difference between male and female bittersweet

Question

I have a bittersweet plant planted last fall. I do not know if it is a male or female. Would like it to produce berries. How do you tell the difference between male and female. I need to get the opposite of what I have.

The female plants produce the berries and it is impossible to tell the plants apart until the vines produce berries.
Reputable garden centers will label and sell the male and female plants.
