Smoking can have the same effect on your sexual performance as having your mom walk in on you. Smoking in men has been linked to erectile dysfunction and lower-than-normal levels of the male sex hormone testosterone. Some studies have even found a connection between smoking and low sex drive.
If you are a woman, you aren't off the hook. Smoking can change the hormone levels in your body, leading to problems with your menstrual cycle, difficulty getting pregnant and an increased risk of miscarriage.
Your best bet for a better, healthier sex life: Stop smoking.
