Question

Percentage of ectopic pregnancy seen in fallopian tube is?

• A. 75%
• B. 90%
• C. 80%
• D. 67%

Hint:

The tube dominates ectopic sites, so pick the highest credible figure.

Answer 1

The Correct Option is B

Step 1: When a pregnancy implants anywhere other than the endometrial lining of the uterus it is ectopic, and the overwhelming majority settle in the oviduct.

Step 2: Surveys of ectopic sites show the fallopian tube hosting roughly 90 to 97 percent of them, so the figure closest to reality among the options is 90 percent.

Step 3: Breaking the tube down further, the ampullary part receives most implantations, the isthmus is next, and interstitial and fimbrial pregnancies are uncommon.

Step 4: Quoting 67, 75 or 80 percent falls short of the dominant tubal share, and ovarian, cervical and abdominal pregnancies collectively account for only a few percent.

\[\boxed{90\%}\]
