How Vitamin D Impacts Fertility?

The Sunshine vitamin – more formally known as Vitamin D or calciferol – is responsible for increasing intestinal absorption of calcium, magnesium, and phosphate. Apart from that, it performs many other biological effects, ultimately ensuring our bone immunity, overall physical and mental health.


Rise in Vitamin D deficiency


A study in 2020 showed that nearly 76% Indians were suffering from Vitamin D deficiency, indicating that this public health problem is fast attaining epidemic proportions.  Data also suggest that Vitamin D deficiency has been on the rise in the past two years due to limited outdoor activities and minimal exposure to sunlight in the aftermath of the coronavirus pandemic.

Even though there is no conclusive evidence that firmly established this association, several studies indicate Vitamin D blood levels of 30 ng/mL or higher can improve chances of pregnancy. This is precisely why most fertility experts advise women starting IVF treatments to go on supplements and consume a diet rich in Vitamin D. In men, Vitamin D is linked to semen quality and sperm motility.

Poor Vitamin D levels during pregnancy is also associated with increased risk of preterm birth.

Vitamin D deficiency has also been associated with a number of fertility issues which include PCOS, endometriosis, uterine fibroids, abnormal sperm function. As far as the baby’s growth is concerned, Vitamin D is necessary for its normal bone health and immune function.

A woman with adequate Vitamin D is also less likely to face pregnancy complications such as fetal growth restriction, preterm labour, pregnancy-related hypertension and gestational diabetes.
