An estimated 15% of Australian couples struggle with getting pregnant each year, and there’s compelling evidence that lifestyle, diet and environmental exposures are largely to blame. Not only are you exposed to hundreds (if not thousands) of toxins each and every day, but some of the most commonly prescribed drugs, poor diet, and common vitamin deficiencies have also been linked to reduced fertility, just to name a few.
As Iva Keene, author of the Natural Fertility Prescription, stated:
“Conventional IVF and other assisted reproductive technology (ART) treatments don’t address root causes of infertility. These root causes include: nutritional deficiencies, toxin exposure, stress, food intolerances, allergies and immune deficiencies. These subtle but critical factors interact synergistically to impact the quality of your eggs and sperm, affecting your ability to conceive and the health of your embryo.
… during the generation and maturation of gamete cells — sperm and ovum — that form an embryo [a period of 120 days], everything that you and your partner ingest, inhale or are exposed to will influence the health of your eggs and sperm for better or worse, and the ultimate quality of the genetic building blocks you pass onto your child. This is why it’s crucial to follow a good preconception plan for a minimum of 4 months before conception. A baby is a 50-50 product of his or her parents — therefore optimizing the quality of eggs and sperm is of paramount importance.”
Some of you may have heard of Vitamin D, some of you not. Vitamin D is a steroid hormone that influences virtually every cell in your body and has been positively linked to health conditions ranging from cancer to heart disease, and now, according to research, may significantly boost fertility in both men and women. A study published in The Journal of Nutrition found that in vitamin-D-deficient female rats, fertility was reduced by an astounding 75 percent, litter sizes were diminished by 30 percent, and there was impaired neonatal growth in offspring.
If You’re Struggling With Infertility, Get Your Vitamin D Levels Checked
Vitamin D is so crucial to health that we urge everyone to make sure their levels are optimized, but if you’ve been dealing with infertility, this is especially important.
As the researchers reported in the European Journal of Endocrinology:
- Among women, vitamin D appears to impact in vitro fertilization (IVF) outcomes, endometriosis, polycystic ovary syndrome (PCOS), the most common female endocrine disorder, as well as boost levels of progesterone and estrogen, which regulate menstrual cycles and improve the likelihood of successful conception
- 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
The researchers state:
“Given the high prevalence of infertility as well as vitamin D insufficiency in otherwise healthy young women and men and the possible role of vitamin D in human reproduction, research might lead to new therapeutic approaches such as vitamin D supplementation in the treatment of female and male reproductive disorders.”
Low Vitamin D Levels Previously Linked to Infertility
This is not the first time the “sunshine vitamin” has been linked to infertility. In 2008, Australian fertility specialist Dr. Anne Clark found almost one-third of the 800 infertile men included in her study had lower than normal levels of vitamin D, (bear in mind here that “normal” does not equal “optimal” — so by optimal standards, the rate of vitamin D deficiency was likely far higher than one-third) stating that:
“Vitamin D and folate deficiency are known to be associated with infertility in women, but the outcomes of the screening among men in our study group came as a complete surprise. Men in the study group who agreed to make lifestyle changes and take dietary supplements had surprisingly good fertility outcomes.”
In fact, of the 100 men who agreed to make and maintain certain lifestyle changes (quitting smoking, minimizing intake of caffeine and alcohol, weight reduction, along with a course of vitamins and antioxidants) for three months prior to fertility treatment, 11 of them went on to achieve pregnancy naturally, without IVF treatment.
Interestingly, another study published in November 2009 confirmed that human sperm does in fact have a vitamin D receptor. Analysis indicated that vitamin D is produced locally in the sperm, which suggests that vitamin D may be involved in the signaling between cells in the reproductive system. According to the authors, the study revealed “an unexpected significance of this hormone [vitamin D] in the acquisition of fertilizing ability,” and the results imply that vitamin D is involved in a variety of sperm signaling pathways.
What Else Might be Impacting Your Fertility?
There are numerous factors involved in fertility problems which we have written about previously. Toxicity can be a big part of the picture. Sugar consumption also impairs fertility. Hormonal and period problems can be a big part of infertility. Problems in sperm quality. Nutritional defiencies. Stress. The list goes on and on. Here are a few initial do-it-yourself strategies to consider
Are You Ready to Optimize Your Vitamin D Levels?
This is an imperative step for anyone planning a pregnancy, not only for increasing the rate of conception but also for the benefits it offers during pregnancy. Vitamin D deficiency is currently at epidemic proportions, largely because people do not spend enough time in the sun to facilitate this important process of vitamin D production.
So the first step to ensuring you are receiving all the benefits of vitamin D is to find out what your levels are. The point of vitamin D testing is, of course, to be sure you are maintaining a therapeutic level of vitamin D in your blood. A few years back, the recommended level was between 40 to 60 nanograms per milliliter (ng/ml), but more recently the optimal vitamin D level has been raised to 50-70 ng/ml.
To get your levels into the healthy range, you have two options. One is sun exposure, since vitamin D is produced by exposure to it. You will need to expose a large amount of your skin until it turns the lightest shade of pink, as near to solar noon as possible, in order to typically achieve adequate vitamin D production. If sun exposure is not an option, vitamin D3 supplement can be taken orally. Research suggests specific dosages in order to elevate vitamin D levels above 40 ng/ml, which is the absolute minimum for disease prevention. Speak to one of naturopaths about your vitamin D levels and what supplementation dosage you may require depending on your vitamin D levels.
Infertility can be a challenging condition with multiple contributing factors, but you have nothing to lose and everything to gain by optimizing your vitamin D levels. It is free if you do it via sun exposure, and inexpensive if you use a vitamin D3 supplement. It’s a simple step that can have a profound impact on your health, even if trying to conceive naturally is not your primary goal.
