Objectives: We designed a longitudinal study to investigate the association between central pubertal activation with age at the appearance of clinical signs of puberty. We, therefore, assessed nocturnal gonadotropin secretion which can be detected in the form of total luteinizing hormone (LH) immunoreactivity in the daytime- and sleeptime-excreted urine.Methods: Thirty healthy volunteers (17 boys and 13 girls, aged 3.4&n...

Objectives: We aim ed to validate first-morning-voided (FMV) total urinary luteinizing hormone immunoreactivity (U-LH-ir) as a marker for the onset of biochemical puberty and as a noninvasive method to predict the imminent onset of clinical puberty.Methods: We analyzed 651 children (305 boys aged 2.8–17.8 years and 346 girls aged 2.6–18.0 years, both spanning Tanner stages 1-5) across two distinct cohorts. In...

Background: Linear growth during spontaneous puberty contributes approximately 20% to adult height in healthy subjects. The impact of gender-affirming hormone therapy (GAHT) on final height in transgender adolescents is sparsely studied.Aim: We aimed to investigate the growth and final height of Danish transgender adolescents.Methods: Our national cohort of transgender adolescents ...

Background: Transgender adolescents may be treated with gender affirming hormone therapy (GAHT) consisting of gonadotropin-releasing hormone agonists (GnRHa) and cross-sex hormones. Limited data are available regarding the metabolic effects of GAHT in adolescence.Objective: To evaluate the lipid profiles and HbA1c in transgender adolescents after one year of cross-hormone treatment.Patients...
