This follows on an earlier work Vitamin D could correct men’s damaged fertility For decades lower levels of Vitamin D have been associated with unhealthy outcomes in women and children, but now a new Australian research suggests that men too are affected equally.

Researchers believe that a lack of sunlight, nicknamed the “sunshine vitamin” because of its unique ability of being produced by the body by exposure to the warm sun, may damage sperm and thus affect the male fertility.

800 men with fertility problems were enrolled in the new study. At the start, nearly 59 percent reportedly suffered nutritional deficiencies, including lower than normal levels of folate and vitamin D, analysis revealed.

As all the participants were undergoing fertility treatments to induce pregnancy in their partners, they were urged to take up lifestyle changes.

Of them, as many as 123 participants agreed to make lifestyle changes and to take dietary supplements for 2-3 months before starting fertility treatment.

Quitting smoking, reducing coffee and alcohol intake and taking a diet rich in folic acid and other vitamins were the foundation of lifestyle changes.

Three months on, almost three-fourth reported a significant reduction in the number of damaged sperm. Out of the lot, 36 couples successfully achieved a pregnancy with 18 not using any assisted reproduction technologies.

Highlighting the importance of the vitamin, Dr. Anne Clark, medical director of the treatment centre, Fertility First, noted, "Just like women, men too should monitor their pre-conception health."

"Thinking about getting pregnant is a combined project. Fertility is a couple issue, it's not a woman's issue. The traditional sort of foods that we ask women to eat to improve their chances of having a healthy baby, men need to be told the same. They make up half the baby, so they need to be making changes too," she added.

Vitamin D also plays a vital role in strengthening bone and fabricating healthy teeth. Moreover, besides its basic function of boosting the body’s calcium absorption, vitamin D also appears to play a significant role in upholding the immune system.

A chronic Vitamin D deficiency often shows up later as brittle bones and an undermined immune system making people more susceptible to auto-immune diseases, such as type 1 diabetes, multiple sclerosis and to certain types of cancers, researchers noted.

Remember that Sperm have got Vitamin D Receptors that means they must have a use for Vitamin D. The other place you find VDR is in the sperms target tissue. So both male and female will need to have optimum Vitamin d status to ensure both sperm and the tissue that sperm is heading for have D3 available.

PS uk average D3 status through the year is lower than the 75nmol/l ~ 30ng status in the above research regarded as normal. Remember also that normal is not the same as natural. The natural level our bodies attain and maintain if we naked lived as we evolved is 50~70ng or 125~175nmol/l at those levels breast milk flows replete with D3, our muscles achieve maximum strength, we have the greatest protection from chronic disease and least incidence of infection (colds and flu) Serum 25(OH)D can be expected to rise by about 1 ng/mL (2.5 nmol/L) for every 100 IU of additional vitamin D each day
2~3 drops daily of this Cheap UK source of effective strength D3 should be sufficient for most people
