Marie and Mirco Martinelli believed they would never be able to have children after suffering three miscarriages in just two years.
They signed up for IVF but were told there was a two-year waiting list for treatment.
So they took part in a trial for DuoFertility, a ground-breaking temperature measuring device that promised pregnancy within 12 months.
They began using the £495 device in January 2009 and were delighted when Marie became pregnant after just seven months.
Baby Alec was born on March 20 this year and is the first baby to be born through the device - which claims to be statistically as good as IVF.
