Hi,
46, peri, 300mcg patch due to poor absorption prescribed privately, Mirena, T gel.
At a recent NHS appointment I was told that a 100mcg patch shuts down ovarian function. I was aware that at a certain point ovulation can be suppressed by transdermal estradiol BUT not that the ovaries are switched off completely. I pressed the consultant on this, asking if what she was telling me was that I was effectively like a post-meno woman on my current dose, and she said yes.
I've been researching this and this appears not to be the case. A patch may prevent ovulation by flattening the cycle changes that trigger ovulation but the ovaries still produce endogenous estradiol until menopause. If what my consultant said was true then why would anyone need GNrH analogues and add back estradiol?
She also told me I'm at risk of endometrial cancer (I understand there is uncertainty around endometrial protection due to lack of research - but I also know I dont absorb well) and also breast cancer and VTE. VTE is only really a risk with oral preparations as I understand it due to first pass, with transdermal preparations being insignificant.
I understand the narrow parameters of the NHS provision and lack of research means hands are tied but I do object to being given incorrect information which means my blood tests are dismissed as a result. Unless anyone can tell me otherwise?
But what can I do? There feels like there is no comeback, they can say what they want.
