The reality show, which documents the lives and careers of WWE performers Nikki and Brie Bella, has focused considerably on the six-year romance between Nikki Bella and Blockers star Cena. However, one big issue that the pair saw for their future was Bella's desire to have children — something Cena did not seem to want in the same capacity. In fact, Cena previously underwent a vasectomy, making him unable to father children unless he has the procedure reversed.
