Calcifediol (25OHD) Deficiency and Its Treatment in Women's Health and Fertility.

Nutrients 2022 Apr 27;14(9). Epub 2022 Apr 27.

Academia de Ciencias Médicas de Bilbao, Gynecology and Obstetrics Service, Hospital Universitario Cruces, 48009 Bilbao, Spain.

Currently, there is abundant scientific evidence showing that the vitamin D endocrine system (VDES) is a highly complex endocrine system with multiple actions in different regions of the body. The unequivocal presence of vitamin D receptors in different tissues related to fertility, and to specific aspects of women's health such as pregnancy, undoubtedly implies functions of this steroid hormone in both male and female fertility and establishes relationships with different outcomes of human gestation. In order to review the role of the VDES in human fertility, we evaluated the relationships established between 25-hydroxyvitamin D (calcifediol) deficiency and in vitro fertilization, as well as aspects related to ovarian reserve and fertility, and commonly diagnosed endocrinopathies such as polycystic ovary disease.
