The risk of suffering from gonadal germ cell tumors (GCT) is increased in some patients with different sexual development (DSD), mainly in those with Y chromosome material. This risk, however, varies considerably depending on a multitude of factors that make the decision for prophylactic gonadectomy extremely difficult. In order to make informed recommendations on the convenience of this procedure in cases where there is potential for malignancy, this consensus guide evaluates the latest clinical evidence, which is generally low, and updates the existing knowledge in this field., (Copyright © 2022 SEEN and SED.

Some people, including minors, have a gender identity that does not correspond to the sex assigned at birth. They are known as trans* people, which is an umbrella term that encompasses transgender, transsexual, and other identities not conforming to the assigned gender. Healthcare units for trans* minors require multidisciplinary working, undertaken by personnel expert in gender identity, enabling, when requested, interventions for the minor and their social-familial environment, in an individualized and flexible way during the gender affirmation path. This service model also includes hormonal treatments tailored as much as possible to the individual's needs, beyond the dichotomic goals of a traditional binary model. This guide addresses the general aspects of professional care of trans* minors and presents the current evidence-based protocol of hormonal treatments for trans* and non-binary adolescents. In addition, it details key aspects related to expected body changes and their possible side effects, as well as prior counselling about fertility preservation., (Copyright © 2022 Asociación Española de Pediatría.
