  Hi @freyapigott
  Drinking and smoking before you’re fully developed has slightly different effects than doing so when you’re an adult. But I think that these activities will lower a man’s sperm count no matter what age he is. Smoking can certainly make men impotent.
  
  Hope this answers your question.
