Problem with Defender courgettes

I've never had the problem up to now but my co-gardener did.  About two weeks ago, one of the females was finally fertilised. Maybe it's the terrible weather we are having.  Perhaps you could take a look at a few videos where they show you how to hand pollinate courgettes. I just typed "pollinate courgettes" and obtained lots of hits.

The trouble is that I dont have any pollen from the male flowers to use for hand pollination.
