Adipocytokines Delay Pubertal Maturation of Human Sertoli Cells

Wagner Isabel V. , Yango Pamela , Svechnikov Konstantin , Tran Nan D. , Soder Olle

Background: Obesity and metabolic syndrome related co-morbidities are increasingly recognized in children. Reproduction is an important target of obesity complications, including adverse effects on spermatogenesis and steroidogenesis in males. Adipocytokines are key players in various complications of obesity.Objective and hypotheses: The aim was to study the potential effects of adipocytokines on Sertoli cell function and possibly link the findings to t...

Adipose Tissue – A Source of Hyperandrogenism in Obese Females?

Wagner Isabel V. , Sahlin Lena , Savchuk Iuliia , Svechnikov Konstantin , Soder Olle

Background: Obesity in females is often associated with metabolic complications and hyperandrogenism. However, the source of androgens is not entirely clear.Objectives and hypotheses: Our objective was to find out if adipose tissue (AT) is a site of steroid production during childhood and adolescence, and if this source could add to hyperandrogenism in obese females.Methods: Parametrial and inguinal adipose tissue was collected and...

Childhood Obesity Negatively Influences Adult Leydig Cell Function

Wagner Isabel V , Kloting Nora , Kiess Wieland , Soder Olle , Svechnikov Konstantin

Background: Childhood obesity is a global health problem and co-morbidities develop already during childhood and adolescence. Male obesity impacts negatively on reproductive function. Testosterone is decreased, sperm quality reduced, and the physical and molecular structure of germ cells altered in obese males. However, less is known about the role of prepubertal obesity on future reproductive function. We therefore explored Leydig cell function and reproductive potential in a...

Insulin-Like Factor 5 –A Novel Orexigenic Hormone in Humans is Dysregulated in Obesity

Wagner Isabel V , Flehmig Gesine , Scheuermann Kathrin , Loffler Dennis , Korner Antje , Kiess Wieland , Stumvoll Michael , Dietrich Arne , Blueher Matthias , Kloting Nora , Soder Olle , Svechnikov Konstantin

Background: Insulin-like factor 5 (INSL5), a member of the insulin superfamily, is expressed in the colorectum and hypothalamus. INSL5 levels are elevated by prolonged calorie restriction and declined with feeding, suggesting that it might be an orexigenic hormone.Objectives and hypotheses: Our aim was to explore the relationship between INSL5 and different metabolic parameters in lean and obese subjects and to identify possible links between INSL5 and t...
