L-carnitine fumarate, L-acetyl-carnitine and other components in male infertility: A pilot study of nutraceutics on sperm motility

The aim of this study was to evaluate any possible effect a combination of L-carnitine, fumarate, acetyl-Lcarnitine, fructose, citric acid, selenium, coenzime Q10, vitamin C, zinc, folic acid and vitamin B12 (Proxeed®) on sperm motility in a group of patients with unexplained asthenozoospermia. Thirty two patients received 1 sachet/day of Proxeed® for three months. Sperm parameters were studied before, during and after this treatment. Motility was also studied by the means of a computerized analysis (CASA system). The results of this study indicate that Proxeed® is able to increase sperm motility, both in a quantitative and qualitative manner. We conclude that oral administration of Proxeed® may improve sperm quality, at least in patients with idiopathic asthenozoospermia.
