You are being impatient. Many Cucurbitaceae will produce male flowers before
the female flowers.

In the wild, such a strategy encourages out-breeding with other plants (and
genetic diversity) but frustrates the impatient gardener expecting fruit.

Hi

I have several marrow plants which have lots of male flowers, but no
females
(with fruits) - have I done something wrong or am I just be impatient?

Many thanks

Sue
