In brief: Various
Commonly opioid substances, alcohol to name some as they inhibit CRF in the brain and decrease testosterone.
This in the process also causes decreased libido.

In brief: Cigarettes
The best data appears to be that cigarette smoke decreases sperm count and quality somewhat in men with known varicoceles (varicoces veins of the testicles).
Marijuana and alcohol have been suggested but in my clinical practice their effects are limited except at very high usage levels.
