Women in MAP with vitamin D-rich diets have a higher birth rate than those with vitamin D deficiency, according to researchers at Oxford University.
Vitamin D and pregnancy
Vitamin D deficiency had previously been associated with a high risk of poor embryo implantation and complications during pregnancy, such as fetal growth problems. However, the effect of vitamin D on conception and the beginning of pregnancy in the case of couples in MAP is still little known.
Many studies have been conducted on this subject. Indeed, more than 11 studies including 2700 women were able to give results on the association between vitamin D and medically assisted procreation (MAP).
Of these 11 studies, 7 showed that the birth rate was higher among women who took vitamin D than women with inadequate vitamin D levels. 5 studies have also shown that women with good levels of vitamin D are more likely to get pregnant than others.
All of these studies also showed the importance of vitamin D in MAP pregnancies: the women most likely to become pregnant through a clinical procedure were those who took vitamin D supplements.
