In medaka fish, the reduction of cystic proliferation of germ stem cells declines gametogenesis, reproduction success, and male sexual behavior, with a decrease of mating vigor.

Behavioral and in vivo imaging analysis in the fly suggests that mating-related sensory experience regulates female odor perception and expression of choice behavior through a dopamine-gated learning circuit.

Triacylglycerides found in the males of 11 species of Drosophila form a largely overlooked, novel, sex-specific class of pheromones that act to suppress courtship behaviour.

In the brain of medaka fish, neuropeptide B acts directly downstream of estrogen in a female-specific but reversible manner to mediate female receptivity to male courtship.

Melanization of a secondary sexual structure facilitates male mating success in Drosophila.

Male C. elegans die through two distinct mechanisms – mating-induced germline activation, and potent male pheromone toxicity – but the latter is unique to males of androdioecious species (made up of hermaphrodites and males).

Engineering male mosquitoes lacking the fruitless gene induces them to be attracted to humans.

A sexually dimorphic circuit node controls a persistent, internal state that promotes fighting and mating in Drosophila, revealing parallels with mammalian systems suggestive of a conserved circuit "motif" controlling social behaviors.

Studying the development of the medial amygdala in the mouse reveals how the brain may potentially process sex differences in innate behaviors such as mating.

A new tool enables measuring feeding and locomotion simultaneously which will enable insights into environmental, developmental, neuronal, and genetic factors underlying behavioral regulation.
