Does using vitamin D for fertility help in men?
It is known from animal studies that a deficiency in vitamin D impairs the fertility status. Specifically, a low level of vitamin D reduces sperm count and causes low sperm speed in rodents and mice.
Lab studies have shown that human sperm cells have receptors that bind and respond to the presence of vitamin D. Hence, researchers believe that the vitamin D can influence the development and action of the sperm cells.
But are there any scientific studies to actually show that a deficiency in this vitamin actually affect sperm quantity and quality?
Read on to find out what experts have discovered about the effects of vitamin D on sperm cells...
Vitamin D is positively associated with sperm motility and increases intracellular calcium in human spermatozoa.

This is one of the more recent studies where researchers looked for a link between vitamin D and fertility status in men.
Three hundred men were selected from the general population and their serum vitamin D levels were determined. Also, from these 300 men, 40 of them provided semen samples for sperm analysis.
Here's what they discovered:
Of these 300 men, 40% of them were deficient in vitamin D.
Blood levels of vitamin D were directly and significantly related to sperm motility.
Blood levels of vitamin D were also related to the quality of the sperm cells. (Scientists call that sperm morphology. In other words, are the sperm cells are normally shaped?)
Moreover, and perhaps as important, vitamin D seems to increase the sperm's ability to penetrate and fertilize the egg.
(Vitamin D seems to increase the acrosome reaction, the tip of the sperm cell that starts a chemical reaction so that it can deposit the genetic material in the egg to fertilize it.)
Other previous lab studies have suggested a relationship between poor sperm quality with a deficiency in vitamin D.
This study provides compelling evidence that blood levels of vitamin D has a direct effect on the quality and quantity of human sperm cells.
In addition to taking vitamin D supplements, two helpful products come to mind that are used to boost fertility and promote better reproductive health. Each one is specifically formulated to match to the biological needs of a man and a woman.
Fertile XX is a natural product formulated to enhance fertility in women. It will support the female reproductive system, maintain the menstrual cycle and support regular ovulation and egg production.
Fertile XY is a natural product formulated to meet a man's reproductive needs. It promotes prostate health, increases sperm count and motility, enhances libido and supports a healthy erection.
Both are custom formulated by a well-known and highly respected manufacturer of natural remedies. They are so confident of the quality of their products that they offer a 100% one-year money-back guarantee. You have nothing to lose.
Should I consider taking vitamin D for fertility enhancement?
Yes. A low level of vitamin D is shown to reduce sperm motility. It also seems to impair the mechanism by which a sperm cell penetrates and fertilize the egg.
We suggest for men to take 1,000 IU daily of vitamin D for fertility enhancement and well as for general health. If possible, get your serum vitamin D levels measured.
The popular all natural products Fertile XX and XY can be safely used with vitamin D to further enhance fertility in both men and women.Get More Info on Fertile XX and XY
