In general, infertility is defined as not being able to get pregnant (conceive) after one year (or longer) of unprotected sex. Because fertility in women is known to decline steadily with age, some providers evaluate and treat women aged 35 years or older after 6 months of unprotected sex. Women with infertility should consider making an appointment with a reproductive endocrinologist—a doctor who specializes in managing infertility. Reproductive endocrinologists may also be able to help women with recurrent pregnancy loss, defined as having two or more spontaneous miscarriages.

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 ).
A man’s sperm must join with the egg along the way (fertilize).
The fertilized egg must go through a fallopian tube toward the uterus (womb).
The fertilized egg must attach to the inside of the uterus (implantation).

Infertility may result from a problem with any or several of these steps.

Impaired fecundity is a condition related to infertility and refers to women who have difficulty getting pregnant or carrying a pregnancy to term.

Infertility FAQs

Is infertility a common problem?

Yes. About 6% of married women aged 15 to 44 years in the United States are unable to get pregnant after one year of trying (infertility). Also, about 12% of women aged 15 to 44 years in the United States have difficulty getting pregnant or carrying a pregnancy to term, regardless of marital status (impaired fecundity).

Is infertility just a woman's problem?

No, infertility is not always a woman’s problem. Both men and women can contribute to infertility.

Many couples struggle with infertility and seek help to become pregnant, but it is often thought of as only a woman’s condition. However, in about 35% of couples with infertility, a male factor is identified along with a female factor. In about 8% of couples with infertility, a male factor is the only identifiable cause.

Almost 9% of men aged 25 to 44 years in the United States reported that they or their partner saw a doctor for advice, testing, or treatment for infertility during their lifetime.

What causes infertility in men?

collapsed

Infertility in men can be caused by different factors and is typically evaluated by a semen analysis. When a semen analysis is performed, the number of sperm (concentration), motility (movement), and morphology (shape) are assessed by a specialist. A slightly abnormal semen analysis does not mean that a man is necessarily infertile. Instead, a semen analysis helps determine if and how male factors are contributing to infertility.

Disruption of testicular or ejaculatory function

Varicoceles, a condition in which the veins on a man’s testicles are large and cause them to overheat. The heat may affect the number or shape of the sperm.

Trauma to the testes may affect sperm production and result in lower number of sperm.

Unhealthy habits such as heavy alcohol use, smoking, anabolic steroid use, and illicit drug use.

Use of certain medications and supplements.

Cancer treatment involving the use of certain types of chemotherapy, radiation, or surgery to remove one or both testicles

Medical conditions such as diabetes, cystic fibrosis, certain types of autoimmune disorders, and certain types of infections may cause testicular failure.

Hormonal disorders

Improper function of the hypothalamus or pituitary glands. The hypothalamus and pituitary glands in the brain produce hormones that maintain normal testicular function. Production of too much prolactin, a hormone made by the pituitary gland (often due to the presence of a benign pituitary gland tumor), or other conditions that damage or impair the function of the hypothalamus or the pituitary gland may result in low or no sperm production.

These conditions may include benign and malignant (cancerous) pituitary tumors, congenital adrenal hyperplasia, exposure to too much estrogen, exposure to too much testosterone, Cushing’s syndrome, and chronic use of medications called glucocorticoids.

Genetic disorders

Genetic conditions such as a Klinefelter’s syndrome, Y-chromosome microdeletion, myotonic dystrophy, and other, less common genetic disorders may cause no sperm to be produced, or low numbers of sperm to be produced.

What increases a man’s risk of infertility?

Age. Although advanced age plays a much more important role in predicting female infertility, couples in which the male partner is 40 years old or older are more likely to report difficulty conceiving.

Being overweight or obese.

Smoking.

Excessive alcohol use.

Use of marijuana.

Exposure to testosterone. This may occur when a doctor prescribes testosterone injections, implants, or topical gel for low testosterone, or when a man takes testosterone or similar medications illicitly for the purposes of increasing their muscle mass.

Exposure to radiation.

Frequent exposure of the testes to high temperatures, such as that which may occur in men confined to a wheelchair, or through frequent sauna or hot tub use.

Exposure to certain medications such as flutamide, cyproterone, bicalutamide, spironolactone, ketoconazole, or cimetidine.

Exposure to environmental toxins including exposure to pesticides, lead, cadmium, or mercury.

What causes infertility in women? collapsed

Women need functioning ovaries , fallopian tubes , and a uterus to get pregnant. Conditions affecting any one of these organs can contribute to female infertility. Some of these conditions are listed below and can be evaluated using a number of different tests.

