Is it possible to reduce sperm count if so how?

I was into the habit of masturbating about thrice a week since the last year and it is only 3 months back that i decided to reduce it to about once in 2 weeks as i felt it affected my symmetry and also did not have that 'octane' in my daily activities... But i have been unsuccessful to reduce it more than once a week as i get wet dreams when i don't do it beyond that period... So i get this question if it is possible to reduce my sperm count where i can do it once in 2 weeks... All suggestions are welcome
