Clinical studies continue to demonstrate that antioxidants, the amino acid,
l-carnitine, and minerals like
zinc an selenium help promote sperm motility and concentration. A recent (2007) FertilAid for Men study further substantiates these claims.
L-Carnitine plays a vital role in spermatogenesis & sperm development - and in ensuring the maintenance of sperm quality and vitality. L-carnitine supports the metabolic processes of sperm and therefore helps sustain normal motility.
