Progestin supplementation can be given orally and by injection. Commonly used drugs for oral progesterone include dydrogesterone and progesterone pills. Progesterone injections are mainly used by injection, and progesterone injections are usually given by intramuscular injection. The specific dose and duration of progesterone supplementation will depend on the purpose of progesterone supplementation. If progesterone supplementation is needed for early pregnancy due to preterm miscarriage caused by luteal insufficiency, you can take oral dydrogesterone or progesterone pills. If a woman’s menstrual cycle is to be regulated, she can use postmenstrual half-cycle therapy, or she can take oral drospirenone or progesterone injection, etc. The choice should be made at the discretion of the patient.
