Bourn Hall Clinic in Cambridgeshire, where the first test tube baby was created more than 35 years ago, is one of only a few places in England offering couples three chances of becoming pregnant on the NHS.
The success rate at the fertility clinic is high, with seven out of 10 couples who have treatment there going on to have a baby.
Ben Bland went to meet Jessica Liht and her twins Danielle and Ian, born after treatment at Bourn Hall.
