HCG will increase your sperm count. Clomid will also. As far as Nolvadex on its own, I don't have any experience. HCG brought up my sperm count, but not to acceptable levels. Clomid really made a difference. To be honest, you'd have to check with a specialist on that one. You'd be surprised how many different things can have an impact on sperm production, and, just like trt, I don't think there is a one size fits all approach to it.
