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.
02 / FINDINGS
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.
03 / LIMITS
How should it be interpreted?
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.
