Vitamin D is a fat-soluble vitamin that plays an important role in the body. It controls the amount of calcium and phosphorus in the blood. Vitamin D aids the body in calcium absorption and may help to prevent many types of diseases and cancer. It may also play a crucial role in fertility.
Vitamin D is made in the skin after being exposed to sunlight. It is available in many supplemental vitamins, and a wide variety of foods have also been enhanced with Vitamin D.
Vitamin D has been heavily studied in recent years. Much has been discovered about its crucial role in the body. As vitamin D levels in the population are often very low, the concern over deficiency has risen. Beyond its role in strong bones and teeth, vitamin D plays a role in hormone functions and maintaining a healthy immune system. Recent studies have also found an association between vitamin D and fertility.
Researchers at Yale University have found an association between low levels of vitamin D and infertility. The study examined vitamin D levels in sixty-seven infertile women and found that almost all suffered from a deficiency of the vitamin. In another Yale study examining fertility treatment outcomes, researchers found that women becoming pregnant from the treatment were more likely to have higher vitamin D levels.
At the University of Wisconsin-Madison, researchers found vitamin D to have an affect on female rats and fertility. Although pregnancy could occur without the vitamin, more negative effects occurred during gestation and following birth for the baby rats. Litter size, weight, and viability were all affected by the presence or lack of vitamin D. The results of this study could lead to more being understood about the association in humans between vitamin D and fertility.
Vitamin D plays a role in many aspects of the body that may also affect fertility. Maintaining a healthy weight, having a strong immune system, hormone regulation, and calcium absorption are all affected. Vitamin D plays many roles in the body and its affect on fertility may be very complicated with many indirect and direct associations.
The link between vitamin D and fertility is not completely clear. More research needs to be performed to understand how exactly the two interact. It does appear from the research that does exist, that when attempting to become pregnant and throughout pregnancy, women will want to be sure their vitamin D levels are within normal range.
