So a lot of people think that it's a male hormone, which it is, but it's also a female hormone.

It's the most biologically active hormone that we have as women in our bodies.

And it affects every single cell in our bodies.

Yet so many people are told again that they can't have it.

They think it's just for libido issues, but it works in every cell.

We've known since the 1940s that it can help with well-being and mood.

And we've got a lot of data since that time that show that mood, energy, concentration, stamina improve when people take testosterone.

If it's given at the right dose to the right woman and the right time, then women often really improve their symptoms and the incidence of side effects is vanishingly low.

So a lot of people seem scared that people are going to walk around with beards and all sorts.

But we don't see it because we replace in a low dose those women who have low testosterone in their bodies with symptoms and it can be transformational.

Obviously, as clinicians, we make sure there's no other underlying cause of their symptoms.

And then we give a trial of testosterone.

And I know personally, if I wasn't taking it, I wouldn't be working as a medical doctor because my brain had gone.

I couldn't remember anything.

I had awful brain fog and fatigue.

worsening migraines.

And I see it a lot in the clinic.

You know, when we've written up a lot of data, we've published data about it as well.

But if you just, in the book, I've written a lot about how testosterone works in the brain and the body.

It's a basic physiological hormone.
