Marijuana may disrupt a woman's ovulation cycle, affecting the release of the egg. In men, marijuana use can decrease the sperm count as well as affect the quality of the sperm.
Heroin, cocaine, and crack cocaine use induces similar effects but places the user at increased risk for PID and HIV infection associated with risky sexual behavior.
