Differences in the Spinal Command of Ejaculation in Rapid Ejaculating Rats

Our results provide the first scientific evidence supporting a neurophysiological difference between “rapid,”“normal,” and “sluggish” ejaculators, expressed as an accelerated expulsion phase in “rapid” ejaculator rats. This bridges the gap between a sexual behavior trait and the spinal command of ejaculation. Borgdorff A, Rössler A-S, Clément P, Bernabé J, Alexandre L, and Giuliano F.
