Which demographic is most at risk for ectopic pregnancies?

The demographic most at risk for ectopic pregnancies is pregnant females. Ectopic pregnancy occurs when a fertilized egg implants outside the uterus, most commonly in the fallopian tubes. This condition is directly related to pregnancy, making pregnant females the primary group at risk. Factors that can contribute to such pregnancies include previous pelvic inflammatory disease, endometriosis, or surgery on the reproductive organs, which are more likely to be present in females who are pregnant.

While other factors may also play a role in pregnancy complications, the definition of ectopic pregnancy inherently ties it to those currently experiencing pregnancy. Therefore, pregnant females represent the demographic that is specifically at risk for this condition.
