Now, Monk has revealed they are looking into having Stu's vasectomy reversed.
Speaking to news.com.au, Sophie revealed she was also looking into IVF treatment in a bid to conceive.
'[The vasectomy] doesn't really matter because it can be reversed pretty quickly or regardless, I could go freeze my eggs and chuck 'em over to wherever he's got his sperm banked,' Sophie told the publication.
While Stu is already a father of four children with ex-wife Rachel, he has admitted he is keen to start a family with Sophie.
'We have two options but we haven't really discussed them yet,' Stu revealed. 'We should probably go out and have a meal first.'
Despite the show's finale, which aired on Thursday night, being filmed two months ago, Sophie added that she and Stu had barely spent any time together since declaring their true feelings.
'We've only seen each other a couple of times, that's it,' Sophie said. 'And that's hard for two adults - it feels like you're in high school.'
