The ‘Behind the Headlines’ service from NHS Choices has featured a quality assessment of press reports that a “sunny break may be alternative to IVF” (reported by the Daily Mail; 30th January 2012).  The report was based on a systematic review of any type of study related to vitamin D and fertility.  The authors of the review note that there is a lack of human data available in this area, and that the studies included in the analysis were mainly animal or observational studies. 

The authors of the review comment that it is difficult to draw conclusions on the implications of these data for people, and it is not possible to say that fertility problems in men and women could be helped by vitamin D supplementation, increasing vitamin D through diet or spending time in the sun.
