Resumen
Pregunta de estudio: ¿Se modifica el patrón de hormonas sexuales y la calidad seminal en varones jóvenes obesos mórbidos sometidos a cirugía Bariátrica? Respuesta resumida: junto con la pérdida brusca de peso tras la cirugía Bariátrica se observa una mejora en el patrón de hormonas sexuales con algún deterioro en la calidad seminal. Lo que ya se sabe: Existe una estrecha relación entre la obesidad y la infertilidad masculina. Diseño: Estudio prospectivo longitudinal analítico desarrollado en 18 meses. Materiales y Métodos: Se incluyeron varones jóvenes (n=9) con obesidad mórbida (IMC>≥ 40 Kg/m2), evaluados antes y 6-10 meses después de la cirugía Bariátrica. El estudio seminal se realizó de acuerdo a normas OMS (2010) utilizando un sistema computarizado de análisis del movimiento. Se incluyó el índice de teratozoospermia, el estado de fragmentación del ADN y la inmadurez nuclear. Se determinó el perfil FSH, LH, Testosterona total y libre y SHBG por ECLIA. Todos los pacientes firmaron consentimiento. Resultados: : La pérdida brusca de peso tras la cirugía Bariátrica, se asoció con aumento en la FSH y SHBG y una disminución en la calidad seminal reflejada en la disminución del volumen seminal, el recuento total de espermatozoides, la velocidad curvilínea y la amplitud lateral de la cabeza. La variación del IMC correlacionó positivamente con la del volumen seminal y la SHBG. El perfil glucolipídico mostró una disminución en la insulino-resistencia señalada por HOMA- IR y en los valores de colesterol No- HDL. Limitaciones del estudio: Dado que los pacientes fueron reclutados a partir del Servicio de Cirugía Bariátrica y Metabólica, y por no presentar problemas reproductivos carecen de evaluación uro / andrológica previa. Implicancias de los hallazgos: Los resultados sugieren recomendar consejería reproductiva a fin de alertar a los jóvenes obesos sobre posibles riesgos de disminución del potencial fértil a corto plazo tras la cirugía Bariátrica. Se requieren más estudios que contemplen posibles deficiencias nutricionales post-quirúrgicas y un período de evaluación mayor (12-24 meses) para confirmar los efectos observados y su reversibilidad.
