Follicle-stimulating hormone (FSH) is a member of the glycoprotein hormone family that plays a pivotal role in ovarian folliculogenesis and spermatogenesis. FSH receptor (FSHR) is, indeed, highly expressed in granulosa and Sertoli cells respectively. However, recent studies have detected FSHR also in extra-gonadal tissues, such as adipose tissue, bone, endometrium, placenta, endothelium, monocytes, and malignant tissues, suggesting, that the activity of this hormone may not be...

Purpose: Undercarboxylated-OCN (ucOCN), acting on the receptor GPRC6A, was shown to stimulate of testosterone (T) production in Leydig cells in rodents, in parallel with the hypothalamus/pituitary/gonadal axis mediated by luteinizing hormone (LH). Hence, reduced serum ucOCN and/or inactivating gene variants of GPRC6A, are supposed to affect testis function in humans. The aim of this study is to evaluate the association among serum ucOCN, rs2247911 GPRC6A gene polymorphism and ...

Purpose: Undercarboxylated-Osteocalcin (ucOCN), acting on its putative receptor GPRC6A, was shown to stimulate of testosterone (T) production by Leydig cells in rodents, in parallel with the hypothalamus-pituitary-gonadal axis (HPG) mediated by luteinizing hormone (LH). The aim of this cross-sectional study is to evaluate the association among serum ucOCN, rs2247911 polymorphism of GPRC6A gene and the endocrine/reproductive pattern in a cohort of infertile males, poss...
