Which factor is NOT a known risk factor for ectopic pregnancy?

• A. Use of diaphragm
• B. Fertility medications
• C. History of Chlamydia
• D. Use of an intrauterine device

Answer: (A)

The factor not increasing the risk for an ectopic pregnancy is a diaphragm. Ectopic pregnancy risk rises with factors that damage or bypass the normal fallopian-tube transport, such as prior pelvic infections (often from Chlamydia), which cause tubal scarring; fertility medications that induce ovulation and can alter tubal transport; and use of an intrauterine device, which is associated with a higher proportion of ectopic pregnancies if pregnancy occurs. A diaphragm is a barrier method that reduces the chance of fertilization but does not damage the fallopian tubes or cause infection, so it does not contribute to ectopic pregnancy risk.
