Scalloped edge pan courgettes

Hi
Ive read the old thread about these types being less productive but just wanted to ask if you are supposed to remove the female flowers. Currently have two huge plants, lots of flowers but only one courgette forming. Sure ive grown them before ok but on a different plot. They are next to butternut squash which have too many fruit forming so?
Much appreciated 

Thanks Mumofstig,
Think i may have confused my genders there, the ones with long stem and flower LOL. I was looking forward to having some as they are the only ones i've grown this year,
Oh well, maybe next year  👍🐝😞

Hi Vagabond,
glad I'm not the only one who forgets what varieties I've planted.
I bought a spirallizer expecting to make cougetti so guess i'll have to buy them 😞
