A spinning nozzle is provided for the extrusion of a hollow fiber from one or more spinning masses. An apparatus that includes a spinning nozzle, and a method for extruding a hollow fiber using the spinning nozzle, are also provided. The spinning nozzle has an inlet port for each spinning mass to be extruded. The inlet port is for introducing the spinning mass into the spinning nozzle. An outlet port for the exit of a spinning mass along an outlet axis, is also provided. A spinning mass flow channel is used to guide the spinning mass from the inlet port to the outlet port. The spinning mass flow channel includes a flow manipulation section having an inlet and an outlet and includes a flow-guiding structure for influencing a spinning mass through the spinning mass flow channel.
