Administración neonatal única de aceite de soya y/o tamoxifeno afecta permanentemente a la histomorfología testicular en ratas adultas. Veterinaria México OA. 2016;3(2). doi: 10.21753/vmoa.3.2.364
El objetivo de este estudio fue evaluar el efecto de la administración de tamoxifeno (Tx) y aceite de soya (SO) durante el periodo crítico de la diferen- ciación sexual hipotalámica en ratas macho recién nacidas, en el contexto de la histomorfología gonadal durante la edad adulta. Los animales se dividieron al azar en tres grupos (n = 5 cada uno). Una hora después del nacimiento, un grupo fue tratado por vía subcutánea con 200 μg de Tx y 20 μL de SO comercial como vehículo; mientras otro grupo fue tratado solo con 20 μL de SO, y el grupo control no recibió ningún tratamiento. Todas las ratas se pesaron y sacrificaron por dislocación cervical a los 90 días postratamiento. Se extrajeron los testículos, se pesaron y procesaron para la evaluación his- tológica. La administración única de Tx y de SO durante el periodo crítico de la diferenciación sexual del hipotálamo altera de forma permanente la histomorfología testicular, la espermatogénesis y el peso corporal en la edad adulta. Las alteraciones incluyen: vacuolización, reducción del número de espermatogonias y de células de Sertoli. La administración de Tx redujo el peso testicular, el diámetro y el área de los túbulos seminíferos, así como la altura del epitelio germinal, e incrementó el espacio intertubular. El SO redujo el número de espermatocitos y espermátides, incluso más que el Tx. No se afectó el número de células de Leydig. La posibilidad de que el aceite de soya actúe como disruptor endócrino, amerita más atención y abre la posibi- lidad para el desarrollo de nuevos métodos de control de plagas.
