Sterilization is a Permanent procedure.
If one Googles 'Depo-Provera', (the apparent agent here) one will see constant use of "Birth Control" but none on page one (as far as I looked) of sterilization.
The First Link in fact is Planned Parenthood and they refer to it (and 3 mo injections of such) as Birth Control.
The same org does describe Sterilization and it's modes and Permanence
Sterilization for Women - Tubal Ligation Procedure - Essure - Adiana ...
As Does the Mayo Clinic
Birth control: Sterilization - MayoClinic.com
Non-reversible, Unlike Depo, which is Temporary Chemical Birth control.
Sterilization would be a surgical procedure.
