Vitamin D and Infertility


In northern countries, which have long, cold, dark winters, couples are less likely to conceive in the winter. Conception rates peak in the summer when the sun is bright outside.

There are several factors that indicate why this happens, but a prominent one is the availability of vitamin D to those who are trying to get pregnant.

Vitamin D is a steroid hormone that influences almost every cell in the body and has positive links to helping problems involving cancer, heart disease, and even fertility.

Get Your Vitamin D Checked if You Are Struggling with Infertility

Vitamin D is so important to health that those who are experiencing infertility should get their vitamin D levels checked. A new study has concluded that exposure to sunlight boosts fertility in both men and women. The researchers that conducted this study wrote in the European Journal of Endocrinology:

  • Vitamin D appears to impact in vitro fertilization outcomes, polycystic ovary syndrome, endometriosis, and levels of both estrogen and progesterone in women. These factors, positively influenced by Vitamin D, improve the likelihood of a women conceiving.
  • Vitamin D is essential for men to develop healthy sperm cells, and helps maintain a proper sperm count and good semen quality. Vitamin D also increases testosterone and consequently may boost men’s libidos.

Low Vitamin D Levels Have Been Previously Linked to Infertility

In 2008, the Austrian fertility specialist Dr. Anne Clark found that a third of 800 infertile men she tested had lower than normal vitamin D levels. 100 of the men who agreed to enhance their lifestyle by minimizing caffeine and alcohol intake, quit smoking, lose weight, and eat healthy for 3 months prior to fertility treatment, 11 of them were able to achieve pregnancy naturally.

A study published in November 2009 even confirmed that human sperm has vitamin D receptors. Analysis of sperm found that vitamin D is produced locally within them and that the vitamin may be used to signal other cells in the reproductive system. According to the researchers, the study revealed that Vitamin D had an unexpected and unprecedented role in fertilizing ability.

What Other Factors Could be Influencing Your Fertility?

It is estimated that 1 in 6 American couples struggle with getting pregnant every year. Evidence suggests that lifestyle, diet, and environmental exposures are in large part to blame. We are exposed to hundreds of toxins each day, certain prescription drugs deter conception, and vitamin deficiencies sometimes influence whether a couple can get pregnant. Here are a few strategies to consider when trying to get pregnant:

  • A healthy diet, rich in healthy fats and antioxidants as well as low in grains and sugar provide the optimal nutrients to become pregnant. Reducing grains and sugars (especially fructose) in a diet prevents insulin from resisting fertility in any way.
  • Genetically modified foods contain high concentrations of the herbicide glyphosate (found in Roundup), which has proven in studies to negatively influence fertility.
  • Chemicals should be avoided. Many everyday chemicals like MSG, fluoride from drinking water, phthalates, and Bisphenol are detrimental to reproductive health.
  • Electromagnetic fields like those from cell phones have been proven to negatively affect sperm quality. A certain study found that men who talked on the phone for more than 4 hours a day had the least healthy sperm compared to their contemporaries.

Vitamin D’s Incredible Influence

The human body has 30,000 genes, and vitamin D plays a vital role in keeping 3,000 of them healthy. If getting outside more often isn’t much of an option, you can boost your intake of vitamin D with a supplement made from a fatty fish like salmon. We recommend Kyani Sunset or Puritan’s Pride. Considering the benefits of Vitamin D and especially its influence on fertility, future parents would be wise to watch their consumption and expose themselves to more Vitamin D.
