Brief Summary: This study analyzed ovariectomy samples from 52 transmasculine individuals who had been using testosterone for >1 year (median 32, IQR 27–39 months) with serum concentrations in the male reference range. In one third (16/52) of the cohort, histological signs of recent ovulatory activity were observed, including the presence of ovulatory follicles, corpus luteum and corpus albicans. This was similar in the subgroup of 15 individuals who had previously us...

Brief summary: Over the recent years several publications reported on next generation sequencing (NGS) in cohorts of patients with congenital hypothyroidism (1). Based on these data, diagnostic yield was higher in patients with gland-in-situ, than with thyroid dysgenesis. Further studies performed NGS only in cohorts of patients with gland-in-situ, excluding thyroid dysgenesis forms such as athyreosis, ectopy, or hypoplasia (2). The publication of Levaillant ...
