Vitamin D supplement increases the chance of IVF pregnancy

Feeling tired all the time, no time for that walk in the park on a bright sunny day,  are you going around several  IVF Centres, without success ?  “Vitamin D " might be the answer to all your above problems. Right, it sounds simple and irrelevant, but vitamin D deficiency is so common that, upto 80% of the population is affected.

Some studies even show that it can cause depression and increase the chance for schizophrenia. Our body requires Vitamin D to absorb calcium and a deficiency of Vitamin D will eventually lead to calcium deficiency and further complications. Vitamin D is a steroid hormone that is produced in the skin as a consequence of exposure to the sun, and it is also absorbed from certain foods. 

A new study published in the Journal of Clinical Endocrinology & Metabolism (JCEM) found that women who are deficient in vitamin D are half as likely to conceive with IVF compared to women without vitamin D deficiency. So if you are trying for a kid or planning for IVF, it’s a good idea to get yourself tested.

Vitamin D status is measured by a 25(OH)D blood test (25-hydroxyvitamin D), also known as calcidiol test. Optimal serum vitamin D is considered to be at least 75 nmol/L (30 ng/mL).

Vitamin D helps in production of good-quality eggs in the ovaries and improve the chances of successful embryo implantation in the uterus.

Among women, vitamin D appears to impact in vitro fertilization (IVF) outcomes, endometriosis and  polycystic ovary syndrome (PCOS). It also boost levels of progesterone and estrogen, which regulate menstrual cycles and improve the likelihood of successful conception.

PCOS and Vitamin D 

Vitamin D deficiency is common in women with polycystic ovary syndrome (PCOS), with the 67–85% of women with PCOS having the problem.  Vitamin D deficiency may worsen symptoms of PCOS, observational studies reveal that lower 25OHD levels were correlated with insulin resistance, ovulatory and menstrual disturbances, reduced pregnancy success, hirsutism, hyperandrogenism, obesity and increased cardiovascular disease risks. 

Male infertility and Vitamin D 

In men, vitamin D is essential for the healthy development of the nucleus of the sperm cell, and helps maintain semen quality and sperm count. Vitamin D also increases levels of testosterone, which may boost libido.

Methods to improve vitamin D 

The most natural and inexpensive way to get vitamin D is by exposing your bare skin to sunlight (ultraviolet B rays). Of course there are some regions in Europe and arctic where sunlight is a luxury, but even after living in a sunny zone lot of people does not expose their body to sunlight resulting in Vitamin D deficiency. These people have to go for vitamin D supplements. Vitamin D3 is a good way to get vitamin D if you can’t get enough sunlight, or if you’re worried about tanning your skin.

Our body gets most of the vitamins and minerals from the food that we eat. However, there are  few food items which naturally contain vitamin D. Even if it is present in the food, the  amount is negligible, so it’s almost impossible to get your  body requirement just from food.
