Therefore, we investigated the relationship between indices of thyroid status and body composition in a population of euthyroid men.Methods: Healthy male siblings (n=677, 25–45 years, mean BMI 25.2) were recruited in a cross-sectional, population-based st...

The majority are cortisol excreting carcinomas, followed by aldosterone or androgen excess.(2) Estrogen secreting ACC are extremely rare.

Introduction: We describe a monozygotic twin pair, of which one boy was diagnosed with anorchia. Both were followed-up till age 17.Case report: At birth, in one twin 46 XY boy (A), testes were not palpable while his brother (B) was unaffected. Stimulation with human chorionic gonadotrophin (hCG) and orchidopexia were unsuccessful at age 3. A second hCG-stimulation test was performed at age 8, where serum testosterone response failed to increase. No testi...
