Trufflecat and Tinnkerbellj, I would add that nobody has even come close to being able to come up a reasonable, logical explanation as to why the NHS does not licence the use of Utrogestan vaginally. I couldn't care less because I am going to use it vaginally anyway but why don't they just change it? Just about every other country licences it to be used in this way so why not the NHS? As you say, Professor Studd and other private doctors do.
It seems to me that many women should not be using Utrogestan orally at all and of course 50% of it gets lost in your digestive system anyway so it is not as effective as using it vaginally whereby nearly all of it hits the spot i.e. the womb.
