Abstract

Recently, growing interest in vitamin D has emerged from findings that demonstrate a low vitamin D status in populations. Similarly, much interest has been shown in the role that anti-Müllerian hormone (AMH) plays in reproductive physiology. Considerable confusion as to whether vitamin D status is related to ovarian function can be found in the literature. Our retrospective study was performed from June 2014 to April 2015. Oocyte donors were recruited and stimulated under the antagonist protocol with gonadotrophin-releasing hormone (GnRH) agonist to trigger ovulation. In 851 stimulation cycles, we determined the association among serum total and bioavailable vitamin D levels, ovarian reserve and response to ovarian stimulation and the reproductive outcome in their recipients. We showed that vitamin D levels were unrelated to ovarian reserve or ovarian response after ovarian stimulation; in oocyte recipients, gestational outcome did not differ according to a donor's vitamin D serum status. No correlation was observed between serum AMH and vitamin D. Bioavailable vitamin D was not related to recipients' ongoing pregnancy rate. Highly prevalent vitamin D insufficiency neither impaired ovarian reserve nor response or oocyte quality in egg donors. No evidence was found for recommending the analysis of vitamin D status in oocyte donors.
