Diet Influencing the Fertility in Humans

Abstract

Over the past decade, the studies of the relationship between diet and human reproduction has substantially increased, culminating in the discovery of a few simple trends. Supplemental folic acid intake, particularly at doses higher than those prescribed for the prevention of neural tube defects, has been consistently associated with lower infertility rates, lower risk of failure of pregnancy and greater progress in the treatment of infertility. In the other hand, vitamin D does not seem to play an important role in human reproduction in the absence of deficiency, in view of positive results from animal models. Antioxidant supplementation does not seem to provide any advantage to women seeking infertility therapy, although where the male partner is augmented, it tends to be of benefit. While it is uncertain to what degree the toxicity of shared food supplies, such as fish with high levels of environmental toxicants, will dampen this gain, long-chain omega 3 fatty acids tend to boost female fertility. Finally, commitment to balanced diets in favour of fish, meat, whole grains, fruit and vegetables is linked to increased female fertility and better male semen quality. The accumulated proof has also been stacked against common assumptions. Once suggested as reproductive toxicants, dairy and soy have not been reliably linked to poor fertility. Similarly, as results from massive, high-quality trials begin to mount, the evidence of a potentially deleterious impact on the capacity to become pregnant from mild alcohol and caffeine consumption looks less strong than it once did. Although a complete picture of nutrition's position in fertility is far from complete, there has been a lot of improvement.
