Vitamin D is a cluster of several steroid hormones that assist in the absorption of critical nutrients such as zinc, phosphate, calcium, iron, and magnesium from the intestine. These nutrients are essential for every organ of the body.
Sources of Vitamin D
Fortified food items: Dairy products such as milk, cheese, butter, and cream.
Sunlight: The best source of Vitamin D. Sunlight is absorbed by the skin, and Vitamin D is synthesized from the cholesterol present in it.
What Organs are Sensitive to Vitamin D?
The uterus, ovaries, and placenta formed during pregnancy are among the most receptive organs of the body for Vitamin D.
Vitamin D Deficiency and Pregnancy-Related Issues
Low levels or deficiency of Vitamin D have been associated with pregnancy-related issues such as:
Production of Estrogen: A considerable amount of Vitamin D in the body helps in increasing the production of estrogen, aiding the successful implantation of the embryo.
Healthy Pregnancy: Studies have shown that Vitamin D helps in the healthy progress of pregnancy, including the successful development of the baby and maintaining a healthy and sufficient uterine lining.
Symptoms of Vitamin D Deficiency
The best way to discover a vitamin D deficiency is to take a blood test that measures the level of the vitamin in your blood. Symptoms of Vitamin D deficiency can be vague and may include:
Importance of Vitamin D on Reproduction | IVF Success
Vitamin D plays a crucial role in reproductive health, as evidenced by scientific studies. Research using mice has highlighted its importance in the reproductive system:
Impact on Uterine Development
Mice that are deficient in vitamin D or lack the vitamin D receptor exhibit significant issues with uterine development. This underdevelopment can impair the uterus's ability to support a pregnancy effectively, which is crucial for successful implantation and fetal development.
Egg Quality
Vitamin D deficiency in these mice also leads to the formation of abnormal or immature eggs. Proper vitamin D levels are necessary for egg maturation, which is vital for fertility and successful reproduction.
Pregnancy and Fetal Development
Even if these mice manage to become pregnant, their fetuses often experience impaired growth. This suggests that vitamin D is important for the normal development of the fetus and that deficiencies can lead to complications during pregnancy.
Studies on Women Undergoing IVF
Women undergoing IVF provide valuable insight into the role of vitamin D. Each aspect of reproduction, from egg development to embryo implantation, can be examined. According to a new study, women with higher vitamin D levels than those with lower levels have a better chance of becoming pregnant through in vitro fertilisation.
