Objective: We aimed to investigate the effects of a Carbohydrate-rich diet on vas deferens contractility and histology.

Materials and Methods: Twenty mature male rats were subjected into two groups. The control group received regular food and water and the study group received regular food and a carbohydrate-rich liquid diet mixture of 37–40% fructose, 30–36% sucrose and 27–30% glucose instead of water and prepared stock diet was diluted with 50% water. Animals were weighted and sacrificed after six weeks and the vas deferens has been evaluated with in vitro studies. Five rats from both the control and study groups, were separated into subgroups for dapoxetine administration 4 hours before they were sacrificed.

Results: At the beginning of this study, the mean body weights were 228.6±6.7 g (range: 205-237) and 231.4±9.6 g (range: 202-243) in control and study groups, respectively. The mean body weights were 247.1±4.8 g (236-252) in the control group and 318.8±9.3 g (314-326) in the study group (p<0.001). Weight gain was more distinct in the study group when compared to control group (p<0.001) (9% vs 27.4%). Contractile responses were recorded in each group, including the dapoxetine subgroups, to various noradrenaline concentrations; all groups had similar results (p>0.05). Responses to Adenosine Three Phosphate (ATP) were also not significant (p>0.05). The contractile responses at the same frequencies of electrical field stimulation (EFS) were similar in both groups (p>0.05). Histological examinations showed no abnormalities in either group.

Conclusion: Carbohydrate-rich diet caused no increase in fibrotic activity, and pharmacological and histological properties remained stable, but caused significant weight gain over a short time period. Furthermore, dapoxetine had no effect on the contractility of the vas deferens.
