Geography: Brown bears are the most widely distributed bears in the world. They are found in North America, Europe, and Asia. Two subspecies of brown bear are native to North America: the grizzly bear (U. a. horribilis) and the Kodiak bear (U. a. middendorffi).
Tubal ligation. 1  There is a slight risk of becoming pregnant after tubal ligation. This happens to about 5 out of 1,000 women after 1 year. 2  Pregnancy may occur if: The tubes grow back together or a new passage forms (recanalization) that allows an egg to be fertilized by sperm.
Most ectopic pregnancies occur when a fertilised egg (ovum) attaches to the inside lining of a Fallopian tube (a tubal ectopic pregnancy). Rarely, an ectopic pregnancy occurs in other places such as in the ovary or inside the tummy (abdomen). The rest of this leaflet deals only with tubal ectopic pregnancy.
