Background: Gender dysphoria is characterised by an incongruency between the perceived gender identity and the biological sex. The cause of gender dysphoria is unclear and environmental as well as genetic factors may be important. It is well known that during sexual differentiation sex steroids control not only the differentiation of the internal and external genitalia but also the sexual differentiation of the brain. Structural as well as functional differences have been show...

Introduction: Rate of weight gain during early childhood may have an effect on timing of puberty in girls. Biological mechanisms underlying this condition are not fully understood. Studies examining this association in boys report contradictory results. Our aim was to examine the effects of growth rate during the first years of life on the onset of puberty both in girls and boys.Description of methods: 159 children aged between 6 and 9 years who were att...

Background: Hypogonadotrophic hypogonadism (HH) is a complex developmental disorder characterized by a reduction in gonadotrophins (LH, FSH) released from the anterior pituitary. LH and FSH stimulate the ovaries or testes to release sex hormones that cause the onset of puberty, therefore delay in onset or complete absence of puberty is seen in the phenotype, often accompanied by short stature and genital abnormalities. When anosmia accompanies HH in the phenotype it is termed ...

Background: Pubertal gynaecomastia (PG) is considered a clinical sign of an oestrogen–androgen imbalance at the breast tissue level although little evidence exists. PG occurs in 40–60% of adolescent Caucasian boys, and in most cases however, no underlying endocrinopathy can be identified. Very few longitudinal studies on PG exist.Objective and method: As a part of the longitudinal COPENHAGEN Puberty Study we followed 110 healthy Danish boys (ag...

Introduction: There are few published large-cohort studies examining the long-term impact of GNRH analogue treatment for precocious puberty (PP) on fertility in women. The PREFER study analysed fertility in a large cohort of women treated during childhood for PP with triptorelin.Methods: PREFER was a longitudinal, descriptive, non-comparative, epidemiological study conducted in 23 centres in France between February 2007 and November 2009. Women aged &#88...

Background: Little is known about the burden of disease, as evaluated by health related quality of life (HRQoL), in patients with congenital hypogonadotropic hypogonadism (CHH). We characterized the (HRQoL) in a relatively large and well-characterized population of patients with CHH using the 15D, a comprehensive preference-based generic instrument in sampling dimensions for the construct of HRQoL. 15D covers most of the ‘domains of health’ emphasized in the WHO Inte...
