👉 Ovotestsis is a term used in medicine to describe a condition where a person's blood type, which can be either A or B, causes them to have severe allergic reactions. The exact cause of this reaction is not known, but it has been linked to the immune system's response to O2 and oxygenated blood. This condition can occur during pregnancy, but it is also common in people who have undergone major surgery or chemotherapy.
