According to these evidences, inhibiting the LH synthesis or release may lead to copulatory

complex and ventral bar, but differs from dorsal bar (Y-shaped) with ends modified.
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".
However, still very little is known about the male copulatory
bulb structures, the homology between ground spiders and other related spider groups, and the role of these structures in the mating process.
Genital morphology, copulatory
mechanism and reproductive biology in Psilochorus simoni (Berland, 1911) (Pholcidae; Araneae).
On other hand, when observing the posterior end of the copulatory
segments or the end of the abdomen in males, the shape of the gland was completely different, like dark spots, which could not be easily separated.
Computer programs to analyze brain electrical activity during copulatory
pelvic thrusting in male rats.
Based on the development of the oostegites (brood plates) and male copulatory
stylet, females and males, respectively, and other criteria were categorized as juvenile below 3.
The sexual behavior of the male rats was studied as explained elsewhere, (26) the copulatory
behavior of the male rat was characterized by a series of mounts with or without vaginal intromission from the rear of the female approximately once in every 30 to 120 sec, that eventually culminates in ejaculation.
On the contrary the subchronic treatment failed to exert a significant influence on copulatory
An ejaculation occurs after 6-15 intromissions and is followed by a period of 5-10 minutes post ejaculatory interval during which the male is refractory to further copulatory
A fat, cobby, soup platehooved mare has her place in history as the female who taught the world's most eligible equine bachelor the facts of copulatory
Cirrus 36 (29-48, n = 12) long; accessory piece associated with half of the copulatory
organ, 30 (25-38, n = 12) long.
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.
