ABSTRACT
Oxidative stress is increased in varicose veins. Many studies have implicated oxidative stress in the pathogenesis of infertility causing diseases of the female reproductive tract. The aim of this study was to determine whether varicocele can cause raised levels of reactive oxygen species and denaturation of mitochondrial structure in ovaries of female rats or not. In each experimental study, 15 weaning-age female rats were divided equally in 3 groups Unilateral Varicose Vein (A), Sham (B) and Control (C) groups. Mitochondrial structure and malondialdehyde levels as a product of lipid peroxidation and Prooxidants-Antioxidants Balance were evaluated 60 days after intervention in proestrus stage. Comparisons between groups were made by the measured test. After 2 months, our results showed that mitochondrial structure ultra-structurally was denatured with histologic examination, malondialdehyde and prooxidants-antioxidants balance levels of left ovaries increased significantly in varicocele group compared to control and sham groups (P0.05). In the right side, malondialdehyde increased significantly, but in prooxidants-antioxidants balance levels, there is no significant differences between groups. The data of control and sham groups were the same. These findings may support the concept that increased levels of malondialdehyde and PAB in varicocele may cause negative effects on fertility, so using antioxidants maybe useful.
RESUMEN
El estrés oxidativo aumenta en las venas varicosas. Diversas investigaciones han implicado al estrés oxidativo en la patogénesis de las enfermedades que causan la infertilidad del tracto reproductivo femenino. El objetivo de este estudio fue determinar si el varicocele puede provocar niveles de especies reactivas del oxígeno y la desnaturalización de la estructura mitocondriales en los ovarios de ratas. En cada estudio experimental, cinco ratas hembras en edad de destete se dividieron por igual en 3 grupos Várices unilateral (A), simulado (B) y control (C). La estructura mitocondrial y los niveles de malondialdehído como un producto de la peroxidación lipídica y el balance pro-oxidantes-antioxidantes (BPA) se evaluaron 60 días después de la intervención en la etapa proestro. Las comparaciones entre grupos se realizaron mediante la prueba de medición. Después de 2 meses, observamos que la estructura mitocondrial se desnaturalizó ultraestructuralmente, los niveles malondialdehído y el balance prooxidantes-antioxidantes de los ovarios izquierdos aumentaron significativamente en el grupo A en comparación con los grupos B y C (P0.05). En el lado derecho, los niveles de malondialdehído aumentaron significativamente, pero el BPA, no mostró diferencias significativas entre los grupos. Los datos de los grupos B y C eran los mismos. Estos hallazgos pueden apoyar el concepto de que el aumento de niveles de malondialdehído y BPA en presencia de varicocele, puede causar efectos negativos sobre la fertilidad, por tanto el uso de antioxidantes puede resultar útil.
