Prevalence of Hypogonadism in Prepubertal Boys with Cryptrochdism

Grinspon Romina P , Bedecarras Patricia , Gottlieb Silvia , Rey Rodolfo A

Introduction: Cryptorchidism has usually been managed using a surgical approach, with little attention to the underlying pathophysiology.Objectives: To assess gonadal function before treatment in prepubertal boys with cryptorchidism.Methods: In a cross-sectional study we reviewed all clinical charts of patients encoded with the diagnosis of cryptorchidism in the database of a paediatric tertiary hospital, between 2000 and 2017. Inc...

Sertoli Cell Function During Chemotherapy in Pediatric Patients with Acute Lymphoblastic Leukemia

Grinspon Romina P. , Arozarena de Gamboa Maria , Prada Silvina , Gutierrez Marcela E. , Bedecarras Patricia , Aversa Luis , Rey Rodolfo A.

Background: Most reports on gonadotoxicity associated with chemotherapy of acute lymphoblastic leukemia (ALL) comes from studies in adults, and they are mainly focused on the sensitivity of testicular germ cells. Little attention has been placed on Sertoli cells in prepubertal patients, even though Sertoli cell function is essential for adult spermatogenesis.Objective: To evaluate Sertoli cell function in prepubertal boys who receive chemotherapy for ALL...

46, XX Ovotesticular DSD in the Absence of SRY Gene Associated to SOX3 Duplication

Grinspon Romina P , Nevado Julian , Alvarez Maria de los Angeles Mori , Rey Rodolfo A , del Rey Graciela , Chiesa Ana

Background: Ovotesticular DSD is a rare disorder defined by the presence of both ovarian and testicular tissues in the same individual. SRY is present in approximately 1/3 of patients with 46, XX ovotesticular DSD. In SRY-negative ovotesticular DSD, the mechanism responsible for the presence of testicular tissue is not yet understood.Case presentation: A male patient was referred to us for hypospadias and bilateral cryptorchidism at 2.5...

Introduction: Improvements in the treatment of acute lymphoblastic leukaemia (ALL) and non-Hodgkin lymphoma (NHL) have increased survival, with the consequent concern about the long-term effects that childhood chemotherapy may have on ovarian function. AMH constitutes an indirect, reliable biomarker of the ovarian reserve, useful for the assessment of cancer therapy-related ovarian damage.Aim: To evaluate small ovarian f...

Introduction: Gonadotoxicity associated with chemotherapy of hematologic malignancies has been described mainly in adults, focused on the sensitivity of germ cells. Little attention has been placed on Sertoli cells during childhood and puberty, even though Sertoli cell development is essential for adult spermatogenesis.Objective: To assess function of the pituitary-testicular axis, with emphasis on Sertoli cell function,...
