A study reveals that the higher the vitamin D level, the greater the chance of pregnancy following artificial insemination

An optimum supply of vitamin D is one of the success factors for so-called in-vitro fertilisation, artificial insemination in a test tube. The results of a scientific study by the Faculty of Medicine at Kocaeli University in Turkey reveal that the higher the concentration of vitamin D in the follicular fluid surrounding the ovum, the greater the chance of pregnancy. The study involved 84 infertile women who underwent in-vitro fertilisation. According to the study, the women with the highest levels of vitamin D in their follicular fluid had a better chance of a successful pregnancy following artificial insemination. The statistical calculation shows how for every increase in vitamin D levels by one ng/mL, the likelihood of a pregnancy rises by 6%.
"An average vitamin D level of 40 to 60 nanograms per millilitre of blood (40 - 60 ng/mL) is the scientific threshold above which vitamin D can best exert its positive effects. 90% of vitamin D is formed by the skin, its synthesis is activated by exposure to UV rays,” Ad Brand from the Sunlight Research Forum (SRF) explains, referring to an ideal vitamin D supply.

The Sunlight Research Forum (SRF) is a not-for-profit organisation based in The Netherlands. SRF’s aim is to help bring to the fore, the latest medical and scientific information on the effects of moderate UV exposure on man. It takes time, often decades, for new scientific ideas to be accepted and assimilated, first into the general body of scientific knowledge and finally into policy. We want to reduce this time to a minimum so that the benefits of research can lead to a better understanding of UV effects on man and will become available to the public without any unnecessary delay. We hope to provide policy makers with correct information on which to base national health policy and individuals with better information on which to base choices about their lifestyles.

New research and well founded ideas on moderate UV exposure both indoor and outdoor will be presented and discussed in the Sunlight Research Forum by people working in the health disciplines, by academics and by journalists.

Optimised supply of vitamin D prevents dental cavities
Veldhoven, 9 August 2011 (SRF) The risk of developing cavities can be significantly reduced through the optimised supply of vitamin D. A vitamin D level of at least 30 nanogrammes per millilitre of blood (30 ng/ml) encourages the body to produce its own anti-microbial peptides, including cathelicidins and defensins, which inhibit cavity pathogens. This was the result of a study carried out by William B. Grant, one of the best

Attested by a study among 70.000 women: the crucial aspect is sufficient UVB radiation; diet or food supplements merely have a supporting function. Regular sun exposure and a vitamin D-rich diet reduce the risk of developing breast cancer by around 32 to 43 percent. The deciding factor in prevention is exposure to adequate UVB rays. Admittedly food that is rich in vitamin D, such as fish, dairy products, eggs and certain
Sperm switch into top gear with the sun
Veldhoven, 19 May 2011 (SRF) Men who top up on vitamin D in the sun or in a solarium, give their sperm an advantage in terms of motility, speed and penetration force. This was the conclusion of a study conducted by scientists from the University of Copenhagen investigating the role of vitamin D in human sperm production. The scientists tested the quality of sperm from 300 men chosen at random and
Tanning provides greater protection from the sun
Veldhoven, 10 May 2011 (SRF). Allowing the skin to slowly become accustomed to UV radiation from sunlight by moderate tanning creates a protective effect. Studies repeatedly find that continuous sun exposure below the erythema threshold (when the skin begins to redden) is essential in helping the human body to build up its natural self-protection mechanism against UV ray overexposure. Pigmentation and the formation of the so-called “light callous” - a
