Simple treatment could inject new passion into your withering sex life, scientists discover

A HORMONE injection can supercharge the sex life of couples who are stuck in the bedroom.

Two studies found that just two doses of a chemical called kisspeptin increased sex drive in both men and women.

It also helped men rise to the occasion by giving them stronger erections.

Scientists from Imperial College London tested the treatment on 64 NHS patients who were unhappy with their sex life.

Professor Waljit Dhillo said: “It was very encouraging to see the same boosting effect in women and men.”

About one in five Brits has sex at least once a week, according to YouGov polls.

Kisspeptin is a natural hormone that helps the brain focus on arousal and responding to come-ons or signals from partners.

It also reduces shyness when someone becomes aroused by slowing down activity in certain parts of the brain.

Scientists write in the journal Jama Network Open that low levels can make people too confident or embarrassed to be left out — or miss lovers’ cues altogether.

A study of 32 men found their erections increased by 56 percent and scans showed their brains were more aroused by erotic videos after treatment with Kisspeptin.

They were also much more likely to be happy with their sex life.

Calling it life-changing, a 44-year-old participant said, “The week I had the Kisspeptin IV, we conceived our son.”

Separate research on women showed extra brain activity in regions associated with passion.

And they reported feeling “sexy” compared to those without treatment.

Study author Dr. Alexander Comninos said: “Low sexual desire can be distressing and have a major impact on relationships, mental health and fertility.

“Although it is relatively common, treatment options in women are limited and in men there are no treatments currently available or on the horizon.

“We provide the first evidence that Kisspeptin is a potentially safe and effective therapy for women and men with worryingly low sexual desire.”

Scientists are now planning to conduct larger studies to prove that Kisspeptin can be used to improve the sex life of Brits.
