It's not always easy to talk about, but 10 percent of couples that wish to have a baby are still unable to after a year of unprotected sex. About half of these couples can achieve pregnancy within two years after appropriate treatment of the woman, the man, or both, but it can require a lot more effort than charting out your ovulation days. There are no dietary or nutritional cures for infertility, but specialists stress that a healthy lifestyle is important. For a list of lifestyle changes that can help,
Maintain a healthy weight. Women who are either over- or underweight are at risk for fertility failure, including a lower chance for achieving success with fertility procedures. Everyone should have a diet rich in fresh fruits and vegetables and whole grains and low in saturated fats.
Stop smoking. Smoking increases the risk for infertility in both men and women, and poses a future health risk for the mother and infant. Everyone should quit.
Avoid caffeine and alcohol.
Avoid excessive exercise if it causes menstrual irregularity. However, moderate and regular exercise is essential for good health. Few women exercise to the extent that their periods are affected. For those who do, one study found that simply adding calories can restore menstruation in many cases.
Don't use electric blankets. In one study, a 74% higher incidence of spontaneous abortion was associated with using an electric blanket during the month of conception. There was no association with heated waterbeds or electromagnetic waves.
