Quantification of urinary gonadotropins by specific assays may improve the evaluation of sex‐specific hormonal changes in early infancy

The aim of this study was to investigate the feasibility of different gonadotropin assays for determining total and intact luteinizing hormone (LH), and follicle-stimulating hormone (FSH) immunoreactivity in urine (U-LH-ir and U-FSH-ir, respectively) during early infancy.
