How does ectopic pregnancy occur?

The formation of ectopic pregnancy may be related to inflammatory factors, abnormal fallopian tube structure, drug factors, surgical factors, ovarian cysts, uterine fibroids, etc. The details are as follows:

1. Inflammatory factors: such as pelvic inflammatory disease, vaginitis, cervicitis and other inflammatory factors, which affect the fallopian tubes and cause inflammation, leading to fallopian tube blockage, fallopian tube stenosis, slower peristalsis, and obstruction of the fertilized egg, which may cause ectopic pregnancy.

2. Abnormal fallopian tube structure: For example, the fallopian tube is relatively long. Under normal circumstances, the fallopian tube is 12 to 14 centimeters long. If the fallopian tube is longer than 14 centimeters, the fertilized egg has not had time to be transported to the uterine cavity, and has already developed in the fallopian tube cavity or in the abdominal cavity, which may result in an ectopic pregnancy.

3. Drug factors: For example, taking birth control pills for a long time will cause abnormal secretion of estrogen and progesterone, affect the implantation of the fertilized egg, and may also cause ectopic pregnancy.

4. Surgical factors: For example, some women have had an IUD or have undergone ovarian surgery, which may hinder the transportation of fertilized eggs and easily lead to ectopic pregnancy.

5. Ovarian cyst: Ovarian cysts are relatively large and may compress the fallopian tubes, causing obstruction of the fallopian tubes and inducing ectopic pregnancy.

6. Uterine fibroids: Uterine fibroids are relatively large and compress the fallopian tubes, affecting the delivery of fertilized eggs and causing ectopic pregnancy.

To avoid ectopic pregnancy, you need to eliminate the above-mentioned inducing factors and follow the doctor's advice for treatment.
