behaviour correlates with medial preoptic dopamine release in castrated male rats," Hormone and Behaviour, vol.
In this study, copulatory
actions of ghrelin and its specific antagonist, DLS, were examined.
Testis fusiform; vas deferens dextral; seminal vesicle usually large, lying in midline immediately inferior to copulatory
complex; prostatic reservoir oval.
In this frame, the authors highlighted the lack of any copulatory
lamella in the internal sac of Copris, and the presence of two well differentiated accessory lamellae, named (according to the nomenclature created by Binaghi et al) "parietal accessory lamella" and "(conic) external lamella".
The term epigynum refers to the external parts and the term vulva refers to the internal parts of the female copulatory
mechanism in Holocnemus pluchei and Pholcus opilionoides, with notes on male cheliceral apophyses and stridulatory organs in Pholcidae (Araneae).
The results also conveyed a decrease in the number of intromissions and an increase in the number of mounts, thus leading to a decrease in the copulatory
Ageneral increase in all evaluated parameters of copulatory
behavior was observed in treated animals in comparison with vehicle ones.
Males that had undergone the sixth molt, corresponding to the presence of palps differentiated into copulatory
organs, were housed with females in order to observe whether the animals in this phase of the development already demonstrated mating behaviour, which would demonstrate their sexual maturity.
These measures are confounded by the erectile processes (i.e., potency) necessary for successful execution of copulatory
Other subjects include copulatory
structures, signaling and courtship, adaptation and evolution of reproductive mode in copulating cottoid species, fertilization, sex determination, and parental care, as well as reproduction in relation to conservation and exploitation of marine fishes, cryopreservation of gametes, embryogenesis and development, and molecular genetics of the development of the Zebrafish.
