Background: The majority of Turner syndrome (TS) girls need exogenous estrogen treatment to induce normal uterine growth. The optimal estrogen treatment protocol has not been determined.Objective and hypotheses: To compare the effect of two different dosing regimens of oral 17β-estradiol on uterine size with the hypotheses that most girls with TS would benefit from a higher dose.Method: A double-blind 5-year randomized control...

Background: Reduced bone mineral density (BMD) is seen in Turner syndrome (TS) with an increased risk of fractures and osteoporosis. Body composition in TS is characterised by increased body fat (FM) and decreased lean body mass (LBM), even with a normal BMI. Oestrogen replacement therapy for attaining and preserving normal bone mass is necessary in most TS girls. There is a potential role of age-specific estrogen doses, with lower doses used in the early puberty and higher do...

Background: Sex hormones organize brain structure and function, particularly early in life. Endocrine neuroimaging offers the opportunity to assess the impact of sex hormones but also genetic contributions on structural neuroanatomy and neurocognitive-affective function in disorders of sexual development (DSD). This may be particularly relevant from a psychopathological perspective of how such neural changes contribute to mood and anxiety disorders frequently observed in DSD.<...

Magnetic resonance imaging (MRI) of the brain in disorders of sexual development (DSD) is still relatively scarce despite the opportunities it offers for understanding the influence of sex hormones on emotion and cognition. In this talk I will give an update on current structural and functional MRI research in different DSDs such as Klinefelter syndrome, Turner syndrome, Congenital Adrenal Hyperplasia, or Familial Male Precocious Puberty. Finally, parallels will be drawn to cu...

Background and Aim: Several genetic variants associating with hepatic fat content in adults have been identified in genome-wide association studies. Their effects in children remain unclear. This study aimed to test the effect of genetic variants known to associate with hepatic fat in adults, individually and combined as a genetic risk score (GRS), on cardiometabolic traits, and to investigate the predictive ability of the GRS for hepatic steatosis in children...

Background: Spatial navigation is an essential human skill that helps individuals track their changes in position and orientation by integrating self-motion cues. Meta-analyses indicate that males, on average, perform better than females on a number of spatial tasks. Sex steroids, mainly androgens, modulate the remodeling of synapses in the prefrontal cortex and hippocampus, a limbic brain area with critical influence on spatial and contextual memory. Androgen...

Background: Metformin is increasingly used in pregnancy and passes the placenta. Data on long-term effect on the offspring is essentially lacking. We explored possible effects of intrauterine metformin exposure on metabolic health, in 8-years-old children of women with PCOS.Methods: Follow-up of children from the PregMet-study - an RCT comparing metformin (2000 mg) to placebo during PCOS pregnancies. The primary endpoint was Body Mass Index (BMI). Second...

Background: Final height in patients with congenital adrenal hyperplasia (CAH) is generally assumed to be lower than the population norm. Besides CAH subtype and age at diagnosis, timing of pubertal development is considered to have a significant impact on final height. In most CAH patients, puberty starts within normal ranges, although at a somewhat earlier mean age compared to reference populations. CAH-complicating gonadotropin-dependent precocious puberty has been reported...
