A recently published study shows the influence of too high meat intake in men on an IVF treatment. Moreover it is important, which kind of meat will be eaten by the male partner.
The study* which examined 141 men which were undergoing an IVF with their female partners from 2007-2014 showed that there is a relation between men’s meat intake and fertilization rates.
While the intake of poultry showed a positive influence on the treatment, a negative effect was detected when men were eating red or processed meat (sausages, cold cuts, etc.). Furthermore no connection was found between the amount of eaten meat and the outcome of the treatment.
This means that it is not the quantity but the type of meat that can negatively or positively influence the IVF treatment.
