Identical triplets are conceived when the fertilised egg splits twice. The odds against them occurring without fertility treatment have been put at between one in 60,000 and one in 200million

‘All the help and medical attention we’ve received has been wonderful,’ she added. ‘I’m just so happy they’re all doing so well now.’

Identical triplets are conceived when the fertilised egg splits twice. The odds against them occurring without fertility treatment have been put at between one in 60,000 and one in 200million.

Identical triplets Leila, Liina and Lily Luik, 30, will all compete for Estonia in the marathon at this year’s Olympics in Rio de Janeiro.
