Details and patient eligibility


Infertility is a major health problem affecting up to 15% of couples of reproductive age globally. For several years, it was assumed that most reproductive problems could be attributed to the female partner, but research in recent years has demonstrated that males were solely responsible for 20-30% of infertility cases and contributed to 50% of infertility cases overall. The term ''male infertility'' does not constitute a defined clinical syndrome, but rather a collection of different conditions exhibiting a variety of etiologies. It is far increasingly known that reactive oxygen species (ROS) are of significant pathophysiological importance in the etiology of male infertility. ROS are highly reactive oxidizing agents belonging to the class of free radicals containing one or more unpaired electrons, which are continuously being generated through metabolic and pathophysiologic processes. It has been suggested that oxidants interfere with normal sperm function via membrane lipid peroxidation and fragmentation of nucleic acids, which result in sperm dysfunction. Due to the sperm cell membrane abundance of polyunsaturated fatty acids (PUFAs) and the capacity of sperm to generate ROS, human spermatozoa are highly susceptible to oxidative stress. Since growing evidence indicates that oxidative stress can be a primary cause of male infertility, non-enzymatic antioxidants play a significant protective role against oxidative damages and lipid peroxidation. In addition, micronutrients and antioxidants are often used with good results in men with idiopathic infertility. Keeping in view the main protection provided by seminal plasma antioxidants against oxidative damages, a previous study showed that the dietary management with an eight nutritional supplements' combination, similar to this study's product and containing antioxidants, achieved a significant improvement in sperm quality up to a completely normal semen analysis. Also, another study confirmed the hypothesis that the combination of individual nutritional supplements as described in literature showed significantly better results than the sum of the effects of single administration.
