Previous history of PID
Multiple factors contribute to the relative risk of ectopic pregnancy. In theory, anything that hampers the migration of the embryo to the endometrial cavity could predispose women to ectopic gestation. The most logical explanation for the increasing frequency of ectopic pregnancy is previous pelvic infection; however, most patients presenting with an ectopic pregnancy have no identifiable risk factor. The following risk factors have been linked with ectopic pregnancy.
a. Pelvic inflammatory disease
b. History of prior ectopic pregnancy
c. History of tubal surgery and conception after tubal ligation
d. Use of fertility drugs or assisted reproductive technology
e. Use of an intrauterine device
f. Increasing maternal age
g. Salpingitis isthmica nodosum
h. Other risk factors include previous diethylstilbestrol (DES) exposure, a T-shaped uterus, prior abdominal surgery, failure with progestin-only contraception, and ruptured appendix.
