Are GnRH and FSH potentially damaging factors in the cardiovascular system?

Abstract

In the physiological view the human cardiomyocytes express receptors of gonadotropin-releasing hormone and follicle-stimulating hormone. The local effects of these hormones in the heart are related also to some interstitial cells, such as endothelial cells with follicle-stimulating hormone receptors and immune cells with gonadotropin-releasing hormone receptors. The administration of androgen deprivation therapy in patients with prostate cancer is associated with increased incidence of cardiovascular complications. It is suggested that negative action of this therapy on cardiovascular system is due to the loss of testosterone but also levels of gonadotropin-releasing hormone and follicle-stimulating hormone are changed by therapy. In this article we review the literature to date with an emphasis on recent investigation focused on potential role of abnormal gonadotropin-releasing hormone and follicle-stimulating hormone levels induced by gonadotropin-releasing hormone agonists on the cardiovascular risk. These facts exacerbate the complexity of specific hormone and cell relationships within heart and vessels. Androgen deprivation therapy reveals the physiological relationships between hormones and specific tissues that are not part of the endocrine system.
