Definition

Infertility is not being able to conceive after a year of trying. This means having regular, unprotected sex. About one-third of cases are caused by male factors. An equal number are caused by female factors. In the remaining cases, the cause is unknown or is due to problems with both partners.

Causes    TOP

Successful conception involves many steps:

• An egg is released from the woman's ovaries (ovulation).
• The egg travels to the fallopian tubes. Here the man's sperm can fertilize it.
• If the egg is fertilized (conception), it moves down the fallopian tubes to the uterus.
• It implants itself into the wall of the uterus. It then begins its 40 weeks of fetal growth.

Most cases of infertility are due to problems with ovulation or problems with fallopian tubes.

Symptoms    TOP

After one year of trying to conceive, you and your partner should seek help.

Diagnosis    TOP

During the first visit, you will both be evaluated. The doctor will ask about symptoms and medical history. Your doctor will look for physical problems that might cause infertility.

The following tests may be done to see if you are ovulating:

• Basal body temperature—rises at ovulation and remains elevated during the second half of your cycle and throughout pregnancy; you take your temperature every day and record it on a chart
• Blood test—to measure hormone levels
• Endometrial biopsy—to see if ovulation is causing changes in the lining of the uterus

The following may be done to check if your uterus and fallopian tubes are normal:

• Hysterosalpingography (HSG)—an x-ray of the uterus and fallopian tubes
• Transvaginal ultrasound—a device inserted into the vagina to take a "picture" of the pelvic organs
• Hysteroscopy—a thin device inserted through the cervix to look inside the uterus
• Laparoscopy—a small device with a camera is inserted into incisions in the abdomen, allowing the doctor to examine the fallopian tubes, ovaries, and uterus

Treatment    TOP

Treatment depends on what is causing the condition. Treatments can be costly and lengthy. They often are not covered by insurance.

Prevention    TOP

Not all causes of infertility can be prevented. The following steps may help:

• Stop smoking.
• Limit or avoid caffeine and alcohol.
• Maintain a healthy body weight.
• Protect yourself from sexually transmitted diseases (STDs) by using condoms. Minimize the number of sexual partners you have.
• Try stress management techniques.
