Is this a male?
Female 
Slightly re-vegging
I can’t tell from the pic. Look more closely at the calyxes at the plant’s nodes. A male will have more than one calyx at each node and the calyxes will be absent pistils. Male calyxes will have a short stem (1 or 2 mm,) whereas a female will not. Two pistils will protrude from the single calyxes on each side of the nodes.
