A hormone found in chocolate may boost men’s sex drive

  • Kisspeptin may even improve men’s sexual performance, scientists now think.

Doctors in the future may treat men suffering from low sex drive with an injection of a hormone found in chocolate.

A new study has just found kisspeptin boosted how men’s brains respond to attractive faces and scent.

It could help the one-in-three people who suffer from ‘psychosexual disorders’. These include not getting aroused or satisfied by sex.

Why might kisspeptin help?

Kisspeptin is found in chocolate and takes its name from Hershey’s Kisses. That’s because the scientists who originally discovered it were in Pennsylvania State University, close to the Hershey’s factory that makes chocolate ‘Kisses’.

In the new study, scientists from Imperial College London wanted to discover if the hormone could combat ‘sexual problems’ like low libido in men.

So they gave either kisspeptin or a placebo to 33 men, aged 18 to 34. They then showed them attractive images of faces and let them smell perfume. Meanwhile, the scientists scanned their brains in an MRI scanner.

The journal JCI Insight has now published the results. And they show kisspeptin ‘enhanced attraction pathways in the brain’.

The scientists admit they ‘still have a long way to go’. And, so far, their study has been limited to heterosexual men. However, they hope it may provide new ways to treat sexual problems.
