lol.. those lomps at the base of the leaf are leaf nodes , ur plant is a female u can be sure of that , plant will turn hermie more likely from stress than anything else, a plant will even produce sum male flowers in a last dying act to pollenate itself towards the end of flowering. But take it from me thats a lady u have at the minute and unless shes turns into sum crazy PMT biatch and stresses herself to the max , she will remain that way.
ihope this helps
