title: Sexual exhaustion in White New Zealand male rabbits of different ages.
abstract: Sexual exhaustion was studied in hybrid White New Zealand rabbits of different ages, for this purpose six young rabbits from 6 to 12 months of age, and six adult rabbits of 14-20 months of age were selected. Sexually receptive females were taken to the male's cage, for a period of 4 min, if copulation was not performed, the observation was then considered finished. If the male mounted within this period of time, the mounted female was immediately replaced by another female and 4 min of exposure time to the male were reinitiated, and repetitions were conducted until the male that was being studied refused to mount a new female at which time the male was considered to be sexually exhausted. Young rabbits mounted and ejaculated 9-10 times before sexual exhaustion. Adult rabbits showed a fluctuation of between 6 and 8 mounts per ejaculations before refusing another mount. The statistical analysis with a Mann-Whitney U-test, showed that the Rank sum for group A was 57, while for group B was 21. The U-value was 0.0 and the adjusted Z -2.9943. A significant difference was observed between groups with a value of P=0.00275. In the present study it was demonstrated that there is an influence of age on sexual behavior of rabbits.
