According to the Daily Mail, Nic previously revealed that complications from his first cancer surgery in 2014 left him unable to conceive naturally.
In a somewhat insensitive comment, the couple said it was 'ironic' that both their respective ex-partners 'struggle having children.'
"Nic had testicular cancer and he's got to do IVF," she said.
Despite the failure of his relationship with Cyrell, Nic appears to be ready for another shot at love on the Channel 9 show.
In April, it was rumoured that the Nic begged the producers of Married At First Sight to allow him to return to the show.
"He loves the drama," a friend dished to New Idea.
"And he totally wants to go back on again."
Nic has also made a full recovery from cancer and is urging others to be on alert for early detection:
"If something doesn't look right or feel right — any aches or pains that don't go away — I'd encourage everyone to get checked as soon as possible.
"Don't put things off and don't have a mentality of 'it'll go away'. It's not always the case that it'll be alright."
And if you're currently suffering from cancer, the reality star also has some advice.
"Always remain positive. Always know that you're better, bigger and stronger than cancer. If family and friends want to be there for you — let them in. Don't push them away. Let love in and take in all the support. You might not think you need it but you do."
After being diagnosed with cancer twice at such a young age, Nic is urging Australians to get behind the Daffodil Day Appeal by the Cancer Council on Friday, August 23 and join the fight against cancer.
"Every person you talk to, they've been touched by cancer or someone they know has," said Nic. "It's just horrific. Daffodil Day is not just about raising money but raising awareness. Cancer is still out there, and we need to fund research and find a way to get rid of it," he added.
The Cancer Council offers information and support, available Monday to Friday, 9am to 5pm, by calling 13 11 20.
