Hay fever symptoms could be alleviated by sexual intercourse, scientists have hypothesised, while admitting their recommendation does suffer from practical obstacles.

Researchers claim that sex constricts the blood vessels which unblocks bunged up noses and clears streaming eyes.

Iranian scientists found the nasal system is linked to the reproductive system.

So far experts at the Tabriz Medical University have not performed clinical trials to test their theory.

But if they are proved right then male sufferers need no longer rely on antihistamine drugs, some of which have been known to cause high blood pressure and blocked noses.

Neurologist Sina Zarrintan claims his method would be a lot more pleasurable, cheaper and need only be done whenever the symptoms become really bad.

He said: "It can be done from time to time to alleviate the congestion and the patient can adjust the number of intercourses depending on the severity of the symptoms."

Not everyone agrees though. Mohammed Amin Abolghassemi Fakhree from Tabriz University poured scorn on the idea.

He added: "There are some limitations in using ejaculation as a treatment of nasal congestion, such as not being applicable out of home and not having any sex partner."
