Fruit fly study links dopamine to stress-induced sexual dysfunction

https://www.news-medical.net/news/20260530/Fruit-fly-study-links-dopamine-to-stress-induced-sexual-dysfunction.aspx Scientists from Tokyo Metropolitan University have revealed key parts of the biochemical pathways connecting stress to sexual dysfunction. By studying Drosophila fruit flies, they showed that the neurotransmitter dopamine was responsible for determining how long male flies showed persistent courtship suppression after being confined in a small space, but not whether mating was suppressed in the first place. Their findings in a key model organism illuminate neurobiological factors causing sexual dysfunction in other organisms, including humans.
