The congress of the American Society for Reproductive Health, held in San Diego, has addressed, among others, an interesting topic on which the specialists do not come to an agreement, and it is the role of nutrition in fertility.
Thus, for example, in the congress there has been presented a research carried out by scientists of the School of Public Health of the University of Harvard, which reveals that the consumption of three daily rations of whole milk products has a negative effect on the quality of the semen. The authors of this work (very unrepresentative, since it was based on data from only 189 men between 19 and 25 years old), attributed this negative effect to estrogen from the cow that contains the milk.
Women undergoing in vitro fertilization treatment (IVF) who ingested more protein and fewer carbohydrates achieved higher pregnancy rates
However, more specific studies have also been presented at the congress, whose objective was to determine the influence of the daily diet of patients who are undergoing fertilization treatment. in vitro (IVF) on the results of said treatment.
In one of these works, Danish scientists found that women who ate more proteins and fewer carbohydrates had a higher number of fertilized eggs that reached the blastocyst stage and, as a result, achieved higher pregnancy rates.
In another work, the researchers selected those patients in IVF treatment who had admitted to eating more carbohydrates and less protein and taught them to modify their diet, so they ate more protein and less carbohydrates for two months, before starting a new treatment. of IVF. The result was that, after the variation of the eating habits of the patients, the blastocyst formation went from 19% to 45%, and the pregnancy rates from 17% to 83%.
In the opinion of Richard Reindollar, vice president of the American Society for Reproductive Health, the data from these studies show that there is still a great lack of knowledge about the effects that dietary micronutrients have on reproductive capacity, and that it is still a field to explore.
