Background: C-peptide consists of 31 amino acids, synthesized in the beta cells of the pancreas and co-secreted along with insulin. Hence, serum C-peptide may be the preferred diagnostic biomarker for evaluating beta cell function compared to insulin. The urinary C-peptide to creatinine ratio (UCPCR) recently gained attention as a non-invasive biomarker for evaluating and monitoring metabolic risk. In this study, we aimed to characterize guiding values of UCPCR in healthy indi...

Anti-Müllerian hormone (AMH), known for its role in fetal development and female reproduction, is also present in adult and elderly men in considerable amounts. In recent years, controversial findings regarding relations to age, other hormones, and BMI (possibly based on a dilutional effect due to higher blood volume) have been discussed. To date, little is known of its clinical relevance in this population. We aimed to further investigate AMH levels in an aging male popu...

Background: A negative relationship between body mass index (BMI) and serum Anti-Müllerian hormone (AMH) levels has been previously reported. Whether this is because of an adverse effect of adiposity on AMH production or the hormone’s dilution in a higher blood volume that accompanies larger body size (‘hemodilution’) is not yet clear. Blood volume can be estimated by body weight, body surface area (BSA) or lean mass (LM). Of note, adipose tissue is poorly ...
