Journal of andrology 2012 Sep-OctThe pilot study presented was conducted to determine as to whether ergot alkaloids (alpha-adrenergic blockers) have a potential effect on penile erectile function. The influence of dihydroergotoxine, bromocriptine, and ergotamine was studied on the erection ability in intact, two-grade outbred male Wistar albino rats that were out of their estrous phase. The experimental animals were injected intrapenially with the substances under examination: dihydroergotoxine mesylate (0.1 mg/0.1 mL, 0.3 mg/0.1 mL, and 1 mg/0.1 mL), bromocriptine mesylate (0.3 mg/0.1 mL, 1 mg/0.1 mL, and 3 mg/0.1 mL), and ergotamine tartrate (0.1 mg/0.1 mL, 0.3 mg/0.1 mL, and 1mg/0.1 mL). Every dose was tested on a pattern of 30 rats. These mentioned substances were injected in the amount of 1 mm to the left of the proximal part of the superficial dorsal vein of the penis, in the region of the penis root. After injection, the animals were then observed within the next 90 minutes. In the trial, the following was observed: the number of rats with an erection achieved, the period of time from intrapenial application to the appearance of the first erection, and the duration of the erection. Ultimately, the research results confirm the efficiency of dihydroergotoxine and bromocriptine as erectogenic agents, as well as ergotamine as a detumescent compared with saline solutions.
