Background: Oxidative stress is implicated in the pathogenesis of primary male infertility. Some studies suggest that administration of the amino acid derivative anti-oxidant, L-carnitine, may improve sperm quality. No previous study has investigated whether the anti-oxidant effects of L-carnitine relate to changes in sperm quality in men with infertility.Aim: Investigate whether L-carnetine significantly improves sperm function, and whether baseline lev...

Background: Recurrent pregnancy loss (RPL) affects 1–2% couples, and is defined as ≧3 consecutive pregnancy losses before 20-weeks’ gestation. RPL is caused by foetal chromosomal abnormalities, or maternal factors such as thrombophilia. It was recently reported that men with RPL have high levels of sperm DNA fragmentation (a marker of infertility); however, the cause of this damage is currently not known. Seminal plasma has high levels of granulocyte-derived o...
