Popis: | In general, sexual activity in normal animals declines with increasing age. In aged male rats, for example, no ejaculation occurs when paired with receptive females. The ejaculatory response induced by p-chloroamphetamine (PCA) in aged adult rats, 14 to 18 months of age, was observed. The animals were treated intraperitoneally with PCA. The ejaculation rates were 0.28.6, 57.1 and 100% at doses of 0.3125, 0.625, 1.25 and 2.5 mg/kg, respectively. These animals, with a few exceptions, showed an ejaculation within 2 hrs of PCA injection. These data for aged adults are similar to those for young adults. |
