One on left is definitely a male sorry. Unless you want pollinated plants (which isn't a bad thing, just think about how many seeds you'll get and be able to grow) you'll just have to cut it down. But just because your plant becomes pollinated does not mean it will not be potent. Honestly I'd keep it and just grow the seeds if you get any females.

edit: Now that I look close the one on the right looks like a female if I'm correct. I think I see a pistil pointing up on the internode near the top.
