Impact of Vitamine D Status on in Vitro Fertilization Outcomes (DFIV)
23. juni 2026 oppdatert av: Nantes University Hospital
Evaluation of the Impact of Vitamine D Status on in Vitro Fertilization Outcomes in a Large Population of Infertile Women.
Non skeletal effect of vitamin D have been the focus of much interest in the past decade.
During the last years, special attention has been given to the impact of vitamin D on human reproduction.
Its receptor is expressed in most reproductive organs including hypothalamus, pituitary gland, uterus, ovary, mammary gland and the placenta.
In vitro experiments suggest that vitamin D would be involved in regulated embryo-implantation.
Concerning AMH, vitamin D seems to alters AMH signaling in human granulosa cells although their circulated levels are correlated in lated reproductive aged women.
The results of precedents studies about the impact of vitamin D on IVF outcomes remain conflicting The aim of our study was to assess in a large unselected population of infertile women, the impact of vitamin D deficiency on IVF outcome and to examine the relationship between serum vitamin D levels and the ovarian reserve marker AMH.

Detaljert beskrivelse
Vitamin D was measured on the sixth day of stimulation. According to vitamin D level, women were divided into 2 groups (deficiency when 25(OH)D <20 ng/ml and sufficient when 25(OH)D >20 ng/ml).
Pregnancy rates were compared among these two groups after controlling age, BMI, characteristics of ovarian stimulation, number of ovocytes obtains, etc.
