Sexual Satiety
Experiment #1: Do the number of ejaculations prior to the occurrence of long intromissions make a difference in the pattern of c-fos expression?
Design:
- compare pattern of Fos-immunostaining within sexually experienced male hamsters mated to long intromissions in 2 groups: 1) rested male hamsters (rested 1 week), and 2) male hamsters mated to long intromissions on 4 consecutive days prior to experimental day
- rested male hamsters show more ejaculations (on average 9 ejaculations) while repeatedly mated males show fewer ejaculations (on average 4 ejaculations)
Results: (focus on neuronal cell “clusters” in cMePD)
- males mated to long intromissions in both groups (rested male hamsters and repeatedly mated male hamsters) showed the presence of neuronal cell clusters in cMePD
Conclusion:
- the number of ejaculations does not alter presence of neuronal cell“clusters” in cMePD
