2.4. Antepartum management
PRETERM BIRTH
After 6 months of adenomyomectomy, participants could try to conceive and the method of pregnancy was left to the patients’ preference, including natural means or ART.In antepartum, to prevent preterm birth and uterine rupture during pregnancy, progestin treatment was provided to all patients for up to 34 weeks of gestation. They were administered vaginally once a day (Utrogestan, vaginal capsule 200 mg, Hanwha Pharma, Seoul, Korea) or injected intramuscularly every week (Progesterone Depot 250 mg, Jenapharm, Jena, Germany), depending on the patients’ preferences. A cesarean section was recommended as the delivery mode. Delivery timing was individualized, but we generally planned for birth at the early term in accordance with the recommendations set by the American College of Obstetricians and Gynecologists.
