Wild grape leaf shape question

[biwa]

I have several wild grape vines growing in my yard, and I've noticed that the leaf shape varies by plant. I am wondering, can I use the leaf shape information to determine the sex of the plant?

This one is growing on the south side of my house:

It is evidently male (it flowers but never sets fruit). All of the leaves are single-lobed.

This one is growing on the west side of my house:

It is too young to flower. The leaves have 1, 3, or 5 lobes. Does the different leaf shape on this plant indicate it is female?
