Participation of vitamin D endocrine system in human fertility Vit D and fertility

Abstract

Interest is growing in the knowledge of the mechanisms of action of vitamin D in very different areas of pathology. In recent years, very different actions of vitamin D have been discovered. Far from being a simple vitamin, it is a hormonal complex that acts in very different parts of the body equipped with hormonal receptors for vitamin D. It controls more than 900 different genes making it. It represents up to 3% of the total human genome. There is a deficit in levels of 25 (OH)D in populations around the world, including young couples affected by fertility problems. In the field of infertility, it has shown beneficial actions on the evolution of polycystic ovary syndrome. It is capable of decreasing the growth of uterine fibroids and correlates well with anti-Mullerian hormone. It has also been shown to improve oocyte quality and the embryo implantation rate in assisted reproduction: Its adequate levels in pregnancy reduce the risk of gestational diabetes and improve perinatal outcomes: The objective of this manuscript is to review the most important aspects that relate to the endocrine system. of vitamin D with fertility and pregnancy.
