The story of the word

Mḗtra is womb, from mḗtēr, mother, so the family relation is folded into the anatomy. Endometriosis is the same tissue growing where it should not, a condition affecting roughly one woman in ten of reproductive age and still taking years, on average, to name. The muscular wall outside it is the myometrium, from mŷs, muscle.
