This is a great story.
A woman thought she could not have children is now a mother - thanks to a white knuckle rollercoaster ride.
Nayade Elbing, 28, and her husband Arnold had been trying to have children for several years without success and believed she was sterile.
But, after making love in their home, the young couple visited their local entertainment park at Hassloch in Germany where Nayade went on the Expedition GeForce, one of the world's fastest rollercoasters.
One week later her gynaecologist, Dr Thomas Gent, told her she was pregnant.
He said: "We believe that she conceived due to the G force of the rollercoaster ride."
In the meantime, Cuban-born Nayade has given birth to a little boy now called Leandro Elias.
The entertainment park gave little Leandro, nicknamed G Force by his dad, a life-long free ticket for rollercoaster rides.
