Vitamin D deficiency is common in our country. Despite the high number of sunny days, there are many reasons for vitamin D deficiency, especially in women. The main reason for the deficiency of this vitamin, which is closely related to reproductive health, is not benefiting enough from the sun during the winter months. It is one of the biggest causes of infertility problem because vitamin D affects reproduction in both men and women. Vitamin D deficiency causes infertility and reduces the chance of getting pregnant in IVF treatment. A healthy human blood should contain approximately 20-30 nanograms of vitamin D per milliliter. Values below 20 nanograms are considered vitamin D deficiency.
What Foods Contain Vitamin D?
Although vitamin D can be synthesized from the sun, it must be supplemented with food. The body’s daily need for vitamin D cannot be met entirely from food. Therefore, it is extremely important to take advantage of sunlight. Oily fish such as tuna and salmon, and seafood such as mackerel and oysters are extremely rich in vitamin D. In addition, dairy products such as cheese and butter are known as vitamin D stores. Apart from these, eggs and potatoes are among the important sources of vitamin D. People who do not like seafood can meet their vitamin D needs from fish oil tablets. Fat-soluble vitamin D can be obtained in very small amounts from food. For this reason, it is not enough on its own and it is necessary to go out to the sunlight.
Effect of Vitamin D on Reproduction
It has been observed that the chance of success in IVF treatments of women with vitamin D deficiency increases in parallel with the normalization of vitamin D levels. According to studies, vitamin D deficiency reduces fertility and significantly reduces the chance of IVF. During IVF treatment, men should pay attention to their vitamin D levels, as it also affects testosterone secretion. Vitamin D deficiency during pregnancy causes gestational diabetes, pregnancy poisoning, premature birth, low-weight birth, and a foul-smelling and runny vaginitis called bacterial vaginosis. For this reason, expectant mothers should be exposed to the sun and take vitamin D during pregnancy.
