Recent research analyzing brain activity in mice during mating has shed light on the intricate chemical processes in the male brain during sex. The study discovered a 'dance' between dopamine and acetylcholine, two vital neurotransmitters, influencing sexual progression. Prior research largely focused on sexual initiation, leaving gaps in understanding other phases, such as mounting and ejaculation. The findings hint at potential clinical treatments for premature ejaculation, highlighting the study's significance in connecting basic science with future medical applications.
'I believe our study has opened the door to the development of clinical treatments,' said Ai Miyasaka, a postdoctoral fellow at the University of Tsukuba in Japan and first author of the study.
'Sexual behavior is a complex sequence of events,' explained senior author Qinghua Liu of the National Institute of Biological Sciences in Beijing.
An optic fiber would light up if the brain released dopamine - a chemical often associated with pleasure - and acetylcholine - a neurotransmitter known to regulate dopamine.
The results revealed an intricate dance between the two chemicals at every stage.
