What is infertility?
Infertility is usually defined as not being able to get
pregnant after trying for at least 1 year. Women who are
able to get pregnant but then have repeat miscarriages are
also said to be infertile. Infertility is a problem for 1
of every 6 couples. It can be caused by problems in a man's
or woman's reproductive system. Problems in the woman's
body are responsible for about half of the cases of
infertility.
How does it occur?
Often the reason a woman is infertile is that her ovaries
are not releasing eggs. For example, when a woman gets
older, the ability of the ovaries to produce and release
healthy eggs declines, especially after age 35. Other
things that may affect the eggs and the release of eggs
(ovulation) are:
- hormone problems
- overweight or underweight
- smoking
- too much stress
- unhealthy diet
- ovarian tumors or cysts
- intense exercise, such as long distance running, which
causes loss of body fat
- abuse of alcohol or drugs
- tumors in the pituitary gland
- chronic illness, such as diabetes, or other illness
- some medicines.
A woman who is not ovulating normally may have irregular or
missed menstrual periods.
An abnormal or damaged fallopian tube or uterus can be
another cause of infertility. When an egg is released, it
must pass through a fallopian tube to the uterus. A man's
sperm must join with (fertilize) the egg along the way. The
fertilized egg must then attach to the inside of the uterus.
A fallopian tube or the uterus may be damaged by:
- an infection, such as a sexually transmitted disease
- a birth defect in the female organs
- growths in the uterus, such as polyps or fibroids
- scar tissue from surgery (called adhesions)
- endometriosis (tissue from the uterus growing outside the
uterus)
- DES syndrome, which you may have if your mother took the
medicine DES when she was pregnant with you.
You may have problems with your cervix that make it hard
for the sperm to reach and fertilize the egg, such as:
- cervical stenosis (a cervix that is very narrow or
closed)
- abnormal cervical mucus
- cervicitis, which is inflammation or infection of the
cervix.
In rare cases, a woman's body is allergic to sperm and
destroys it.
Some rare genetic problems also cause infertility. Thirty
percent of infertility cases have no known cause.
How is it diagnosed?
You and your partner will have thorough physical exams. You
will be asked about:
- your sexual history, including previous pregnancy,
miscarriage, or abortion
- your medical and family history
- your diet and exercise habits
- stress
- your use of drugs, alcohol, and tobacco
- your sexual intercourse practices, such as how often you
have sex and whether you use lubricants.
You may need to find out if you are ovulating each month.
Your healthcare provider can tell you how to take and chart
your body temperature each morning. Your temperature will
rise after ovulation. You can buy kits at the drugstore
that can help predict ovulation. Blood tests and an
ultrasound of the ovaries can also be used to see if you are
ovulating.
Other tests that may be done are:
- urine and blood tests to check for infections and a
hormone imbalance
- tests of samples of cervical mucus and tissue from the
lining of your uterus
- tests of your partner's semen to check the number and
quality of sperm in the semen.
You may have the following procedures to check for a
blockage in your tubes or uterus, scar tissue, or
endometriosis:
- hysteroscopy (putting a scope into the vagina and through
the cervix to examine the inside of the uterus)
- laparoscopy (inserting a scope into your abdomen through
a small cut to examine the organs in your abdomen)
- hysterosalpingogram (X-ray of the uterus and fallopian
tubes after injection of a dye through the cervix and
into the uterus and fallopian tubes).
How is it treated?
Your provider will try to find the cause of the infertility
and, if a cause is found, treat the cause. The treatment
may include medicine (usually hormones or antibiotics) or
surgery. Sometimes a combination of treatments for both
partners is necessary. Examples of treatments for women
are:
- Taking hormones for a hormone imbalance, endometriosis,
or short menstrual cycle.
- Quitting smoking if you are a smoker.
- Stopping use of alcohol or drugs.
- Taking drugs to stimulate ovulation. (Sometimes with
this treatment you may become pregnant with more than 1
baby.)
- Having surgery to remove blockage or scar tissue from the
fallopian tubes, uterus, cervix, or pelvis.
- Having surgery to remove polyps or fibroids from the
uterus.
If your partner's sperm count is low, intrauterine
(artificial) insemination may be an option. Semen can be
collected at several different times and stored until there
are enough sperm. The semen is then placed in your uterus
or fallopian tubes during the most fertile time of your
menstrual cycle. Another choice is to use sperm donated by
another man.
Assisted reproductive technology (ART) is another option.
It involves several different methods for removing eggs from
your body, mixing the eggs with sperm in the lab, and
putting the fertilized eggs (embryos) back into your body.
The most effective ART is in vitro fertilization. It is
often done when a man's sperm count is low or your fallopian
tubes are blocked. ART can be expensive and time-consuming,
but it has made it possible for many couples to have
children.
About two-thirds of couples who are treated for infertility
are able to have a baby, but looking for and treating causes
of infertility can be stressful for a couple. It can put
unusual strain on your relationship. Counseling may help
you get through hard times.
How can I help prevent infertility?
You may not be able to prevent infertility resulting from
genetic problems or an illness. However, you can do the
following to reduce the risk of infertility:
- Prevent sexually transmitted diseases by using latex or
polyurethane condoms. Also, have just 1 sexual partner
who is not sexually active with anyone else.
- Limit the amount of alcohol you drink to no more than 1
or 2 drinks a week.
- Avoid the use of street drugs (such as heroin) and
overuse of prescription and nonprescription drugs.
- Do not smoke.
- Maintain good personal hygiene and health practices.
- Do not use lubricant during sexual intercourse because
it can make it harder for the sperm to reach the egg.
Contact your healthcare provider about any signs of
infection or hormonal change, such as:
- unusual discharge from the vagina
- abdominal pain or swelling
- fever
- abnormal bleeding
- a change in your menstrual periods
- discomfort during intercourse
- sores and itching in the vagina or rectal area.
