Omega-3 and vitamin E may offer hope to infertile couples

fertility The figures make for alarming reading. Over the last 50 years, there has been a decline of almost 50% in the quality of human sperm, and a fall in semen volume of around 25%, while abnormal sperm counts show a marked increase1. It’s a long-standing problem, first flagged up in the 1970s, but unfortunately the warnings issued at that time were not heeded. We are now seeing the dramatic consequences: in France, for example, 1 in 4 couples is unable to conceive after 12 months of trying, a figure that has doubled in 20 years.
How can we reverse this trend? One study published a few months ago gave little cause for optimism. It showed that lifestyle factors (alcohol consumption, smoking, exercise) had only a limited effect. Suspicions have focused on the many chemicals and pollutants present in our environment such as DEHP which is found in various plastics and acts as an endocrine disruptor.

While research on genotoxicity supports such explanations, other studies show that it is possible to take action as an individual, particularly in terms of nutrition. One such study2 suggests that supplementing with omega-3 (such as the concentrate Super Omega 3 - 500 mg) and vitamin E (such as the formulation Gamma E Tocopherols) provides spermatozoa with significant protection from lipid peroxidation, a process from which they are under constant threat. Spermatozoa are fragile because their cell membranes are rich in omega-3 fatty acids which are highly susceptible to oxidation3 and thus need effective antioxidant defences. When these are overwhelmed, the membranes lose their fluidity 4 impairing the sperm’s ability to penetrate the egg5. Supplementing with vitamin E may therefore reduce the adverse effects of oxygen derivatives on these membranes 6, while taking fish oils provides the body with a fresh supply of omega-3 fatty acids to replace those that have been compromised.

These findings will undoubtedly provide new hope to the 15% of couples for whom pregnancy has still not occurred after two years of trying.
