It’s crazy how important Vitamin D is for our systems. It’s classically involved in bone health but also influences inflammation, cancer risk, sugar metabolism, autoimmune disorders and of course mood. A new study released in April 2020 describes the role that vitamin D levels can have in supporting fertility. Both men and women have vitamin D receptors in reproductive tissues. In men this may play an early role in s***m production. Women have vitamin D receptors in the o***y, fallopian tube cells, walls of the uterus and in the placenta during pregnancy. It may influence both egg health and a healthy uterine lining. Vitamin D also plays an important role in estrogen and progesterone production.
PCOS (poly-cystic ovarian syndrome) - During fertility treatments, Vitamin D supplementation decreased inflammatory markers, improved insulin resistance and helped increase the number of mature follicles at ovulation. Higher vitamin D levels also appear to increase the chance of ovulation and pregnancy in PCOS.
ENDOMETRIOSIS - Vitamin D receptors in the uterine lining can regulate local inflammation and immune response, but it is not yet known though if Vitamin D actually makes endometriosis worse. Some human and animal studies suggest that decreasing stimulation of these receptors can improve symptoms although evidence is mixed.
S***M HEALTH - Low vitamin D levels have been correlated with decreased testosterone, low s***m motility and poor overall s***m quality, although supplemention with Vitamin D in studies does not seem to increase pregnancy rate.
FEMALE VITAMIN D AND IVF - Some research suggests that women who have appropriate levels of Vitamin D get pregnant more often, and this may even holds true during IVF. Making sure to bring your vitamin D levels up to par before an IVF cycle certainly doesn’t hurt, and it may increase the chance of pregnancy, especially if you have PCOS.
Get your vitamin D levels tested with an ND to know if you are deficient and determine how much you need to take!
