I'm assuming it's because.... The spleen filters out the blood that's is going throughout the body. Polycythemia is excessive production of RBc. Soo, if there is excessive blood and the spleen is filtering all of it, it is working hard causing it to become enlarge.

Is an extra spleen dangerous and does it require removal?

Can you have kids without a spleen?

Generally, yes. However, since the spleen is a major organ of the immune system and helps protect against encapsulated organisms (eg, Haemophilus influenzae, Streptococcus pneumoniae, Neisseria meningitidis), individuals are susceptible to infections by these organisms following removal of the spleen (also called splenectomy).I am living proof that you can live without a spleen. My spleen was removed at the tender age of 12 (now 49) due to a rare inherited blood disorder (Spherocytosis) which caused my spleen to enlarge. Fortunately these days they will not take out your spleen unless absolutely necessary due the the reason given above. I have received many inoculations and am now taking penicillin for the rest of my life to help with my immune system.
