Infertility is defined as trying to get pregnant (with frequent intercourse) for at least a year with no success. Female infertility, male infertility or a combination of the two affects millions of couples in the United States. An estimated 10 to 18 percent of couples have trouble getting pregnant or having a successful delivery.

Infertility results from female factors about one-third of the time and male factors about one-third of the time. The cause is either unknown or a combination of male and female factors in the remaining cases.

Female infertility causes can be difficult to diagnose. There are many available treatments, which will depend on the cause of infertility. Many infertile couples will go on to conceive a child without treatment. After trying to get pregnant for two years, about 95 percent of couples successfully conceive.

Symptoms

The main symptom of infertility is the inability to get pregnant. A menstrual cycle that's too long (35 days or more), too short (less than 21 days), irregular or absent can mean that you're not ovulating. There may be no other outward signs or symptoms.

When to see a doctor

When to seek help sometimes depends on your age:

• Up to age 35, most doctors recommend trying to get pregnant for at least a year before testing or treatment.
• If you're between 35 and 40, discuss your concerns with your doctor after six months of trying.
• If you're older than 40, your doctor may want to begin testing or treatment right away.

Your doctor may also want to begin testing or treatment right away if you or your partner has known fertility problems, or if you have a history of irregular or painful periods, pelvic inflammatory disease, repeated miscarriages, prior cancer treatment, or endometriosis.

Causes

Each of these factors is essential to become pregnant:

• You need to ovulate. To get pregnant, your ovaries must produce and release an egg, a process known as ovulation. Your doctor can help evaluate your menstrual cycles and confirm ovulation.
• Your partner needs sperm. For most couples, this isn't a problem unless your partner has a history of illness or surgery. Your doctor can run some simple tests to evaluate the health of your partner's sperm.
• You need to have regular intercourse. You need to have regular sexual intercourse during your fertile time. Your doctor can help you better understand when you're most fertile.
• You need to have open fallopian tubes and a normal uterus. The egg and sperm meet in the fallopian tubes, and the embryo needs a healthy uterus in which to grow.

Prevention

For women thinking about getting pregnant soon or in the future, these tips may help optimize fertility:

• Maintain a normal weight. Overweight and underweight women are at increased risk of ovulation disorders. If you need to lose weight, exercise moderately. Strenuous, intense exercise of more than five hours a week has been associated with decreased ovulation.
• Quit smoking. Tobacco has multiple negative effects on fertility, not to mention your general health and the health of a fetus. If you smoke and are considering pregnancy, quit now.
• Avoid alcohol. Heavy alcohol use may lead to decreased fertility. And any alcohol use can affect the health of a developing fetus. If you're planning to become pregnant, avoid alcohol, and don't drink alcohol while you're pregnant.
• Reduce stress. Some studies have shown that couples experiencing psychological stress had poorer results with infertility treatment. If you can, find a way to reduce stress in your life before trying to become pregnant.
• Limit caffeine. Research suggests that limiting caffeine intake to less than 200 milligrams a day shouldn't affect your ability to get pregnant. That's about one to two cups of 6 to 8 ounces of coffee per day.
