A second season of the IVF series Big Miracles has been greenlighted for Channel 9.

The docu-series, narrated by Lisa McCune, follows couples and individuals trying to fall pregnant against the overwhelming odds, through IVF and other fertility treatments.

It’s estimated one in six Australians experience the complex realities of infertility, and Big Miracles captures some of these raw and emotional journeys through the world of IVF treatment.

“Our audience loved the first series, and we look forward to working with Ronde Media for another season,” Nine’s Head of Content Production & Development, Adrian Swift said.

No word on a premiere date yet but all episodes of season one are available to stream for free on 9Now.
