Which is a key risk factor for tubal infertility?

• A. Prior pelvic inflammatory disease (PID)
• B. Diet high in sugar
• C. Regular exercise
• D. Adequate sleep

Answer: (A)

Tubal infertility occurs when the fallopian tubes are scarred or blocked, preventing the egg and sperm from meeting or the embryo from reaching the uterus. Prior pelvic inflammatory disease is a major risk factor because PID inflames and inflames the reproductive tract, leading to scarring and adhesions in the fallopian tubes. This damage can narrow or block the tubes and disrupt their normal motion, directly causing infertility.

The other options don’t cause this tubal damage. A diet high in sugar can affect overall health and fertility in some indirect ways, but it doesn’t specifically scar or obstruct the tubes. Regular exercise and adequate sleep are generally beneficial for reproductive health and don’t contribute to tubal obstruction.
