Effect of some chemotherapy drugs) vincristine and vinblastine) on females albino mice fertility and sex hormones level

Abstract

The aim of this study was to determine the effect of chemotherapy (vincristine and vinblastine) on the fertility and sex hormones level of female mice. Twenty four female albino mice were divided into three equal groups. The First group injected with vincristine 0.05 mg/kg intraperitoneally daily for 3 weeks. The second group injected with vinblastine 0.05 mg/kg intraperitoneally daily for 3 weeks. The third group treated with normal saline intraperitoneally daily for 3 weeks as control group. Blood samples were collected by using heart puncture within plastic syringes and transferred to plastic tubes. Blood centrifuged and serum was harvested for hormonal assay. The animals in each group were killed by dislocation of cervical vertebrate in third week of the treatment. Ovaries weighed and fixed with Bouin solution for histological study. Results showed significantly (P<0.05) decreased in ovaries weight on groups treated with vincristine and vinblastine as compared with control group. The mean numbers and diameters of primary, secondary follicles and corpus luteium, and hormones level [follicular stimulating hormone (FSH), lutenizing hormone (LH), estrogen and progesterone] were significant declined in groups treated with vincristine and vinblastine as compared with control group. Results indicated that fertility and sex hormones level reduced in females treated with chemotherapy drugs vincristine and vinblastine
