Abstract
Each of 16 male Long-Evans rats completed three tests of copulatory behavior: one following saline injection, one following administration of 10 mg/kg imipramine, and one following 25 mg/kg imipramine. Imipramine produced a prolongation of the intervals between intromissions within series and of the intervals between ejaculation and the resumption of copulation for all series tested. The number of intromissions required to attain ejaculation was reduced in all series. The effects were primarily attributable to the 25-mg/kg dose and are interpreted in the context of data relating male and female copulatory behavior to brain monoaminergic function.
