If you are trying to become pregnant it might be a good idea to take a close look at your lifestyle. Certain lifestyle factors can interfere with a couple's ability to conceive. Environmental hazards, dietary practices, and poor overall health tend to have a negative influence on both female and male fertility. Sometimes, simple changes to your lifestyle can help to increase your fertility and help you to conceive.

Alcohol and Infertility
Most of us know by now that alcohol and pregnancy just don't mix. Alcohol consumption is not recommended at all during pregnancy, and for good reason - it can cause serious birth defects and may trigger fetal alcohol syndrome. When you are trying to conceive, it is also important to limit your alcohol consumption or cut out those alcoholic beverages altogether. Alcohol can have detrimental effects on your fertility, making it more difficult to become pregnant.

Women who drink between one and five alcoholic drinks a week are actually associated with decreased conception rates. Women who regularly drink alcohol are also at increased risk for experiencing:
irregular periods
irregularities in ovulation
early menopause
miscarriage

Men who regularly drink alcohol are also at risk for experiencing fertility problems, including:
reduced testosterone levels
reduced sex drive
problems with sperm motility and morphology
 
Cigarette Smoking
Cigarette smoking can be a tough habit to quit, but if you are trying to become pregnant, now is a great time. Smoking is a big no-no during pregnancy anyways, and it can also impact negatively on your fertility. Female smokers are three to four times more likely to have problems getting pregnant. They are also at increased risk for:
menstrual irregularities
tubal factor infertility
implantation problems

Men who are smokers are also compromising their fertility. Male smokers increase their risk for:
erectile dysfunction
chromosomal abnormalities within their sperm
There are a variety of aids available to help you quit smoking. From gum to patches to botanical supplements, these aids have made butting out easier than ever.

Environmental Hazards
Sometimes the enviroment around you can actually interfere with your ability to become pregnant. Toxic fumes, lead, and other poisons can cause serious fertility problems, especially if you are exposed to them on a daily basis. Try to avoid:

pesticides
herbicides
fungicides
paint fumes
radiation
chemical cleaners or solvents
