What is infertility?

Infertility is defined as an inability to get pregnant after one year of trying, or, six months, for a woman who is 35 years of age or older. Women who can get pregnant but are unable to stay pregnant may also be infertile.

Pregnancy is the result of a process that has many steps. To get pregnant :

• A woman’s body must release an egg from one of her ovaries (ovulation).
• The egg must go through a fallopian tube toward the uterus (womb).
• A man’s sperm must join with (fertilize) the egg along the way.
• The fertilized egg must attach to the inside of the uterus (implantation).

Infertility can happen if there are problems with any of these steps.

Is infertility a common problem?

Yes. About 1 in six couples experiences infertility.

Is infertility just a woman’s problem?

No, infertility is not always a woman’s problem. Both women and men can have problems that cause infertility. About one-third of infertility cases are caused by women’s problems. Another third of fertility problems are attributed to male factors. The remaining cases are caused by a mixture of male and female problems or by unknown problems.

What causes infertility in men?

Infertility in men is most often caused by:

• A problem called varicocele (VAIR-ih-koh-seel). This happens when the veins on a man’s testicle(s) are too large. This heats the testicles. The heat can affect the number or shape of the sperm.
• Low sperm count.
• Lack of sperm mobility. This may be caused by the shape of the sperm. Sometimes injuries or other damage to the reproductive system block the sperm.

Sometimes a man is born with the problems that affect his sperm. Other times problems start later in life due to illness or injury. For example, cystic fibrosis often causes infertility in men.

What increases a man’s risk of infertility?

Factors that increase a man’s risk of infertility include:

• Alcohol use
• Drugs
• Smoking
• Age
• Environmental toxins, including pesticides and lead
• Health problems such as mumps, serious conditions like kidney disease, or hormone problems
• Medicines
• Radiation treatment and chemotherapy for cancer

What causes infertility in women?

Most cases of female infertility are caused by problems with ovulation. Without ovulation, there are no eggs to be fertilized. One sign that a woman is not ovulating normally is irregular or absent menstrual periods.

Ovulation problems are often caused by polycystic ovarian syndrome (PCOS). PCOS is a hormone imbalance problem which can interfere with normal ovulation. PCOS is the most common cause of female infertility. Primary ovarian insufficiency (POI) is another cause of ovulation problems. POI occurs when a woman’s ovaries stop working normally before she is 40. POI is not the same as early menopause.

Less common causes of fertility problems in women include:

• Blocked fallopian tubes due to pelvic inflammatory disease, endometriosis, or surgery for an ectopic pregnancy
• Physical problems with the uterus
• Uterine fibroids, which are non-cancerous clumps of tissue and muscle on the walls of the uterus

What increases a woman’s risk of infertility?

Many factors can change a woman’s ability to have a baby. These include:

• Age
• Smoking
• Excessive alcohol use
• Stress
• Poor diet
• Athletic training
• Being overweight or underweight
• Health problems that cause hormonal changes, such as polycystic ovarian syndrome and primary ovarian insufficiency

How does age affect a woman’s ability to have children?

Aging decreases a woman’s chances of having a baby in the following ways:

• Her ovaries become less able to release eggs
• The number of eggs decrease with age
• The health of the eggs decrease with age
• She is more likely to have health conditions that can cause fertility problems
• She is more likely to have a miscarriage

How long should women try to get pregnant before calling their doctors?

Most experts suggest that women should try for at least one year. Women aged 35 years or older should see their doctors after six months of trying. A woman’s chances of having a baby decrease rapidly every year after the age of 30.

Some health problems also increase the risk of infertility. So, women should talk to their doctors if they have:

• Irregular or no menstrual periods
• Very painful periods
• Endometriosis
• Pelvic inflammatory disease
• More than one miscarriage

It is a good idea for any woman to talk to a doctor before trying to get pregnant. Doctors can help you get your body ready for a healthy baby. They can also answer questions about fertility and give tips on conceiving.

At what time of the month is a woman most fertile?

The day you start your menstrual period is “Day1.” Around “Day 14” you may ovulate and release an egg. The egg is viable for 24 hours; this is your most fertile time. However, not all women ovulate on “Day 14.” Some ovulate earlier and some later. Some women do not ovulate at all. Your ovulation pattern can vary month to month. Even if you are getting your period, that does not mean you are ovulating. Read more about Ovulation here.

How can a woman tell when she ovulates?

One way of determining when you ovulate is to take your basal body temperature every morning and record it on a chart. Three or four months should be adequate to share with your doctor. You can also buy an ovulation predictor kit.

How will doctors find out if a couple has fertility problems: and where the problems lie?

Doctors will do an infertility checkup. This involves a physical exam. The doctor will also ask about both partners’ health. Sometimes this can reveal the problem. However, most of the time, the doctor will need to do more tests.

In men, doctors usually begin testing the sperm. They look at the number, shape, and movement of the sperm. Sometimes doctors also suggest testing the level of a man’s hormones.

In women, the first step is to find out if she is ovulating each month. There are a few ways to do this. A woman can track her ovulation at home by:

• Writing down changes in her morning body temperature for several months
• Writing down how her cervical mucus looks for several months
• Using a home ovulation test kit (available at drug or grocery stores)

Doctors can also check ovulation with blood tests. Or they can do an ultrasound of the ovaries. If ovulation is normal, there are other fertility tests available.

