Ectopic pregnancies also called extrauterine, are pregnancies in which the embryo implants outside the uterine cavity. In this case, the most frequent location of the ectopic pregnancy is the fallopian tube.
There are some known risk factors that can increase the risk of ectopic pregnancy, such as:
- Pelvic inflammatory disease.
- Intrauterine device (IUD).
- Previous ectopic pregnancy.
- Advanced maternal age.
In addition, assisted reproductive techniques and prior tubal surgery may also increase a woman's chance of having an ectopic pregnancy.
