Will small uterus cause infertility? Can women with uterus 30mm*27mm*37mm get pregnant? Cavity length is 21mm. Will it cause any problem during pregnancy?

Fertility evaluation. There is no set definition of a small uterus. Consider seeing a fertility specialist so that your case can be evaluated one on one. You will want to find out if your uterus is just small or if there appears to be a uterine anomaly or some form of uterine hypoplasia. After a proper evaluation questions regarding future fertility can be addressed.
