Vitamin D and fertility in men and women

Posted on: January 30, 2012   by  John Cannell, MD


Every year, billions are spent in fertility clinics; the result of which is often in vitro fertilization (IVF). About 5 years ago, I began receiving emails from a nurse practitioner in Indiana who works in a fertility clinic. Her experience was dramatic; 5,000 IU/day for both the man and woman frequently resulted in a healthy baby. However, her last email to me was quite sad, she was in danger of losing her job as her boss, a gynecologist, was losing money due to vitamin D. He ordered her to stop advocating it or lose her job.

    A few years ago I had a client who had polycystic ovaries. At the age of 25 she had experienced about three periods in her whole life. She wanted to get pregnant, and we worked on a number of issues, but still no periods. I then discovered vitamin D, and suggested she take 10,000iu per day. She got pregnant that month, never having established her periods. She has consistently taken vitamin D, and recently delivered her third healthy child, but still is technically infertile, having only very occasional periods.

    Yes, agree, vitamin D fertility improves with vitamin D

    There is an interesting write-up of this research here: http://www.nhs.uk/news/2012/01January/Pages/vitamin-d-fertility.aspx

    This is part of the Behind the Headlines service run by the UK National Health Service: http://www.nhs.uk/news/Pages/about-behind-the-headlines.aspx

    The piece concludes by saying:

    “The researchers noted that there was a real lack of human controlled studies. As a result, 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.”

    Cheers, Andre

      Thanks Andre.

      I’ve got a question for our members and people reading this comment. Please read the write-up Andre linked to, again: http://www.nhs.uk/news/2012/01January/Pages/vitamin-d-fertility.aspx

      Do you like NHS’s more systematic approach in the review of the study, or do you prefer Dr. Cannell’s commentary and some things that stand out to him in the paper?
