Introduction The gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH) are released from the gonadotropic cells in the anterior pituitary gland. In men, the main target cells for LH are Leydig cells with subsequent

), luteinizing hormone (LH) and follicle-stimulating hormone (FSH) were determined with a chemiluminescent immunoassay (Immulite 2000 XPi Analyzer; Siemens Healthcare). Within and between assays, coefficients of variation for the applied method ranged from 1.2 to

gonadotropins, in particular luteinizing hormone (LH), after stimulation with GnRH or GnRH analog (GnRHa) is the standard method to confirm HPG activity ( 2 , 3 , 7 ). Currently, the value of 5 IU/L is accepted as the cut-off point when LH is determined by
