And then because they're like chemicals in the body, we know they have risks.

They're small risks, but it's important that women know.

So they have a small risk of clot and heart attack and stroke and cancers.

You know, the cancer risk has only been shown with synthetic hormones.

And the risk is small, but actually it's about weighing up whether you want that small risk or not.

And every year women do die from clots and strokes from contraception.

It's a small number, but if it was your daughter, and there was one recently in the BBC, a mother talking about her daughter who died, and nobody had even told her that was a possible risk of taking contraception.

Whereas, as you know, you can't even breathe or say the word HRT with people telling you about all the perceived risks.

So we've written about this on Balance app, actually.

In the UK, there is one that's half body identical.

So it's called Zoli, Z-O-E-L-Y, and it contains estradiol, so not ethanol estradiol.

And actually, in 1979, the WHO announced that there was enough evidence that ethanol estradiol is a carcinogen, i.e.

it causes cancer.

So that's documented.

Good heavens.

So that was why they were trying to promote and push the progestogen only pill.

But that has risks as well.

So the problem is Zoli contains the progestogen is a synthetic progestogen.

So there isn't one that's a pure body identical.

And no one's going to really bring one out because you can't patent it.
