Quality is better than quantity: a comparative study of male mice sexual behaviour
| Resumo: | Sexually reproducing species guarantee the continuity of the species by means of sexual interactions. Animals make use of innate and learned actions to increase the probability of being in contact with an animal of the opposite gender leading to copulatory/consummatory behaviour. After ejaculation is reached, sexual interest is diminished and animals enter a refractory state. Mice sexual behaviour is characterised by a series of mount attempts and mounts-with-intromissions, which in the end eventually lead to ejaculation, with this study we aimed to understand if there were male sexual behaviour between to major subspecies of mices, Mus musculus musculus and Mus musculus domesticus. We showed that there are differences in male sexual behaviour, but unfortunately we could not determine if those differences arise from the fact that this different strains fit in different subspecies of mice. M. musculus females showed to drastically change M. domesticus behaviour making those males necessity less genital stimulation to reach ejaculation (quality versus quantity) and finally with the employed method we could not give more insight about the Prolactin role in establishing or maintaining PERP. |
