Enlarged Labia Minora - from too much estrogen?

[Borz]

Do you think an enlarged and darkened Labia Minora is caused by too much estrogen and not enough progesterone?

 

[Durey]

That's what I read in a gynaecology textbook once (many years ago, and I don't remember which book). Too much estrogen and a lack of progesterone during puberty is what leads to enlarged, darkly pigmented labia.
