Abstract

In this study, we aimed to compare changes in cavernosal tissues in rats with antiandrogen treatment and orchiectomy. A total of 42 Wistar albino rats were divided into four groups. Group I, control group, Group II, LH-RH was given for 1 month, Group III-LH-RH + Bicalutamide was given for 1 month, and Group IV was defined as orchiectomy and followed up for 1 month. Measurements of intracavernosal pressure with different electrical stimuli and pathological findings of smooth muscle collagen in cavernosal tissues were examined. While the cavernosal pressure response in all the different electrical stimuli given in the control group and in all other groups was significantly lower than that in the other groups, it was statistically significant at 7.5 and 10 V (p = .005, p < 0001). According to the pathologic evaluation, the density of tissue collagen increased significantly in the other groups according to the control group. In groups 3 and 4, the density of 4+ collagen was found to be increased according to Groups 1 and 2. In the LH-RH alone group, it appears that there are no 4+ colloid density and less damage. According to these findings, the negative effect of LH-RH treatment on cavernosal tissues appears to be less.

Keywords: castration; cavernosal tissue; erection; intracavernosal pressure.