Disruption of ovarian function (presence or absence of ovulation (anovulation) and effects of ovarian “age”)

A woman’s menstrual cycle is, on average, 28 days long. Day 1 is defined as the first day of “full flow.” Regular predictable periods that occur every 24 to 32 days likely reflect ovulation. A woman with irregular periods is likely not ovulating.

Ovulation can be predicted by using an ovulation predictor kit and can be confirmed by a blood test to check the woman’s progesterone level on day 21 of her menstrual cycle. Although several tests exist to evaluate a woman’s ovarian function, no single test is a perfect predictor of fertility. The most commonly used markers of ovarian function include follicle stimulating hormone (FSH) value on day 3 to 5 of the menstrual cycle, anti-müllerian hormone value (AMH), and antral follicle count (AFC) using a transvaginal ultrasound.

Disruptions in ovarian function may be caused by several conditions and warrants an evaluation by a doctor.

When a woman doesn’t ovulate during a menstrual cycle, it’s called anovulation. Potential causes of anovulation include the following

Polycystic ovary syndrome (PCOS). PCOS is a condition that causes women to not ovulate, or to ovulate irregularly. Some women with PCOS have elevated levels of testosterone, which can cause acne and excess hair growth. PCOS is the most common cause of female infertility.

Diminished ovarian reserve (DOR). Women are born with all of the eggs that they will ever have, and a woman’s egg count decreases over time. Diminished ovarian reserve is a condition in which there are fewer eggs remaining in the ovaries than normal. The number of eggs a woman has declines naturally as a woman ages. It may also occur due to congenital, medical, surgical, or unexplained causes. Women with diminished ovarian reserve may be able to conceive naturally, but will produce fewer eggs in response to fertility treatments.

Functional hypothalamic amenorrhea (FHA). FHA is a condition caused by excessive exercise, stress, or low body weight. It is sometimes associated with eating disorders such as anorexia.

Improper function of the hypothalamus and pituitary glands. The hypothalamus and pituitary glands in the brain produce hormones that maintain normal ovarian function. Production of too much of the hormone prolactin by the pituitary gland (often as the result of a benign pituitary gland tumor), or improper function of the hypothalamus or pituitary gland, may cause a woman not to ovulate.

Premature ovarian insufficiency (POI). POI, sometimes referred to as premature menopause, occurs when a woman’s ovaries fail before she is 40 years of age. Although certain exposures, such as chemotherapy or pelvic radiation therapy, and certain medical conditions may cause POI, the cause is often unexplained. About 5% to10% of women with POI conceive naturally and have a normal pregnancy.

Menopause Menopause is an age-appropriate decline in ovarian function that usually occurs around age 50. By definition, a woman in menopause has not had a period in one year. She may experience hot flashes, mood changes, difficulty sleeping, and other symptoms as well.

Fallopian tube obstruction (whether fallopian tubes are open, blocked, or swollen)

Risk factors for blocked fallopian tubes (tubal occlusion) can include a history of pelvic infection, history of ruptured appendicitis, history of gonorrhea or chlamydia, known endometriosis , or a history of abdominal surgery.

Tubal evaluation may be performed using an X-ray that is called a hysterosalpingogram (HSG), or by chromopertubation (CP) in the operating room at time of laparoscopy, a surgical procedure in which a small incision is made and a viewing tube called a laparoscope is inserted.

Hysterosalpingogram (HSG) is an X-ray of the uterus and fallopian tubes. A radiologist injects dye into the uterus through the cervix and simultaneously takes X-ray pictures to see if the dye moves freely through fallopian tubes. This helps evaluate tubal caliber (diameter) and patency.

Chromopertubation is similar to an HSG but is done in the operating room at the time of a laparoscopy. Blue-colored dye is passed through the cervix into the uterus and spillage and tubal caliber (shape) is evaluated.

Abnormal uterine contour (physical characteristics of the uterus)

Depending on a woman’s symptoms, the uterus may be evaluated by transvaginal ultrasound to look for fibroids or other anatomic abnormalities. If suspicion exists that the fibroids may be entering the endometrial cavity, a sonohystogram (SHG) or hysteroscopy (HSC) may be performed to further evaluate the uterine environment.

What increases a woman's risk of infertility?

collapsedFemale fertility is known to decline with

Age. More women are waiting until their 30s and 40s to have children. In fact, about 20% of women in the United States now have their first child after age 35. About one-third of couples in which the woman is older than 35 years have fertility problems. Aging not only decreases a woman’s chances of having a baby, but also increases her chances of miscarriage and of having a child with a genetic abnormality.

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

She has a smaller number of eggs left.

Her eggs are not as healthy.

She is more likely to have health conditions that can cause fertility problems.

She is more likely to have a miscarriage.

Smoking.

Excessive alcohol use.

Extreme weight gain or loss.

Excessive physical or emotional stress that results in amenorrhea (absent periods).
