Infertility caused by a defect in the fallopian tubes is most often related to what condition, according to hysterosalpingography results?

Infertility related to a defect in the fallopian tubes is most commonly associated with pelvic inflammatory disease (PID). PID is an infection of the reproductive organs that can result from sexually transmitted infections or other causes. It can lead to scarring or damage to the fallopian tubes, which obstructs or disrupts the normal passage of the egg from the ovary to the uterus, significantly affecting fertility.

Hysterosalpingography (HSG) is an imaging technique used to evaluate the condition of the fallopian tubes and the uterine cavity. In cases where PID is present, HSG often reveals blockages or abnormalities in the fallopian tubes.

Other conditions such as ovarian cysts, endometriosis, and uterine fibroids can affect fertility, but they do not typically cause direct damage to the fallopian tubes in the way that PID does. Ovarian cysts can lead to hormonal imbalances or affect ovulation. Endometriosis involves the presence of endometrial-like tissue outside the uterus, which can lead to adhesions and scarring but does not primarily affect the tubes directly. Uterine fibroids are benign tumors of the uterus that can impact pregnancy but do not primarily cause fallopian tube damage. Therefore,
