Red wine could hold the key to beating premature ejaculation… but men shouldn’t reach for the bottle yet.
Research suggests a flavonoid abundant in grapes, as well as onions and green tea, helps men last longer in bed.
Twelve straight men — all of whom struggled in the bedroom — were asked to take a daily pill containing quercetin, as it is known.
The tablet, which the volunteers took daily for 12 weeks, also contained an extract of St John’s wort, called hypericum perforatum.
Experts in Spain found the men, who tended to finish within two minutes, could last nearly 77 seconds longer.

What is premature ejaculation and how is it treated?
Premature ejaculation is where a man ejaculates too quickly during sexual intercourse.
There is no strict definition of how quickly a man must ejaculate for it to be considered an issue with it instead left up to couples to seek help.
While occasional episodes of premature ejaculation are common and not a cause for concern men are encouraged to get help find if about half their attempts at sex end prematurely.
What causes premature ejaculation?
It can be be caused by either a physical or psychological issue.
Physical causes include: prostrate or thyroid problems and drug use
Psychological problems include: depression, stress and anxiety
How is it treated?
The NHS advises that men can try masturbating before sex or use a thick condom to last longer.
Various sex techniques to train men to last longer in bed are also available, are as some medications such as antidepressants or Dapoxetine.
The researchers, of the Murcian Institute of Sexology — a private health care centre which treats a variety of sexual disorders, were unable to prove the pill was to thank.
And the study was funded by New Wellness Concept S.L. which provided the pills for the study under its brand Myhixel.
One of the authors is also financially involved in the company, which sells packs of the pills online for about £31.
Nonetheless, sexual health experts are desperate for a cure to premature ejaculation, considering up to one in three men will experience it in their lifetime.
Currently premature ejaculation sufferers are offered a number of treatments to cure the condition.
These include physical steps to decrease sensitivity during sex, addressing psychological issues like depression to prescribing medications called selective serotonin reuptake inhibitors, which can delay ejaculation.
The study on the quercetin/hypericum perforatum pill was originally published in a virtual conference on sexual health in November last year.
An abstract of the paper, which hasn’t been peer-reviewed, was stuck online in The Journal of Sexual Medicine.
Dr Jesús Rodríguez and colleagues were hopeful the tablet would work because quercetin has previously been shown to improve the condition of patients with inflamed prostates, who often experience similar symptoms as premature ejaculation patients.
Likewise, separate studies had shown St. John’s wort inhibits contraction of the vas deferens, a tube inside the penis involved in ejaculation.
All of the heterosexual volunteers in the study, aged between 27 and 58, had been in relationships for at least six months.
The men, who were being treated at the clinic lasted 1min and 9.6secs, on average.
After 12 weeks of taking the pills, the men then re-timed how long they lasted in the bedroom.
The average time to ejaculation increased to 2mins and 26.4secs, according to the authors.
And there were no adverse effects reported, the study claimed.
However, it is unclear how long the improvement — if proven to be genuine — lasts.
Dr Rodríguez and team said bigger, better-controlled longer studies are needed.
It is also unknown if the men got any other treatment for their premature ejaculation during the study although they were not allowed to have any other medication or psychological treatment in the six months prior to recruitment.
The tablets contained around 433.64mg of the St John’s wort extract and 68.65mg of quercetin.
This is roughly the same amount of quercetin as around 85 100ml glasses of red, or as found in one large raw red onion.
