The influence that certain factors may have on an in vitro pregnancy is not well known, but according to some studies, there is a relationship between vitamin B and the success of the in vitro technique.
A team from the University of Aberdeen (United Kingdom) has studied the relationship between vitamin B and certain genes with the in vitro technique. Apparently a high rate of this vitamin in the blood with homocysteine (an amino acid present in the body, its metabolism is linked to the metabolism of folic acid, vitamin B6 and vitamin B12), cause a high percentage of frustrated pregnancies.
We studied 602 women who underwent fertility treatment, measuring their vitamin B levels and 5 genetic variants that are related to this vitamin. The conclusions were that there was a greater probability of having a twin pregnancy and this risk is linked to serum folic acid levels. On the other hand, it was also detected that there is no correlation between levels of vitamin B or folic acid with the success of fertilization.
What they did discover is the presence of a gene that is involved in folic acid metabolism and that is associated with healthy embryos. The conclusion is that vitamin B does not help a good fertilization but it does increase the possibility of having twins in the event that fertilization has been viable.
