If progesterone isn't absorbed through the skin, then how is utrogestan absorbed when used vaginally, i mean in effect it it is going through vaginal skin, isn’t it? And while it isn't licensed for use in this way in UK, it is in other countries. Is it because it is in oil or something different compared to topical cream? I always used utrogestan vaginally and would say that I had the opposite problem of too much absorption.
