Your plant is late into veg. Its trying to move into the next phase.
1 ball with no hairs, is something that happens in late veg. As you move into the flip, you'll see hairs (stigmata) come from there. If you don't, and a cluster of balls develop (unlikely) you can remove. You can remove now. But, there's no need. Even if it were early signs of male sac, not until you're in the heights of pre flower are they dangerous to your plant, seed wise.
1 ball : clit
2balls : ball sac
