Drug use

Anabolic steroids taken to stimulate muscle strength and growth can cause the testicles to shrink and sperm production to decrease. Use of cocaine or marijuana might reduce the number and quality of your sperm as well.

Poor lifestyle

Men who smoke might have a lower sperm count than those who don’t smoke.

Obesity can impair fertility in several ways, including directly impacting sperm and by causing hormone changes.
