This is a very common issue with infant girls. This is called labial adhesions, and you don’t need to worry about this unless the opening is entirely closed. These adhesions are thought to happen because of a NORMAL lack of circulating estrogen in a young baby. These adhesions almost always open up with time, but sometimes the Doctor will prescribe an estrogen cream to be applied for about two weeks to help the process. There is a potential side effect of the cream: faint pubic hair growth – which doesn’t happen very often. If this does happen, you simply stop the cream.
“At our 1 year old little girl’s last appointment with her dr she said that her vagina was closing. I was wondering what causes this and what happens if it keeps staying like that and what can your dr do to it so that it will open b/c me and my husband never heard of this and it?s kind of scary.”
