Dopamine Circuit in Brain Found to Drive Male Ejaculation

New research uncovers how dopamine in the ventral shell of the nucleus accumbens (vsNAc) governs the sexual behavior sequence in male mice, from sniffing to ejaculation. Using fiber photometry, scientists identified rhythmic dopamine activity during intromission that aligns with movement patterns and is regulated by acetylcholine inputs.
