Recent studies have shown that there are in many cases a link between sperm defects and miscarriage. Studies indicate that recurring miscarriages can be linked to sperm defects as these miscarriages take place because of genetic abnormalities in the embryo. Not all miscarriages result because of sperm defects or other genetic defects although the studies are seen as a breakthrough in medical science. By supplementing with PregAssist which contains Vitamins C and E as well as selenium to help improve sperm quality and L-Arginine to improve sperm motility, men reduce the risk of miscarriage because of sperm defects. The supplement also contains Beta Carotene to help with cell maturation and prevent ageing. As such it is possible to reduce sperm defects and their influence on pregnancy.
