How does vitamin D affect chances of gettingpregnant?

So I went two weeks ago to get tests done for me as a regular check up and by vitamin D came back low.  The Dr. prescribed high dosage of vitamin D for the next 6 months... how does not having enough vitamin D affect women who are ttc?

I just started the one pill a week treatment at the same dose. I am also ttc and hoping that this works because I heard it causes problems with not being able to get pregnant, so we will see.. Good luck

it has it's pros and cons... I need because I'm way low the normal range.  Only taking it once a week that equals out to what I need to get me where I need to be.   I'm already taking prenatals and my doctor said it wasn't enough.  I'll have to call my doctor I'm nervous now.

Be careful with Vit D. Below is the article I found. Some is good but too much is bad.

Your prenatal level of vitamin D may play a role in determining your health later in life. Sound far fetched? It may not be.

During pregnancy, the active form of vitamin D increases significantly, particularly in the second and third trimesters. During this time, the baby's bones are developing, as are the brain, the nervous system, and the other organs.

Recently, a review published in the journal "Nutrition Reviews" looked at the research about vitamin D and maternal, fetal, and infant health. Although much more research is required, it appears that vitamin D contributes to improving pregnancy outcomes, such as decreasing the risk of pre-eclampsia, and improving length of gestation, birth weight, and infant bone mineralization. It also appears that sufficient vitamin D in early life may decrease the risk of health problems later in life such as schizophrenia, brain tumors, asthma, multiple sclerosis, and autoimmune diseases such as type 1 diabetes.

These findings don't mean you should run to the local pharmacy for a mega dose of vitamin D. In fact, the article also warns of potential adverse effects of too much vitamin D on the cardiovascular system and allergies. Much is still to be learned and hopefully gained from further research. But here's what I can share as safe advice now:

If you are pregnant:

Take a prenatal vitamin. If you can't tolerate that, take a regular multivitamin. Look for one with at least 200 international units of vitamin D (the U.S. recommended daily allowance).
The current tolerable upper limit is 2000 IU. The Canadian Pediatric Society actually suggests that this level may be appropriate for winter pregnancies.
If you have infants/children:

Infants fed breast milk need a vitamin D supplement, 400 international units daily, according to a 2008 report of the American Academy of Pediatrics (AAP).
Infants fed formula need a vitamin D supplement until they are drinking at least a liter of formula daily. Again, the AAP recommends up to 400 international units to complement the amount in formula. Consult with your child's doctor or dietitian.
Older children drinking less than a quart of vitamin D-fortified milk daily need a vitamin D supplement, up to 400 international units daily.
Infants and children are at greater risk of toxicity — so be cautious with your dosing and administration.

Just found this article.... very informative!



Vitamin D While most folks associate vitamin D with  bone health, a little known fact is that it can also play an important role in fertility.  

In fact, a number of studies have shown that Vitamin D has a direct impact on the reproductive organs in both men and women.   In men, it works to help produce more testosterone, the hormone responsible for making sperm.  In women, vitamin D works directly on the ovaries, helping to regulate how estrogen is used to help egg follicles mature and grow.

Vitamin D also appears to play a role  in how estrogen acts in the uterus,  particularly in regard to development of the lining. In fact when vitamin D levels are low,  your uterus may not develop a lining sufficient enough to hold on to your embryo – which in turn frequently leads to very early stage miscarriage.

In fact, vitamin D is now considered such an important fertility nutrient,  one group of Yale researchers devoted an entire study to learning what happens when levels decline.  Here they studied 67 women who had problems conceiving – and found that 93% of them were low in vitamin D.  According to researcher Dr Lubna Pal, “ Of note, not a single patient with either ovulatory disturbance or polycystic ovary syndrome (PCOS)  demonstrated normal Vitamin D levels; 39 per cent of those with ovulatory disturbance and 38 per cent of those with PCOS had serum 25OHD levels consistent with deficiency. “

In another study, women who lost their menstrual cycle and were considered infertile  due to PCOS   resumed their periods and became pregnant when vitamin D levels were increased.  

If that were not enough to get you to run right out to the nearest health food store and stock up on vitamin D supplements,   consider this:   Vitamin D is intrinsic to controlling blood levels of calcium. And when calcium levels go down, the rate of PMS climbs!   More importantly, however, the reverse is also true – when calcium levels are sufficient,   PMS is reduced – and ultimately that means fertility can prosper!  

In studies conducted by  University of Massachusetts researcher Elizabeth R. Bertone-Johnson, ScD,   and published in the Archives of Internal Medicine,  it was learned that when the intake of both calcium and vitamin D is high, the risk of PMS is  significantly reduced. In fact, they found that women who ate just four servings a  day of low fat dairy or yogurt, or drank orange  juice fortified with calcium and vitamin D had up to a 40% reduced risk of PMS.

So what's the connection between PMS and  fertility? Well first, when PMS is under control you will simply feel better with far less stress – which in turn means that all hormone activity will be better balanced. But more importantly,  since PMS is a condition that is  underscored by a reproductive hormone imbalance,  reducing your risk of this problem also means helping to insure the proper hormone balance necessary for a quick and easy pregnancy.

Finally,   the very latest research shows that Vitamin D deficiencies may be linked to a higher rate of bacterial vaginosis (BV)  a very common  intimate infection that   has been linked to infertility. Indeed, not only can this infection create a hostile envioronment that can negatively impact sperm,  if left untreated, BV can quickly turn into a a much more serious condition known as PID – pelvic inflammatory disease.  This infection can easily  spread into  the  fallopian tubes,  ovaries and even the uterus  and not only  directly and immediately impact your ability to get pregnant, but also create scar tissue that continue to interfere with conception long after the infection clears.   Moreover, if you do happen to get pregnant while you have a BV infection,  it could increase your risk of miscarriage as well as lead to premature labor and a low birth weight baby.  

The  good news  : You  can dramatically reduce your risk of developing this infection  - and increase your fertility in the process - by simply keeping your vitamin D levels high.  How can this help? While doctors aren't completely sure,  many believe that vitamin D helps give a boost to the immune system, which in turn helps keep the natural bacteria found in the V zone from growing out of control.

Looking at the prescribed bottle it says Vitamin D 50,000IU 1.25MG to be taken once a week for the next 6 months.  Let's hope this helps me!!!!

I think it has something to do with building up the lining in the uterus so its receptive to implationation.  Not 100% sure...I'd be interested in other peoples thoughts too!
