The Risk Factors and Causes Associated with Ectopic Pregnancies

An ectopic pregnancy occurs when the fertilized egg implants in an improper location. Fertilization normally occurs in the uterine tube. Following zygote formation, the fertilized egg then travels to the superior part of the uterus and implants into the endometrium where it can receive proper nutrients and blood supply. This implantation however can occur elsewhere, most commonly the uterine tube, and results in the fetus receiving improper nutrients, ultimately leading to death of the zygote. This process is known as ectopic pregnancy, specifically tubal pregnancy. There are many factors associated with ectopic pregnancies, including hormonal imbalances, fallopian tube inflammation, abnormal development of the fertilized egg, and smoking (Mayo Clinic). Ectopic pregnancies can be specifically harmful when gone unnoticed. If this condition is not recognized and treated promptly, the fallopian tube can rupture and cause fatal consequences. Further research is prompted to further understand the correlation that exists between pathologies found in a donor cadaver, including a history of smoking, cirrhosis, uterine fibroids, and cancers in the lungs, tongue, and skin.
