The Full-Term Delivery of a Normal Female Infant by a Woman with a Levonorgestrel Intrauterine System in Situ and Identified as Having Uterine Adenomyosis: A Case Report

摘要

This study reports an IVF patient who had adenomyosis underwent 2 in vitro fertilization (IVF) cycles and 3 frozen embryo transfer (FET) cycles but all failed. Then a Levonorgestrel-releasing intrauterine system (LNG-IUS) was inserted into her uterine. When her next menstrual period did not occur, the patient performed a urinary pregnancy test and it was positive. The pregnancy progressed normally and the delivery was uncomplicated. An elective Caesarean delivery was performed at 39 weeks gestation. The IUD was found in the placenta and the postpartum recovery was uneventful. This is the first report of a woman, who having been identified with uterine adenomyosis, delivered a normal female infant with an LNG-IUS in situ. This case report indicated that LNG-IUS may play some roles in changing the uterine environment of adenomyosis.
