RESUMO
PURPOSE: Male sexual desire and erection are directly or indirectly affected by hormone and neuroendocrine response. We investigate the changes of the serum dopamine and testosterone level by visual erotic stimulation-induced sexual excitement. MATERIALS AND METHODS: The age of volunteers was ranged from 25 to 65 years, with an average of 45.5years. Serum were collected at rest and after visual erotic stimulation. Sexual excitement induced by erotic film for 30 minutes and erectile status was monitored by Rigiscan. The response of visual erotic stimulation were divided into three groups according to degree of sexual excitement. i.e. no response (Group I), mild excitement(Group II), excitement (Group III). RESULTS: Although some changes were observed in serum dopamine and testosterone level of all 32 patients after visual erotic stimulation, it did not showed statistically signigicant change (p=0.450, p=0.058). According to excitement response, group I and II were not showed statistically significant change in both dopamine and testosterone. Only dopamine of the group III was showed statistically change (dopamine: p=0.041, testosteron: p=0.257) CONCLUSIONS: In this study, serum testosterone level is not showed significant change irrespective of the degree of sexual excitement induced by visual erotic stimulation. However, serum dopamine was changed with statistically significance only in sexual excitement group.
