I would take with a pinch of salt what the advertising blurb from the people that manufacture Gina says, their world can be miles away from the reality of Vaginal atrophy (GSM) and what is required to control it. For instance I wouldn't advise any woman to just rely on one hard, dry pessary without using a moisturiser when having intercourse. I would also like to say, its not all about, hurray I can have sex again, its much more of a condition than that, but sex sells as they say!
Use your own judgement, you will soon find what you yourself need to control your symptoms, by that I mean use as much of the products as you need, Vagifem, Estriol and a moisturiser.
