Does anyone know how to modify the width of an MDSegmentedControl?

MDSegmentedControl:
                pos_hint: {"center_x": .5, "center_y": .5}

                MDSegmentedControlItem:
                    text: "Homem"   
                    font_size: "12sp"
                MDSegmentedControlItem:
                    text: "Mulher"
                    font_size: "12sp"
                MDSegmentedControlItem:
                    text: "Outros"
                    font_size: "12sp"
