But before undergoing any complicated procedures, there are some simple lifestyle changes that can better the odds of a successful conception. Stop smoking cigarettes or marijuana. Smoking tobacco has been linked to low sperm counts and sluggish motility. Long-term use of marijuana can result in low sperm count and abnormally developed sperm. Decrease your drinking.
Alcohol can reduce the production of normally formed sperm needed for a successful pregnancy.
Watch your weight. Both overweight and underweight men can have fertility problems. With too much weight, there can be hormonal disturbances, and when a man's too lean, he can have decreased sperm count and functionality. Exercise in moderation. Excessive exercise could lower your sperm count indirectly by lowering the amount of testosterone in your body.
