In brief: Many things

Sperm production is inhibited by high temperature (sauna, lap top on thighs), stress, varicoceles, and testosterone supplements (by indirect suppression of testicular function).
Some men have genetic mutation in the y chromosome that impairs sperm production. Sperm motility is another critical factor in determining male fertility. A semen analysis can check both sperm count and motility.

In brief: Mainly physiology

Studies on lifestyle items including stress, seem to have only a 10 % effect on a man's baseline fertility.
Genetics, anatomic, physiologic and hormonal issues appear to be the main factors influencing male fertility.
