According to a new study from Imperial College London, the hormone bispeptin causes a person to get excited and want romance.
What is kispeptin? It is a natural hormone that allows the body to produce other reproductive hormones.
In the study, men were treated with kispeptin or placebo, then they showed sexual and romantic images of couples (in addition to neutral images of couples) and underwent an MRI scan of the subjects' brain.
The researchers found that the guys who entered Kispeptin, had increased brain activity in areas associated with sexual arousal and romance.
Based on the results of the study, scientists suggest that kispeptin can help people with psychosexual disorders and people who have problems with conception.
In addition, kispeptin able to fight depression. During the study, participants observed not only sexual and romantic photos, but also happy, scary, neutral and negative images.
While kisspeptin does not affect the emotional activity of the brain, when a person sees neutral, happy, or scary pictures, the hormone has increased activity in the areas of the brain that regulate bad mood.
Participants themselves reported that they came out after the experiment in a better mood than before the injection and scan.
