On Tuesday's third episode of Geordie Hospital, male fertility expert Kevin McEleny carries out a delicate operation to help young couple Karl Watson and Bethany Crawford on their quest to have children.
Kevin, a urology surgeon, featured on TV as he explained the op that successfully retrieved sperm from Karl - who has cystic fibrosis - and enabled the couple to move forward and look to take up IVF treatment.
Though the details of the procedure may induce a wince - Kevin slices into the scrotum of patients in search of sperm he can retrieve - the top medic explained how much of a difference it could make for couples like Karl and Bethany.
