Study links Vitamin D to sperm health

Study links Vitamin D to sperm health
Oct 19, 2008 2:09 PM
An Australian infertility study has revealed disturbing levels of vitamin D deficiency among men who are unable to impregnate their partners.
The discovery surprised Sydney researchers investigating the incidence of DNA fragmentation of sperm, a significant factor in male infertility.
DNA fragmentation includes cellular damage caused by infection, smoking and ageing.
Sunlight is the major source of vitamin D, which helps regulate levels of calcium and phosphorous to generate healthy bones.
Fertility specialist Dr Anne Clark screened the blood of almost 800 men with fertility problems, finding almost a third had lower than normal levels of vitamin D.
"In a significant number of these men, there were also elevated levels of homocysteine, an amino acid in the blood associated with cell toxicity, and deficiency in folate, which is essential for healthy new cells," said Dr Clark, medical director of the treatment centre Fertility First.
"Men in the study group who agreed to make lifestyle changes and take dietary supplements had surprisingly good fertility outcomes."
Dr Clark said the study's results were unexpected.
"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."
Dr Clark said concerns about skin cancer could be a contributing factor to vitamin D deficiency among men, along with work and lifestyle choices, avoiding too much direct sunlight exposure.
"If that is the case, one wonders if the outcomes in the study group also raise the possibility of significant vitamin D deficiency in the broader public, and its effect on fertility
levels," she said.
Of the 794 men tested, 58 per cent were shown to have high levels of DNA fragmentation, according to results to be presented at a national fertility conference in Brisbane on Monday.
About 100 of the men agreed to quit smoking, minimise or stop their intake of caffeine and alcohol, reduce weight and take a three-month course of vitamins and antioxidants before commencing fertility treatment.
Most significantly improved their sperm quality and 40% went on to achieve a clinical pregnancy, with 11 occurring naturally.
"The results clearly show that lifestyle changes and dietary supplements can be beneficial for the conception of a healthy on-going pregnancy," Dr Clark said.

Ray of sunshine for infertile males

Tuesday, 21 October 2008 Dani Cooper

Couples struggling to conceive should move their focus out of the bedroom and on to the beach, new fertility research suggests.
In a paper presented to this week's Fertility Society of Australia conference, Dr Anne Clark shows Vitamin D deficiency may play a major role in male infertility.
Clark, medical director at the Fertility First assisted reproduction clinic in Sydney, says blood screening of 794 men who visited the unit found more than a third of them had vitamin D deficiency.
They were also found to be deficient in folate and had elevated levels of homocysteine, an amino acid in the blood associated with cell toxicity.
Among the couples where the male completed treatment for their nutritional deficiencies, just over half conceived naturally or with minimal treatment.
The finding comes out of a study by University of Sydney doctoral student Laura Thomson who is investigating DNA fragmentation of sperm, a significant factor in male infertility.
DNA fragmentation of sperm is most often the result of cellular damage resulting from infection, smoking or advanced paternal age.
Clark says their findings add weight to a European study earlier this year that shows women's vitamin D levels strongly correlate with their ability to conceive.
Surprise

"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," she says.
She says concerns about skin cancer resulting from exposure to ultraviolet rays could be a contributing factor to vitamin D deficiency among men, along with work and lifestyle choices to avoid too much direct exposure to sunlight.
"The amount of sun needed is just 10 to 15 minutes a day outside the heat of the day," she says.
If workers had their morning tea break outside with their sleeves rolled up they would absorb sufficient vitamin D, Clark says.
In response to the screening results, Clark says 123 of the men agreed to a program that included changes in lifestyle and diet such as quitting smoking, reducing caffeine and alcohol intake, and losing weight.
The men were also asked to take antioxidants and a multi-vitamin for two to three months, Clark says.
She says the lifestyle changes led to a 75% reduction in the level of sperm fragmentation among the 123 men.
"We also observed improvement in the shape of sperm, which can enhance conception," Clark says.
Forty pregnancies had been achieved among the group, with more than half of those pregnancies occurring naturally or with minimal intervention such as intrauterine insemination.
Clark says there were only three miscarriages (6%) among those pregnancies.
This compares with an average 22% miscarriage rate among women using fertility treatment, she says.
She says the findings could have major implications on the costs of fertility treatment with one in six Australian couples experiencing infertility.
The blood screening test costs about $450 while a cycle of IVF treatment is about $4500.
