ABSTRACT
Varicoceles are abnormal tortuosity and dilatation of the veins of the pampiniform plexus that drain the testis. The pathophysiology of testicular damage in varicocele has not been completely understood. However there is an increasing body of evidence pointing towards the role of reactive oxygen species and oxidative stress in the pathogenesis of varicocele related subfertility. In the present study we examined the role of proanthocynidin-rich ethanol extract of grapefruit seed as an antioxidant in protecting the testis against damage in experimental varicocele. Three groups of rats were constructed as the first group had intact rats; experimental bilateral varicoceles were established by complete ligation of the left and right main spermatic veins in the later two groups. The third group had in addition daily gavage administration of 1 Omg/ kg body weight ethanol extract of grapefruit seed. Eight weeks after varicocele induction, bilateral testicular weights, bilateral testicular volumes, bilateral caudal epididymal sperm characteristics, and bilateral testicular histology and serum hormone levels were tested. It was found that the testes of grapefruit seed extract treated animals had better functional and histological profiles compared to the untreated varicocelized animals. These results indicated the effectiveness of grapefruit seed extract for preservation of testes function morphology in varicocelized subjects.
RESUMEN
Los varicoceles son tortuosidades anormales y dilataciones de las venas del plexo pampiniforme que drenan el testículo. La fisiopatología del daño testicular en el varicocele no se ha entendido completamente. Sin embargo, existe un creciente cúmulo de evidencias que apunta hacia el papel de especies reactivas al oxígeno y al estrés oxidativo, en la patogénesis del varicocele relacionados con subfertilidad. En el presente estudio, se examinó el papel de proantocianidina en el extracto etanólico de semilla del pomelo, como un antioxidante en la protección contra el daño testicular experimental en el varicocele. Tres grupos de ratas fueron seleccionados, un grupo de ratas control y dos grupos experimentales. En estos dos últimos grupos, se provocó varicocele bilateral a través de la ligadura completa de las venas testiculares principales izquierda y derecha. El tercer grupo tuvo además una sonda de administración diaria de 10 mg /kg de peso corporal, de extracto etanólico de semilla de pomelo. Ocho semanas después de la inducción de varicocele, se determinó el peso testicular bilateral, volúmenes testiculares bilaterales, características de los espermatozoides de la cola del epidídimo bilateral, la histología testicular bilateral y los niveles séricos de hormona. Se determinó que los testículos de los animales tratados con extracto de semilla de pomelo presentaban una mayor funcionalidad y mejores perfiles histológicos, en comparación con los animales varicocelizados no tratados. Estos resultados indican la eficacia de extracto de semilla de pomelo para la conservación de la morfología funcional testicular, en sujetos varicocelizados.
