Abstract

Environmental pollutants such as di-(2-ethylhexyl) phthalate (DEHP) adversely affect reproductive system tissue differentiation and functions with exposure at intrauterine, neonatal or adult stages of life, thereby potentiating male infertility later in life. World health organization estimates a global infertility prevalent rate of 10-15%, and 20-30% among Nigerians, with male factor constituting about 40-50% of infertility cases. This study was designed to investigate the effect(s) of oral vitamins C and E on DEHP induced changes in some semen parameters and serum testosterone concentration in adult Wistar rats. Seventy (70) adult male Wistar rats weighing between 156-250 g were randomised into 7 experimental groups 1, 2, 3, 4, 5, 6 and 7 (group n=10). Animals in groups 1, 2 and 3 were treated with 0.02 mg, 20 mg, 200 mg oral DEHP/kg bw daily respectively, while those in groups 4, 5 and 6, in addition to the above DEHP treatments, were treated with 100 mg ascorbic acid and 67.5 mg α-tocopherol per kg bw daily respectively. Rats in group 7 served as Control and were treated with vehicle. All treatments lasted for 60 days. After, over night fasting, samples of semen and serum were obtained for analysis. Results obtained were expressed as mean ± standard deviation and analyzed for significant differences in means using one way ANOVA and Post Hoc test. Relative to the control reference values, groups exposed to oral DEHP had significant (p