Some common tests of fertility in women include:

• Hysterosalpingography (HIS-tur-oh-sal-ping-GOGH-ru-fee): This is an X-ray of the uterus and fallopian tubes. Doctors inject a special dye into the uterus through the vagina. This dye shows up in the X-ray. Doctors can then watch to see if the dye moves freely through the uterus and fallopian tubes. This can help them find physical blocks that may be causing infertility. Blocks in the system can keep the egg from moving from the fallopian tube to the uterus. A block could also keep the sperm from reaching the egg.
• Laparoscopy (lap-uh-ROS-kuh-pee): A minor surgery to see inside the abdomen. The doctor does this with a small tool with a light called a laparoscope (LAP-uh-roh-skohp). She or he makes a small cut in the lower abdomen and inserts the laparoscope. With the laparoscope, the doctor can check the ovaries, fallopian tubes, and uterus for disease and physical problems. Doctors can usually find scarring and endometriosis by laparoscopy.

Finding the cause of infertility can be a long and emotional process. It may take time to complete all the needed tests. So don’t worry if the problem is not found right away.

How do doctors treat infertility?

Infertility can be treated with medicine, surgery, artificial insemination, or assisted reproductive technology. Many times these treatments are combined. In most cases infertility is treated with drugs or surgery.

Doctors recommend specific treatments for infertility based on:

• Test results
• How long the couple has been trying to get pregnant
• The age of both the man and woman
• The overall health of the partners
• Preference of the partners

Doctors often treat infertility in men in the following ways:

• Too few sperm: Sometimes surgery can correct the cause of the problem. In other cases, doctors surgically remove sperm directly from the male reproductive tract. Antibiotics can also be used to clear up infections affecting sperm count.
• Sperm movement: Sometimes semen has no sperm because of a block in the man’s system. In some cases, surgery can correct the problem.

In women, some physical problems can also be corrected with surgery. A number of fertility medicines are used to treat women with ovulation problems. It is important to talk with your doctor about the pros and cons of these medicines. You should understand the possible dangers, benefits, and side effects.

What medicines are used to treat infertility in women?

Some common medicines used to treat infertility in women include:

• Clomiphene citrate (Clomid®): This medicine causes ovulation by acting on the pituitary gland. It is often used in women who have polycystic ovarian syndrome (PCOS) or other problems with ovulation. This medicine is taken by mouth.
• Human menopausal gonadotropin or hMG (Repronex®, Pergonal®): This medicine is often used for women who don’t ovulate due to problems with their pituitary gland-hMG acts directly on the ovaries to stimulate ovulation. It is an injected medicine.
• Follicle-stimulating hormone or FSH (Gonal-F®, Follistim®): FSH works much like hMG. It causes the ovaries to begin the process of ovulation. These medicines are usually injected.
• Gonadotropin-releasing hormone (Gn-RH) analog: These medicines are often used for women who don’t ovulate regularly each month. Women who ovulate before the egg is ready can also use these medicines. Gn-RH analogs act on the pituitary gland to change when the body ovulates. These medicines are usually injected or given with a nasal spray.
• Metformin (Glucophage®): Doctors use this medicine for women who have insulin resistance and/or PCOS. This drug helps lower the high levels of male hormones in women with these conditions. This helps the body to ovulate. Sometimes clomiphene citrate or FSH is combined with metformin. This medicine is usually taken by mouth.
• Bromocriptine (Parlodel®): This medicine is used for women with ovulation problems due to high levels of prolactin. Prolactin is a hormone that causes milk production.

Many fertility drugs increase a woman’s chance of having twins, triplets, or other multiples. Women who are pregnant with multiple fetuses have more problems during pregnancy. Multiple fetuses have a high risk of being born too early (prematurely). Premature babies are at a higher risk of health and developmental problems.

What is intrauterine insemination (IUI)?

Intrauterine insemination (IUI) is an infertility treatment that is often called artificial insemination. In this procedure, the woman is injected with her husband’s washed sperm. Sometimes the woman is also treated with medicines that stimulate ovulation before IUI.
IUI is often used to treat:

• Mild male factor infertility
• Women who have problems with their cervical mucus
• Couples with unexplained infertility

What is assisted reproductive technology (ART)?

Assisted reproductive technology (ART) is a group of different methods used to help infertile couples. ART works by removing eggs from a woman’s body. The eggs are then mixed with sperm to make embryos. The embryos are then put back in the woman’s body.

How often is assisted reproductive technology (ART) successful?

Success rates vary and depend on many factors. Some things that affect the success rate of ART include:

• Age of the partners
• Reason for infertility
• Clinic
• Type of ART
• If the egg is fresh or frozen
• If the embryo is fresh or frozen

ART can be expensive and time-consuming. But it has allowed many couples to have children that otherwise would not have been conceived. The most common complication of ART is multiple fetuses. But this is a problem that can be prevented or minimized in several different ways.

What are the different types of assisted reproductive technology (ART)?

Common methods of ART include:

• In vitro fertilization (IVF) means fertilization outside of the body. IVF is the most effective ART. It is often used when a woman’s fallopian tubes are blocked or when a man produces too few sperm. Doctors treat the woman with a drug that causes the ovaries to produce multiple eggs. Once mature, the eggs are removed from the woman. They are put in a dish in the lab along with the man’s sperm for fertilization. After 3 to 5 days, healthy embryos are implanted in the woman’s uterus.
• Intracytoplasmic sperm injection (ICSI) is often used for couples in which there are serious problems with the sperm. Sometimes it is also used for older couples or for those with failed IVF attempts. In ICSI, a single sperm is injected into a mature egg. Then the embryo is transferred to the uterus or fallopian tube.
