jewterus 

anatomy. Nontechnical name: womb, a hollow muscular organ lying within the pelvic cavity of a Jewish female human. It houses the developing fetus and by contractions aids in its expulsion to create a baby which is considered 100% Jewish by Jewish ritual law, regardless of the religion of the father.

Jewess: My parents want their grand kids to be Jewish, but they say I can marry outside the faith because I have a jewterus, which automatically makes any offspring I produce 100% pure Jewcy.
