Can a trained spleen help with performance, like EPO?

A trained spleen may help with performance enhancement, similar to EPO. According to Bicycling.nl, this would work through natural processes in the body, but the effect has not yet been scientifically proven.
The spleen plays a role in blood circulation and the storage of blood cells. Through specific training, this could potentially have a similar effect to synthetic substances such as EPO. Whether this is really the case is still unclear.
According to the source, more research is needed to confirm the functioning of a trained spleen. The idea sounds promising, but there is still no definitive evidence that the performance enhancement is comparable to EPO.
