Oh wow, thanks Lori-Dee. That's all extremely helpful information.
As well as the issue about adhesion, I hadn't considered the idea that the patches wouldn't deliver sufficient dosage. I think they're available in four different strengths in the UK so it will be interesting to see what my Gender Clinic advocate.
I have a cis female friend who has no problems with Evorel patch adhesion but I guess it's going to be a case of trying them out, with regular hormone level monitoring in the early stages.
I have reached the point where the gels are pretty invasive. My morning dose is the higher of the two and applied to my thigh. This means I have got into an ingrained habit of waking early (3.30 or 4 am) to apply the dose, waiting an hour or more for it to dry, and then going back to sleep. This has been going on for more than two years and it's a bad sleep pattern. Then the afternoon dose involves hitching up a sleeve and spreading it over my arm: hardly ideal if you are out and about. And both doses require careful planning with baths or showers.
