What factor significantly increases the likelihood of an ectopic pregnancy in a patient with abdominal pain and vaginal bleeding?

• A. Cigarette smoking
• B. Habitual abortion
• C. HIV seropositivity
• D. Previous gonorrhea infection

Answer: (D)

An ectopic pregnancy occurs when a fertilized egg implants outside of the uterine cavity, commonly in the fallopian tubes. Several factors can increase the risk of this condition. A history of certain sexually transmitted infections, particularly past gonorrhea infection, significantly contributes to the likelihood of an ectopic pregnancy. This is because gonorrhea can lead to pelvic inflammatory disease (PID), which damages the fallopian tubes, creating anatomical changes that can impede the normal transport of the fertilized egg and lead to abnormal implantation.

When there is scarring or blockage in the fallopian tubes due to PID, the risk of the fertilized egg implanting outside the uterus increases. This makes a history of gonorrhea infection a critical factor influencing the risk of ectopic pregnancy.

While cigarette smoking, habitual abortions, and HIV can also have associations with reproductive health and potential complications in pregnancy, their connection to directly causing ectopic pregnancies is not as pronounced as that of a previous gonorrhea infection, which is more closely linked to the physical conditions that predispose a patient to ectopic implantation.
