Resumen

La terapia con testosterona está indicada para el tratamiento de afecciones patológicas relacionadas con la edad. Todavía existen algunas dudas sobre la seguridad de la terapia, debido a una susceptibilidad a las enfermedades prostáticas. Los análisis histopatológicos se basan en metodologías subjetivas, y es importante validar métodos cuantitativos, como el análisis fractal, que detecta cambios morfológicos sutiles y transforma la complejidad de la forma en datos analíticos cuantitativos. Por lo tanto, el estudio investigó los efectos de la terapia con testosterona en la remodelación del microambiente prostático y la validación del método fractal. Ratas Wistar de 150 días de edad se dividieron en dos grupos experimentales (n = 5): Grupo T: recibieron inyecciones subcutáneas de cipionato de testosterona (5 mg/kg de peso corporal) diluido en aceite de maíz en días alternos durante 4 semanas; Grupo C: recibió inyecciones subcutáneas de aceite de maíz como vehículo. Los animales fueron sacrificados a los 180 días de edad. Después de la eutanasia, se recolectó la próstata ventral de los animales, se diseccionó y se realizó el procesamiento histológico para el análisis fractal, estereológico y de altura epitelial. Hubo una reducción de la dimensión fractal en el grupo T, acompañada de un aumento de la altura epitelial. El análisis estereológico reveló una disminución del compartimento estromal y un aumento del compartimento epitelial. Así, los resultados demuestran que el análisis fractal fue efectivo en la evaluación de alteraciones relacionadas con la suplementación hormonal, evidenciando las alteraciones morfológicas prostáticas observadas por los otros métodos.
