Vitamin D deficiency gives new clues about infertility.
Implantation failures and recurrent miscarriages can be related to a deficiency of this vitamin.
Third Patient and Endometriosis Specialist Meeting

A vitamin D deficiency can be behind implantation failures and recurrent miscarriages. This is one of the principal conclusions drawn from the Third Patient and Endometriosis Specialist Meeting held in Seville, in April, by the Ginemed Foundation and the endometriosis patient association, EsEndo.

Embryo implantation is key to the reproductive process, equally as important as the quality of the gametes (eggs and sperm) and of the embryos. As such, this phase is now the focus of – more and more – studies and research. “Vitamin D deficiency can cause immunological disorders, and these can lead to the embryo being identified as a foreign body by the immune system and its implantation being rejected,” explains Dr Elena Traverso, head of Ginemed’s Endometriosis Unit.

Yet, vitamin D not only affects the endometrium, but also the ovaries, the placenta and even male gametes (sperm). To ensure that a deficiency here will not cause problems Dr Traverso recommends: “given that a deficiency in this vitamin negatively affects the reproductive process, its levels should be monitored during assisted reproduction treatment and pregnancy – and if they are low, we recommend that a vitamin D supplement is introduced into the diet”.
