Mr Hefner, 86, tied the knot with Crystal Harris, 26, on December 31 and now wants to expand their family by having a child.
"Crystal's desperate to have Hugh's baby. She thinks it would be the most beautiful way imaginable to show him how much she really loves him," dailystar.co.uk quoted a source as saying.
Mr Hefner has also shown similar intentions and has been telling family and friends about it.
"Hef is insisting he's still man enough for the job, telling family and friends at the wedding he's still up for it," the source said and added: "He wants to show the world that age shouldn't stop you from doing anything."
