Yeah, they're referred to as nanners in some instances. Left any later they develop flowers (not buds, literal flowers), the pollen sacs open ready for any females nearby to receive. The "balls" group together at node sites. Was this a mystery seed from a bag? Or purchased either way gutting to get to that stage and be male. Next time there will be earlier signs, at each node they develop tear shaped little preflowers, white pistils will emerge showing her female sex. Or alternatively football shaped balls that drop down and or group. Hope this helps.
