Is there a difference in quality

It doesn't take much to confuse me, rary, but I'm with Snadger. Why would you want to add fertiliser to your compost heap?
Fertiliser is for plants. Maybe add a bit when you're setting your plants out but adding it, willy-nilly to your compost heap seems pontless. Not all plants need Farmer's Fertiliser anyway.
I'm assuming you got it free and are trying to find a way to use it.

Surely you aren't insinuating Rary is a tight git?

I make compost every year from all the allotment waste. I get my husband to (surreptitiously) pee in the compost bins because I (for some reason....... lost on the mists of time) believe male urine contains lots of Nitrogen and accelerates the compostmaking. This is probably some old wives tale that I have taken on board in the distant past. I also add lots of cut comfrey leaves. I can only presume that at least I am doing no harm. I wouldn't dream of adding commercial fertiliser to my compost but I have no real reason for this. It would be interesting to know how to make the best compost possible.

All urine contains plenty of nitrogen. Male or female makes no difference.
Getting rid of excess nitrogen (in the form of urea) from the body is one of the primary purposes of urine.
It depends on the "strength", though. The more yellow it is, the more urea it has, and therefore the more nitrogen.

With the male part, you may be getting mixed up with the idea that male urine is meant to help keep foxes and the like away, as it apparently has various pheromones in it that tell the animals that territory is taken.
How much truth there actually is to that, I don't know. I feel like it wouldn't work, as humans are a completely different species, and thus foxes and badgers and such aren't adapted to recognize human pheromones, but I admit I don't have any evidence.

Yes she is
and yes VC I did

The high nitrogen stuff would act as a compost accelerator, which may be desirable.
But otherwise, it's not really the best idea as it's just wasteful. Chemical fertilizers are water soluble, so if you add it to the compost heap then most of it is likely to get washed out by the time you actually use the compost.

Any compost I make is made in a box so any fertiliser added to it won't get washed out, also as I now use manure and seaweed to fertilise the garden and I have several packs of chemical fertiliser which I don't intend to use and definitely won't be throwing out I don't consider using it to make compost as wasteful

Unless your compost bin has a water-tight base and sides, it's still likely to get washed out.
And if you're saying it does have a water-tight base and sides, how do you cope with water pooling at the bottom and water-logging the compost?

^^^^^^^ The bin is made of plastic, and I use a lot of cardboard and paper which soaks up a lot of moisture
