What was studied?
The researchers compared kisspeptin with a control intervention in 29 healthy young heterosexual men, using brain imaging, hormonal measurements and psychological assessments.
What did the researchers report?
Kisspeptin altered activity in brain regions responding to sexual and couple-bonding stimuli. Some changes were associated with measured psychological responses.
What are the limits?
The small, selected sample and mechanistic endpoints do not establish treatment effectiveness for a sexual or mood disorder. Findings should not be generalized to all populations or treated as evidence for a catalog formulation.
