“Contrary to what many people believe, false pregnancy is not only found in women but men as well. When a man suffers a false pregnancy, it is usually called Sympathetic Pregnancy. This is more common when his significant other is pregnant and is dealing with the normal aches and pains that are associated with pregnancy. The medical term when men experience this is called Couvade. Pseudocyesis is extremely rare in both men and women so doctors are still trying to piece together the root cause of the condition.”
