ABSTRACT
In this study, we aim to examine effects of an experimentally induced unilateral varicose ovarian vein on the activities of anti-oxidant enzymes in an adult rat ovary. In this experimental study, a total of 30 adult female Wistar albino rats were divided into three groups. 10 rats in group 1 as the varicocele group, 10 rats in group 2 as the control group and 10 rats in group 3 as the sham group, that underwent a sham operation and. Anti-oxidant assays were assessed via specific assay kits. Statistical analysis was performed using the one way ANOVA and Tukey's tests were used for post hoc multiple comparisons, P<0.05 was considered statistically significant. The effects of the unilateral varicosity was more evident on the left side when compared to the right side as all activities of the anti-oxidant assayed were significantly reduced, P 0.05 when compared to the right side. Also, in this present study, the effect of the unilateral varicose vein was bilateral as there were no significant differences recorded between the two sides. Finally the result of this study shows that varicocele may lead to female infertility through various factors that includes reduction in the activities of anti-oxidant enzymes.
En este estudio, nuestro objetivo fue examinar los efectos de la inducción experimental unilateral de una vena ovárica varicosa en la actividad de enzimas antioxidantes en un ovario de rata adulta. Un total de 30 ratas albinas Wistar, hembras adultas, se dividieron en tres grupos. Diez ratas en el grupo 1 (grupo varicocele), diez ratas en el grupo 2 (grupo de control) y diez ratas en el grupo 3 (grupo de tratamiento simulado), que se sometió a una operación simulada. Ensayos con anti-oxidantes se evaluaron a través de kits de ensayo específicos. El análisis estadístico se realizó mediante ANOVA de una vía y las pruebas de Tukey fueron utilizadas para comparaciones múltiples Post Hoc, siendo el P<0,05 considerado como estadísticamente significativo. Los efectos de la varicosidad unilateral fue más evidente en el lado izquierdo cuando fue comparada con el lado derecho en todas las actividades del ensayo con anti-oxidante que se redujeron significativamente, el P 0,05 cuando se compara con el lado derecho. Asimismo, en el presente estudio, el efecto de la vena varicosa unilateral fue bilateral ya que no hubo diferencias significativas registradas entre las dos partes. Por último, el resultado de este estudio muestra que el varicocele puede conducir a la infertilidad femenina a través de diversos factores que incluye la reducción en la actividad de las enzimas antioxidantes.

OBJECTIVES: Several researchers have reported the relationship between infertility in male and varicocele for so many years but the implication of varicocele in female patients is remains elusive. Here, we aim to examine the effects of unilateral varicose ovarian vein on antioxidant capacity and oocyte quality of rat ovary after the experimental creation of varicocele in female rats. MATERIALS AND METHODS: In this study, thirty adult female albino rats were divided into three equal groups: Group 1 as the control group has 10 rats, Group 2 as the sham group has 10 rats and they underwent a sham operation and finally Group 3 has the varicocele group has 10 rats. Antioxidant assays for superoxide dismutase, glutathione peroxidase and catalase were performed using specific assay kits and gene expression for Bax, Bmp-15, Hsp-27 and Gdf-9 was done via real time PCR. RESULTS: The adverse effects of the experimentally induced varicocele were reported and recorded on the left ovary compared to the right sided ovary (no varicocele induction) in the varicocele group. Real time PCR data shows that the expression of Gdf-9, Hsp-27 and Bmp-15 genes were all significantly reduced at p≤ 0.05. CONCLUSION: The results of this study show that reduced gene expression of Bmp-15, Gdf-9 and Hsp-27, increased gene expression of bax and an imbalance between pro-oxidant/antioxidant ratio are few of the several mechanisms by which varicocele may lead to infertility in female.
