I started smoking around 6 months ago. At first I barely smoked. Then after a few months, I smoked more. I only smoked atleast a bowl a day, then slowed it down again. Over the course of these 6 months, my sperm’s density, thickness, and amount has gone up. I am an 18 year old, 6 foot 2, 200 pounds even. I don’t have much fat, and I do work out. Would you say that my sperm count going up is due to puberty (late stages) or possibly marijuana? I know it’s a stupid question, considering marijuana is known to reduce sperm count.
