Couples in Denmark are being encouraged to travel to help boost the country’s falling birth rate in a hilarious new advert.

The Do It For Denmark! clip explains how getting away from it all boosts men and woman's libidos – with a therapist claiming nearly half of couples have more sex when on holiday.

And the tongue-in-cheek video says 10 per cent of all Danish children are conceived while abroad – with the producers Spies Travel offering a free holiday to anyone who conceives on one of its ‘ovulation discount’ trips

The voiceover on the Do It For Denmark! campaign asks 'Can sex save Denmark's future?', adding: ‘Denmark faces a problem. 

‘The birth rate is at a 27-year low, and there are not enough children being born to support the ageing population.  

‘Thirty years ago, Emma's parents took a little getaway. If these walls could talk... But it turns out Emma's case isn't so rare. 10 per cent of all Danish children are conceived on holidays.’

The video goes on to interview therapist Birgit Dagmar Johansen, who claims: 'To travel and get new experiences affects relationships because couples see each other in a new light. It releases endorphins in the brain and creates desire for sex. 

‘It's how we get children. In fact, Danes have 46 per cent more sex on holiday compared to their everyday life.’

The voiceover adds: ‘So to help the falling Danish birth rate, Spies Travel wants to encourage all Danes to take a romantic city holiday.

‘After all, it will also help our future business. But if doing it for Denmark isn't enough, we made a little competition. 

'Book your holiday with our ovulation discount. Get it on. And prove you conceived a child to win a three-year supply of baby stuff and a child-friendly holiday.

‘But what if you already did your duty? Or what if your chance of conceiving a children isn't so high? 
‘Well look at it this way. It's not just about winning. All the fun is in the participation. Participate in the competition.

‘Do it for Denmark.’
