In brief: Not always

1/3 of infertility stems from "male factor." red flags in a man's history include mumps, fevers or a job environment with heat to the scrotum. Marijuana use lowers sperm count.
However, men may be born with no vas deferens and not be making sperm but ejaculating with what looks normal.
