Abstract:
Male rats sexually inexperienced to 16 months of age and subsequently kept in cohabitation underwent fertility and copulation tests between 16 and 20 months of age. Control males were raised in cohabitation from puberty. At 20 months of age the rats were killed and their accessory reproductive organs were removed and weighed. All but one of sixteen inexperienced males fathered litters between 16 and 17 months of age; there was no significant difference in the ability of both groups to impregnate females caged with them. However, in 15 min copulation tests the sexual activity of the previously inexperienced males was significantly inferior to that of the experienced males. At 16 months of age the inexperienced males showed hardly any sexual activity; gradually their activity increased and between 19 and 20 months of age it reached a level not significantly different from that of the control group. At 20 months, of all the accessory reproductive organs, only the mean penis weight of the inexperienced males was significantly smaller than that of the control group. It is concluded that in male rats aged 16 months or more continuous heterosexual contact is needed to maintain a maximal potential for sexual behaviour. © 1967.

The sexual behaviour of male rats unmated to 16 months of age
Male rats sexually inexperienced to 16 months of age and subsequently kept in cohabitation underwent fertility and copulation tests between 16 and 20 months of age. Control males were raised in cohabitation from puberty. At 20 months of age the rats were killed and their accessory reproductive organs were removed and weighed. All but one of sixteen inexperienced males fathered litters between 16 and 17 months of age; there was no significant difference in the ability of both groups to impregnate females caged with them. However, in 15 min copulation tests the sexual activity of the previously inexperienced males was significantly inferior to that of the experienced males. At 16 months of age the inexperienced males showed hardly any sexual activity; gradually their activity increased and between 19 and 20 months of age it reached a level not significantly different from that of the control group. At 20 months, of all the accessory reproductive organs, only the mean penis weight of the inexperienced males was significantly smaller than that of the control group. It is concluded that in male rats aged 16 months or more continuous heterosexual contact is needed to maintain a maximal potential for sexual behaviour. © 1967.
