It is generally not necessary to store the placenta, and it should be avoided if the mother has an infectious disease. The placenta is an accessory product of the fetus, and will be expelled together with the fetus when it is delivered. Usually, the placenta has no efficacy or function after delivery, so there is no need to save it. If the mother has an infectious disease, such as AIDS, syphilis, viral hepatitis B, etc., the placenta cannot be preserved, and in this case, it needs to be handed over to the hospital for pollution-free treatment. It is usually necessary to save the placenta. For pregnant women who wish to save the placenta, they can find a specialized preservation institution to save the placenta in a low-temperature environment. It is recommended that the placenta be handed over to the hospital for disposal after delivery, so as to avoid throwing it away privately.
