Background: Undescended testes in patients with defective mini-puberty contain germ cells that fail to differentiate normally into Ad spermatogonia and ultimately leads to infertility. Six months treatment with the gonadotropin-releasing hormone GnRH increases luteinizing hormone and testosterone secretion and rescues fertility in the majority of pathological cryptorchid testes. Several Y chromosomal genes in the male-specific Y region (MSY) are essential for spermatogenesis, ...

PCOS treatment in adolescence should aim at improving ovarian function, based on the pathophysiology of this condition. We previously described in cystic fibrosis and then in the PCOS an increase in HMGB1, secondary to reduced cystic fibrosis transmembrane conductance regulator (CFTR) expression in the ovary, associated with insulin resistance and inflammation that both characterize PCOS. Inositols and ALA derivatives are considered a good therapeutic option for their possible...

The treatment of Polycystic Ovary Syndrome (PCOS) during adolescence is controversial. The aim of the international evidence-based guideline was to promote accurate diagnosis, optimal consistent care, prevention of complications and to improve patient experience and health outcomes. Extensive international health professional and patient engagement informed the priorities and core outcomes for the guideline. Internationally nominated panels including women with PCOS and a mult...

Background: Anogenital distance (AGD) is an indicator of androgen action in utero. Reduced AGD has been found in males with hypospadias, cryptorchidism, low semen quality and infertility. Its usefulness as a clinical marker in patients with Disorders of Sex Development (DSD) is currently being investigated. However, detailed age, sex and method related reference ranges do not exist. Whether individual (body-size-adjusted) AGD is stable postnatally also remains to be e...

Introduction: Treatment of patients with VSD (Variation of Sex Development), in particular severe hypospadias, is associated with high rate of post-operative complications using current surgical procedures. This leads to a high rate of re-operation in an already emotionally complicated situation. We improved the tissue engineered acellular tubular collagen scaffolds that showed promising results in the rabbit model to implant it to a dog model. This FDA approved new version ac...

Purpose: Transgender adolescents are treated with gonadotropin-releasing hormone analogues (GnRHa), followed by the addition of gender-affirming hormones. Since during puberty the body reaches maturation, concerns have been risen that the treatment may have negative outcome later in life. The aim of this study is to determine whether treatment with GnRHa and subsequent addition of hormones results in a more atherogenic profile than peers at the age of 22.<p class="abstext"...
