And in particular, women with PMOS have an excess of androgens, and these are so-called male sex hormones.

So these are hormones that are found in higher levels in men than in women, but are also found in women.

But there's an excess of them often in women with this condition.

And that causes an imbalance in other hormones.

You also have things like more insulin resistance.

So you can have high levels of insulin.

High levels of insulin also increase the production of androgens.

So you can see it's like a kind of complex picture.

So research is ongoing to kind of unpick why some people have PMOS.

We know that it can run in families.

So that suggests genes might play a role.

It's unlikely to be a single gene.

It's likely to be many different genes that were involved.

But there are other potential factors as well.

So there's genetic factors.

There might be some nurture factors as well in there.

There are studies, particularly in animals, that suggest that if you've got an exposure, greater exposure to those male sex hormones in the womb, that might increase the risk of offspring having PMOS.

As with many things, if you've got a concern about your health, then a trip to your GP is the first port of call.

And that's also because there are lots of things that can be done to help people with PMOS.

I think it's important to mention that a lot of women have experienced
