  The genotoxicity study of cyproterone acetate was carried out in mouse bone marrow cells using Sister Chromatid Exchanges (SCEs) and Chromosomal Aberrations (CAs) as a parameter. The effect of cyproterone acetate was studied at 6.25, 12.50 and 25.00 mg kg-1 of body weight and was found to be genotoxic at 12.50 and 25.00 mg kg-1 of body weight. Further the effect of vitamin C on 25.00 mg kg-1 of body weight of cyproterone acetate was also studied. Three doses of vitamin C i.e. 20, 40 and 60 mg kg-1 of body weight were given along with 25.00 mg kg-1 of body weight of cyproterone acetate. Treatments along with vitamin C results in a significant decrease in CAs and SCEs suggesting an antigenotoxic role of vitamin C against cyproterone acetate induced genotoxic damage in mice bone marrow cells.

  Reproductive fitness is best studied by taking together a number of parameters like the mean number of offspring produced and the sex-ratio. The Muslims of Aligarh city are predominantly Sunnis, though a considerable number of Shias are also there. Among the Sunnis approximately one fourth of the population constitute Syed, Sheikh, Moghal and Pathan, while three fourth belong to various lower Biradaris. In the present study we have reported incidence of marriage, fertility and secondary sex ratio among women of high rank (Ashraf) castes and low rank (Ajlaf) castes of Muslims in the northern region. Ashraf comprises Sheikh, Syed and Pathan, whereas Ajlafs belong to Qureshi, Saifi and Ansari biradaris. Maternal age was scored as above 45 and below 45 years of age. Significant effects of maternal age were seen on sterility, fertility and secondary-sex ratio of the offspring, whereas populations did not show consistent differences except those between Ashraf and Ajlaf taken together.
