Twenty-five patients with retrograde ejaculation/loss of emission were
treated with ephedrine sulfate or imipramine hydrochloride. Seventeen
of them suffering from both diabetes and retrograde ejaculation were
treated with ephedrine or, in case that ephedrine failed to convert re
trograde ejaculation into anterograde ejaculation, with imipramine. Po
sitive results were obtained in 5/17 (29.3%) patients, i.e. in 3 (17.6
%) and 2 (11.7%) patients on ephedrine and imipramine, respectively. T
he daily dose of ephedrine was 50 mg and that of imipramine 75 mg, dur
ing a 4-week period. In the group with retroperitoneal lymphadenectomy
, after treatment with ephedrine, only 1 (12.5%) had retrograde ejacul
ation while the remaining patients (n = 7) continued to lack semen emi
ssion. These 7 patients were treated with imipramine, and 3 of them (4
2.8%) achieved anterograde ejaculation. In one third of patients with
retroperitoneal lymphadenectomy and diabetes, with retrograde ejaculat
ion or loss of semen emission, conservative treatment can offer improv
ement or conversion to anterograde ejaculation.
