Sharon, I have a daughter with CAH, and I have a non-CAH daughter with labial adhesions. It is very common, and the treatment your doctor ordered is also common. A lot of times, just using the cream for several days will cause the vagina to reopen. When my CAH daughter was born, I just assumed that she had the same problem that her older sister had (the doctors did not notice that she had no vaginal opening until I showed them.) I now know that it couldn't be the same thing for this reason - the vagina closes due to a lack of estrogen. When a baby is born, she has all the hormones from her mother, so it cannot be the same thing. The gene mutation that causes classical CAH is different from the one that causes late onset CAH. It has happened before, that a family would have affected children with two separate gene mutations, but it is extremely rare. If the cream works, and the vagina reopens, it is not CAH related - it is an estrogen problem.
