| Popis: | The penile reflex in sexually experienced male rats aged 10 and 44 weeks was observed for 20 min following sheath retraction. All 7 males aged 10 weeks showed erections, cups arid flips, while of 5 males aged 44 weeks only 2 showed erections. Frequencies of the above behaviors in aged males were significantly lower than that in young males. The decrease of penile reflexes with aging was similar to that of copulatory behavior with aging, when paired with receptive females. The present study is the first to clearly establish the pattern of penile reflexes in aged rats. Scandinavian Journal of Laboratory Animal Sciences, Vol. 26 No. 2 (1999) |
