Afectación de la función testicular en niños con criptorquidia

Abstract

Poca atención se ha puesto en la capacidad funcional del testículo en los niños con criptorquidia. La Hormona Anti-Mülleriana (AMH) producida por la célula de Sertoli es el marcador ideal para evaluar la función testicular durante la infancia. Objetivo: Evaluar la función testicular en niños prepuberales antes de la orquidopexia. Buscar asociación entre función testicular y las características de la criptorquidia.Materiales y métodos: Estudio retrospectivo, de corte transversal y analítico. Medida de resultado principal: concentración de AMH. Medidas de resultados secundarias: concentración de gonadotrofinas y testosterona. Para comparación, se utilizaron los niveles hormonales de 179 niños normales.Resultados: Se seleccionaron 186 pacientes con criptorquidia bilateral y 124 con criptorquidia unilateral. La mediana de AMH fue menor a 0 en ambos grupos. La concentración sérica de AMH fue menor en pacientes con criptorquidia bilateral comparados con niños controles y con criptorquidia unilateral entre 6 meses y 8.9 años. La concentracion de AMH estuvo por debajo del rango normal en 16,6% del total de pacientes con criptorquidia y gónadas presentes (22,6% criptorquidia bilateral y 8,1% criptorquidia unilateral).Conclusión: Los niños prepuberales con criptorquidia, especialmente aquellos con criptorquidia bilateral, tienen menor producción de AMH y una considerable prevalencia de disfunción testicular.

Introduction: Little information is available on testicular function in boys with cryptorchidism. Anti-müllerian hormone (AMH) is a good marker of testicular function in childhood. Objective: the aim of this study was to assess testicular function in boys with cryptorchidism before orchiopexy, and to look for an association between testicular function and features of cryptorchidism. Patients and methods: We performed a cross-sectional, retrospective study. Main outcome measure was serum AMH concentration, and secondary variables were gonadotropin and testosterone concentrations. For comparison, levels in 179 normal boys were compared. Results: 186 boys with bilateral cryptorchidism and 124 with unilateral cryptorchidism were included. Mean SDS AMH was below 0 in both groups. Mean serum AMH was lower in boys with bilateral cryptorchidism, as compared to unilateral cryptorchidism and controls between 6 months and 8.9 years of age. Testosterone was lower than normal in boys < 6 months of age. Gonadotropins were rarely affected. Conclusions: Prepubertal boys with cryptorchidism, especially those with bilateral forms, have a lower AMH production, reflecting testicular dysfunction.
