Delequamine (0.4-6.4 mg/kg; oral, single dose) hydrochloride can increase the sexual behavior score in a dose-dependent manner in a model where untrained male rats are exposed to estrogen-progesterone-treated, sexually receptive female rats. Furthermore, the combination of Delequamine (0.4 mg/kg; oral, single dose) hydrochloride and 8-OH-DPAT (HY-112061) (0.1 mg/kg; subcutaneous injection) can increase the percentage of mounts, intromissions, and ejaculations in rats, shorten the ejaculation latency, and reduce the number of intromissions[1].
