I don't know the cause, but my Mom had to have operations before being able
to conceive my sister or me. In fact dr's in Israel had told her she couldn't
have children, she hit the ceiling, and she and dad came back to the states,
so I do know I was very much a wanted child.  I am not sure but I think her
problem was endemetrosis. She wanted another after me, but it didn't work,
and she had a hysterectomy.
