Perhaps a dumb question, but how exactly does an abdominal pregnancy occur? The Wikipedia page is really unclear. The text sounds as if this can happen without a rupture to the uterus or a fallopian tube.

'Ectopic Pregnancy' is the more general term for pregnancy outside the uterus. Found this, hope it helps. 'Typically an abdominal pregnancy is a secondary implantation which means that it originated from a tubal (less common an ovarian) pregnancy and re-implanted.' https://en.wikiversity.org/wiki/WikiJournal_of_Medicine/Insights_into_abdominal_pregnancy#Mechanism https://en.wikiversity.org/wiki/WikiJournal_of_Medicine/Insi... "An ectopic pregnancy occasionally aborts backwards down a tube, or bursts out of it without killing the patient, and embeds itself elsewhere in her abdominal cavity. Sometimes, an ovum is fertilized outside a tube on the surface of an ovary, and then implants itself in the abdominal cavity. ... An abdominal pregnancy is thus a rare complication of an ordinary ectopic pregnancy" https://web.archive.org/web/20170814131930/https://www.meb.uni-bonn.de/dtc/primsurg/docbook/html/x5173.html https://web.archive.org/web/20170814131930/https://www.meb.u...

  Thanks. The missing piece for me was that the Fallopian tubes are not directly connected to the ovaries, which makes “an ovum is fertilized outside a tube” an understandable scenario.

IANAD but I know the fallopian tube doesn't connect to the ovaries but instead opens into the abdomen. An already ectopic embryo could continue up the tube until it exits into the abdomen. That sounds crazy which is probably why it's so rare. Also, during ovulation, a fringe called the fimbra is deployed to essentially sweep the egg into the tube.

  Thanks. I feel like sex ed really failed me here. I did not realize the fallopian tube didn't connect directly to the ovary. This makes abdominal pregnancy without something rupturing seem a lot more plausible.
