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.

The data are compared to those of male-to-female transsexual persons.Design: Cross sectional study.Methods: Female-to-male transsexual persons, post SRS, (n=48...

However, few studies have evaluated the impact of collection devices on steroid hormone analysis; and none with the currently used methods.Objective: The aim of this pilot study was to minimize pre-analytical errors based on sample collection methods.Meth...
