Introduction: Gonadectomy may be indicated in people with differences or disorders of sex development (DSD). Based on historical data from the International-DSD (I-DSD) Registry that showed considerable practice variation, this I-DSD care quality improvement project seeks to determine, through prospective surveillance, the frequency of gonadectomy in individuals with DSD internationally.Methods: All existing I-DSD centre...

Background: Lipodystrophy syndromes comprise a large group of extremely rare diseases characterized by loss or dysfunction of adipose tissue. Due to their extreme rarity and variability, research in the field of lipodystrophy is difficult for single centres warranting larger co-operations.Methods: Therefore, the European Consortium of Lipodystrophies decided to found an international registry in 2016. This registry is ba...

Introduction: Depending on the underlying diagnosis, Disorders of Sex Development (DSD) can be associated with an increased risk of germ cell cancers. To date, however, knowledge regarding the indications and timing of gonadectomy is lacking.Methods: The International-DSD (I-DSD) Registry was interrogated for anonymised information regarding the diagnosis, karyotype, sex of rearing and timing of gonadectomy, if undertaken, of all individuals of any karyo...

Introduction: The term lipodystrophy describes a rare disease subdivided into a heterogenous group of even rarer subforms. The rarity of this disease makes research in this area extremely difficult and international co-operation is mandatory to accumulate data sets of sufficient size. The European Consortium of Lipodystrophy (ECLip) consisting of an association of European experts in the field of lipodystrophy has therefore decided to set up a registry for patients with lipody...

Background: Turner syndrome (TS) is one of the most common genetic disorders in females and occurs in phenotypic females who are missing all or part of one sex chromosome. While the most common mosaic forms of the disorder are 45,X/46,XX and 45,X/46,Xiq, mosaicism for cells containing Y chromosome material is well documented.Objective and hypotheses: Owing to increased risk of gonadoblastoma (GB), current recommendations are for elective gonadectomy foll...

Endocrine and reproductive sequelae are among the most commonly reported complications in survivors of childhood cancer and brain tumors with nearly 50% individuals affected. Treatment related hormonal disorders may occur in a delayed fashion as late effects, several years to decades after the completion of cancer or tumor therapy, especially when resulting from the irradiation of the endocrine glands. This phenomenon requires a systematic, risk-based, approach in the screenin...

Background: The anogenital distance (AGD) is considered a valid marker of altered androgen action in utero. Recently, reduced AGD has been shown in males with hypospadias, cryptorchidism, reduced semen quality and infertility. It has also been proposed as a new marker to be used by clinicians when managing patients with Disorders of Sex Development. However, little normative data exist and measurement methods vary.Objective and hypotheses: We established...

Background: CHI is a rare condition which can be related to neurological damage due to hypoglycaemic brain injury. Long hospital admissions maybe necessary which can impact babies’ experience of posture and movement, translating to a motor delay. A physiotherapy developmental assessment is a vital part of a multidisciplinary team approach to personalising care. Assessment during admission is essential to provide appropriate developmental support, particu...

Introduction: Boys born small for gestational age (SGA) often have undermasculinized genitalia. Little is known about the pubertal development and gonadal function on a longer-term in this specific group of males.Aims: To determine the (pubertal) development and long-term urological and endocrine outcome of undermasculinized boys born SGA compared to undervirilized boys born appropriate for gestational age (AGA).<p c...

Background: Gonadectomy is generally postponed until early adulthood in complete androgen insensitivity syndrome (CAIS) and close surveillance of gonads in situ proposed in males with partial AIS (PAIS). Delaying gonadectomy further is controversial given the lack of data regarding germ cell cancer (GCC) development in adulthood and the absence of biomarkers for noninvasive GCC screening.Aims and objectives: To study the prevalence of invasive G...
