Myth or Fact ?!

In the Latino culture I have heard of many women not being able to get pregnant due to them having an "open" hip. (La cadera abierta) and wont be able to conceive until someone (that knows how to) massages it into place.(sobarse) Has anybody else heard/experienced this ? I want to know if is true because a lady told me that is the reason I cannot get preggers! ! 😒
