Recreational Drugs

Abstract

Infertility affects roughly 15% of couples attempting to conceive. Male factor infertility affects approximately 7% of men and is the underlying cause in at least half of infertility cases. Recent large population studies evaluating semen parameters have highlighted alarming evidence of decreasing sperm concentration among modern societies. Increased interest in determining what lifestyle factors play a role in male infertility development has focused on modifiable risk factors. Recreational drugs such as cigarette smoke, alcohol, marijuana, methamphetamine/ecstasy, and cocaine have varying effects on male reproductive health. This chapter will review such modifiable risk factors and aid in appropriate counseling of reproductive aged males.
