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.
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).
Based on the development of the oostegites in the females and the copulatory
stylet in males below 3.
An ejaculation occurred after 6-15 intromissions and was followed by a period of 5-10 minutes post ejaculatory interval during which the male is refractory to further copulatory
4) Post-ejaculatoiy interval (PEI): time from ejaculation to the first intromission of the second copulatory
potency) necessary for successful execution of copulatory
Gutierrez and Suriano (1992) added generic characteristics and Kritsky and Gutierrez (1998) proposed an emended diagnosis which characterizes Demidospermus as species having: tandem gonads; counterclockwise coiled male copulatory
organ; sinistral vaginal aperture; U-, W-, or V-shaped haptoral bars; subspherical eye granules and a sheath like accessory piece serving as a guide for the male copulatory
For example, the medial preoptic area (MPOA) has been shown to be important for sexual arousal, copulatory
behaviour, and the refractory period of male rats (Hoffman, Gerall, & Kalivas, 1987; Oomura, Aou, Koyama, Fujita, & Yoshimatsu, 1988).
The structure, function, and postembryonic development of the male and female copulatory
organs of the black widow spider Latrodectus curacaviensis (Muller).

performance of Male Rats Produced by repeated peripheral shock.
