Washington DC: According to a new study, certain nutrients and dietary supplements can be beneficial for sperm quality and male fertility.
The study was published in the Journal of Advances in Nutrition. Infertility affects 15% of the world's population and is recognized by the World Health Organization as a global health problem.
In recent years, studies on sperm quality in different countries have shown a decrease that could have consequences for the survival of the human species. The decrease in sperm quality has been linked to unhealthy lifestyles. Stress, the use of drugs, tobacco, alcohol and unhealthy diets seem to be among the main factors.
Despite the current lack of scientific evidence regarding the effect of dietary and nutritional supplements on sperm quality, many fertility clinics offer dietary recommendations before offering their patients in vitro fertilization (IVF) or intracytoplasmic injection of spermatozoon (ICSI).
Recently, researchers from the Human Nutrition Unit of Rovira i Virgili University and the Pere i Virgili Institute for Health Research and researchers from the Clinical Department of Human Reproduction and Infant Growth at the University of Guadalajara (Mexico) conducted the largest analysis of clinical studies on the effects of different nutrients and dietary supplements on sperm quality and male fertility.
After qualitatively analyzing the results of 28 nutritional studies involving 2,900 participants, the researchers concluded that supplementation with omega 3 and coenzyme Q10 (in liquid or tablet form) could have a beneficial effect on the number of of sperm in the sperm. Supplementing the diet with selenium, zinc, fatty acids, omega-3 and coenzyme-Q10 is associated with an increase in sperm concentration, supplementing the diet with selenium, zinc, omega-3, Coenzyme-Q10 and carnitines have been associated with improvement in sperm mobility.
The study suggests that dietary supplements have a modulatory effect on sperm quality and provides a complete and up-to-date review of existing scientific evidence.
The results indicate that some dietary supplements may have a beneficial effect on sperm quality, although it remains to be demonstrated whether this increases the chances of conceiving a child naturally or through assisted procreation techniques.
