Pre-pubertal cyclophosphamide exposure-induced mutilation in spermatogenesis, steroidogenesis and testicular architecture in SD rat: Protection from an alternative herbal viagra.

INTRODUCTION

The children and adolescents with cancer who are getting remission and becoming long-term survivals are at high risk of impaired fertility. Cyclophosphamide (CP), the most frequently used drug for childhood-cancers causes various types of reproductive toxicity. We aimed at evaluating protective role of chlorophytum borivillianum (CB) extract against pre-pubertal CP exposure-induced testicular toxicity in rats.

MATERIALS AND

METHODS

Sixty male pre-pubertal SD rats aged postnatal day (PND) 24 were divided into 5 groups. Group-I (control), group-II (CP), and group-III (CB) received normal saline (NS), CP15mg/kg/day and CB200mg/kg/day respectively during PND29-42; group-IV and group-V received CB100mg/kg/day and CB200mg/kg/day respectively along with CP15mg/kg/day for the same period. Half of the rats from each group were sacrificed on PND43 (puberty) to evaluate alterations in oxidative stress parameters and histopathology. Remaining rats were sacrificed on PND63 (young adult age) and sperm analysis (density, motility, viability, and morphology), hormonal (Testosterone, Luteinizing hormone, Follicle stimulating hormone) estimation and histomorphometrical evaluation was done. Co-administration of CB have shown a dose-dependent and significant improvement in anomalies caused by CP as compared to rats received CP only.

RESULTS

CP treatment led to significant decrease in body weight gain, organ weights, oxidative defense mechanisms, hormone levels, steroidogenesis, spermatogenesis, sperm parameters and increase in oxidative stress, percentage of sperm abnormal morphology as compared to control rats. CP-treated rats have shown severe damage in testicular architecture and development as compared to control rats as evidenced by histopathology and morphometric analysis.

CONCLUSION

Co-administration of CB extract significantly reversed the footprints of these effects in dose-dependent manner. These protective effects of CB may be exploited in improving gonadal function in childhood cancer long-term survivals.
