The short explanation
It is possible, though it is not the most common reason. A C-section can occasionally leave a small pouch or defect in the scar, sometimes called a niche or isthmocele, where blood or fluid collects. This has been linked with spotting after periods and, in some women, difficulty conceiving. Adhesions after surgery can sometimes affect the tubes too. Many women conceive easily after a C-section, so other causes are usually checked as well.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Other factors include age, ovulation, thyroid function, weight, and your husband's semen quality.
- A transvaginal ultrasound or saline scan can look at the scar. A test of the tubes may be suggested if adhesions are suspected.
- Treatment, if needed, depends on what is found and may include surgery to repair a scar defect or fertility treatment.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell whether your scar is affecting fertility. A scan and full evaluation are needed.

- Could my C-section scar be causing a problem, and how would we check?
- Do I have spotting that suggests a scar defect?
- Should my tubes be tested?
- Should my husband also have a semen test?
