Women often encounter difficulties in getting pregnant after removing the IUD for the following reasons: First, cervical adhesion. If the IUD has been placed for too long, it may cause adhesion or even embeddedness between the IUD and the cervix, and even though the IUD is removed surgically, if the adhesion is not relieved, it will adversely affect the pregnancy. Therefore, it is recommended to perform hysteroscopy, and after diagnosis, medication or surgical treatment may be administered. Second, because of the age of the body hormone level changes, ovarian function or poor quality of egg cells and difficult to conceive, need to be examined and further treatment. Thirdly, the tubes are considered to be the cause of the disease, if long-term chronic inflammation leads to tubal adhesion, stenosis or hydrosalpinx, etc., which will affect the smooth combination of sperm and egg, so it is recommended to carry out laparoscopy or hysteroscopy to identify the cause of the disease and then treat the symptoms.
