A study reveals that the higher the vitamin D level, the greater the chance of pregnancy following artificial insemination
(lifePR) (Veldhoven, )An optimum supply of vitamin D is one of the success factors for so-called in-vitro fertilisation, artificial insemination in a test tube. The results of a scientific study by the Faculty of Medicine at Kocaeli University in Turkey reveal that the higher the concentration of vitamin D in the follicular fluid surrounding the ovum, the greater the chance of pregnancy. The study involved 84 infertile women who underwent in-vitro fertilisation. According to the study, the women with the highest levels of vitamin D in their follicular fluid had a better chance of a successful pregnancy following artificial insemination. The statistical calculation shows how for every increase in vitamin D levels by one ng/mL, the likelihood of a pregnancy rises by 6%.
"An average vitamin D level of 40 to 60 nanograms per millilitre of blood (40 - 60 ng/mL) is the scientific threshold above which vitamin D can best exert its positive effects. 90% of vitamin D is formed by the skin, its synthesis is activated by exposure to UV rays," Ad Brand from the Sunlight Research Forum (SRF) explains, referring to an ideal vitamin D supply.
