Where is the ectopic pregnancy?

Ectopic pregnancy may occur outside the uterine cavity, such as the fallopian tube, ovary, omentum, cervix, scar, etc. The details are as follows:

1. Fallopian tube: After the sperm and egg combine to form a fertilized egg, the fertilized egg is significantly hindered in its migration into the uterine cavity. It may then implant and develop in the fallopian tube, causing an ectopic pregnancy in the fallopian tube, which is a relatively common ectopic pregnancy in clinical practice.

2. Ovaries: If the sperm does not combine with the egg in the fallopian tube, it may attach to the ovary through the fimbria of the fallopian tube, combine with the egg to form a fertilized egg, and then cause the gestational sac to grow and develop in the ovary, resulting in an ectopic ovarian pregnancy.

3. Greater omentum: After the sperm swims out of the fallopian tube and combines with the egg in the abdominal cavity to form a fertilized egg, the fertilized egg may implant and develop in the greater omentum, thus causing an ectopic pregnancy in the greater omentum.

4. Cervix: After the sperm and egg combine to form a fertilized egg, it swims into the uterine cavity. If it does not implant in the uterine cavity, it may implant and develop in the cervix, causing an ectopic pregnancy in the cervix.

5. Scar: If a female patient has undergone a caesarean section in the past, after pregnancy, the fertilized egg may implant and develop in the scar area where the incision has healed, causing a scar pregnancy.
