A small new study from Italian researchers, published in the Journal of Clinical Endocrinology & Metabolism, has found a surprising reason why in vitro fertilization (IVF) may not always work.
As Yahoo News UK reports, the researchers looked at IVF success rates in 154 women who were vitamin D-deficient and compared them to 181 women who were not deficient in the vitamin, and found that the women with sufficient vitamin D levels were twice as likely to have IVF success. And not only that—the women with healthy vitamin D levels were also more likely to have “high-quality embryos.”
“Our work is the largest study to date to examine how vitamin D affects fertility in women who are undergoing IVF,” one of the study’s authors, Alessio Paffoni, MSc, of the Ospedale Maggiore Policlinico in Milan, Italy, said in a statement.” He continued, “Although randomized clinical trials are needed to confirm the findings, our results certainly suggest that low levels of vitamin D contribute to infertility.”
The researchers defined a healthy or sufficient level of vitamin D as 20 to 30 nanograms per milliliter of blood.

Despite improving science and public awareness campaigns around fertility issues and ways to treat them, fewer women are seeking help when they are having trouble becoming or remaining pregnant, according to an analysis of federal data. In fact, the analysis shows, the number of women who are seeking help for infertility or recurrent miscarriages is actually on the decline. More from the Detroit Free Press:
“There’s always been this perception these things are on the rise when the data have never supported that,” says Anjani Chandra, lead author of the report, out Wednesday from the National Center for Health Statistics.
Findings are based on a survey of 22,682 men and women, ages 15-44, conducted from 2006 to 2010, but much of the focus is on ages 25-44, because that’s when the report says “infertility service use may be more prevalent.”
In that age group, 17% of women had ever used any infertility service, which the report says is “a significant decrease from 20% in 1995.” Among childless women of those ages who have current fertility problems, the drop from 56% in 1982 to 38% most recently is “significantly less” than in 1982.
Kurt Barnhart, president of the Society for Reproductive Endocrinology and Infertility, says the report confirms what he already knows.
“Fertility services are underutilized and not reaching everybody,” says Barnhart, an OB-GYN at the University of Pennsylvania in Philadelphia.
