Unlike other types of organ or tissue transplants from donors, there is virtually no risk of rejection with perinatal tissue injections.

This is a special property of perinatal tissue. Since baby’s body and mom’s body aren’t necessarily biologically compatible, the perinatal tissue is naturally “immunoprivileged,” acting as a defensive barrier to prevent mom’s immune system from mistakenly attacking the growing fetus.

The unintended but very welcome benefit of this state of affairs is that your body won’t attack perinatal tissue either after an injection. You don’t have to be pregnant or even female for it to work.
