Solving your bedroom woes could soon be as simple as a shot in the arm, according to researchers from Imperial College London.
They found that injecting an aptly-named protein called 'Kisspeptin' into 29 men boosted their brains' response to pictures of couple in sexual situations.
Metro reports that MRI scans showed an increase in activity in regions of the brain stimulated by sexual thoughts and arousal.
Scientists are hopeful that detrimental conditions like anxiety-induced impotence might be helped by an injection of the protein.
Lead researcher Professor Waljit Dhillo also stated that the injection might help to treat emotional factors involved in infertility.
'Our initial findings are novel and exciting as they indicate that kisspeptin plays a role in stimulating some of the emotions and responses that lead to sex and reproduction,' he said.
'Ultimately, we are keen to look into whether kisspeptin could be an effective treatment for psychosexual disorders, and potentially help countless couples who struggle to conceive.'
But the purported benefits don't stop there. Co-author Dr Alexander Comninos also believes that kisspeptin could help to combat depression.
'Our study shows that kisspeptin boosts sexual and romantic brain activity as well as decreased negative mood,'
'This raises the interesting possibility that kisspeptin may have uses in treating psychosexual disorders and depression which are major health problems which often occur together, but further studies would be needed to investigate this.'
Sound promising. Based on their initial success, researchers are now set to recreate their study on women.
