered by smoking
Sperm DNA fragmentation is one of the major cellular mechanisms of male infertility and can be observed in 20% to 25% of infertile men. An earlier study has found that RARRES1 and PSMA5 proteins are altered in seminal plasma in men with high DNA fragmentation. Another study has shown that smokers present high sperm DNA fragmentation. Therefore, in this study, we wanted to evaluate whether these proteins are also altered in other causes of infertility, such as smoking.
