Impaired fecundity is a condition related to infertility and refers to women who have difficulty getting pregnant or carrying a pregnancy to term.
Also, about 11% of women 15–44 years of age in the United States have difficulty getting pregnant or carrying a pregnancy to term, regardless of marital status (impaired fecundity).
No, infertility is not always a woman’s problem. Both men and women contribute to infertility.
Many couples struggle with infertility and seek help to become pregnant; however, it is often thought of as only a women’s condition. A CDC study analyzed data from the 2002 National Survey of Family Growth and found that 7.5% of all sexually experienced men younger than age 45 reported seeing a fertility doctor during their lifetime—this equals 3.3–4.7 million men. Of the men who sought help, 18% were diagnosed with a male-related infertility problem, including sperm or semen problems (14%) and varicocele (6%).
Conditions that can contribute to abnormal semen analyses include—
• Blockage (obstruction) of the male reproductive tract
• Hormonal factors affecting the formation and development of sperm
• Varicocele (an enlargement of the veins within the scrotum)
• Certain genetic diseases (i.e. cystic fibrosis)
• Exposure to environmental toxins and excessive heat
• Lifestyle factors (smoking, drinking, drug use, steroids, obesity),
• Cancer and other medical conditions and treatments
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.
Female fertility is known to decline with age. Many 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, and this leads to age becoming a growing cause of fertility problems. 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—
• Her ovaries become less able to release eggs.
• 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.
• Excessive alcohol use.
• Extreme weight gain or loss.
• Excessive physical or emotional stress that results in amenorrhea (absent periods).
Most experts suggest at least one year for women younger than age 35. However, women aged 35 years or older should see a health care provider after 6 months of trying unsuccessfully. 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 a health care provider if they have
• Irregular periods or no menstrual periods.
• Very painful periods.
• Pelvic inflammatory disease.
• More than one miscarriage.
It is a good idea for any woman and her partner to talk to a health care provider before trying to get pregnant. They can help a woman prepare her body for carrying a pregnancy and delivering a healthy baby, and can also answer questions on fertility and give tips on conceiving.
• The factors contributing to the infertility.
• The duration of the infertility.
• The age of the female.
• The couple’s treatment preference after counseling about success rates, risks, and benefits of each treatment option.
Some common medicines used to treat infertility in women include—
• Clomiphene citrate (Clomid®*): A medicine that 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®*): Medicine often used for women who don’t ovulate because of 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®*): Medicine that work much like hMG. It causes the ovaries to begin the process of ovulation. These medicines are usually injected.
• Gonadotropin-releasing hormone (Gn-RH): Medicine 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 that act on the pituitary gland to change when the body ovulates. These medicines are usually injected or given with a nasal spray.
• Metformin (Glucophage®*): A medicine doctors use 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®*): A medicine used for women with ovulation problems because of high levels of prolactin. Prolactin is a hormone that causes milk production.
Intrauterine insemination (IUI) is an infertility treatment that is often called artificial insemination. In this procedure, specially prepared sperm are inserted into the woman’s uterus. Sometimes the woman is also treated with medicine that stimulates ovulation before IUI.
According to the CDC’s 2011 Preliminary ART Success Rates, the average percentage of fresh, nondonor ART cycles that led to pregnancy were—
• 40% in women younger than 35 years of age.
• 32% in women aged 35–37 years.
• 22% in women aged 38–40 years.
• 12% in women aged 41–42 years.
• 5% in women aged 43–44 years.
• 1% in women aged 44 years and older.

• 75% in women younger than 35 years of age.
• 73% in women aged 35–37 years.
• 55% in women aged 38–40 years.
• 44% in women aged 41–42 years.*
• 50% in women aged 43–44 years.*
• Women using Donor Eggs: 58% fresh 68% frozen.
* 2 years combined (2011-2012)
• Intrauterine insemination (IUI) in which processed sperm is injected directly into the uterus by-passing the cervix. Insemination may be combined with ovarian stimulation to increase the chance of fertilization of one or more eggs occurring inside the fallopian tubes.
• In vitro fertilization (IVF), meaning fertilization outside of the body. IVF is one of the most commonly used techniques in which eggs are combined with sperm in a dish in a laboratory. Once fertilization has occurred, the resulting embryos develop for several days before being placed into the uterus.
• Intracytoplasmic sperm injection (ICSI) is often used for couples with male factor infertility, unexplained infertility or for those patients with failed conventional IVF attempts. In ICSI, a single sperm is injected into a mature egg with a microscopic needle. Once fertilization occurs, the embryos are grown for several days and then transferred into the uterus.
• Egg Donation is used for women with no eggs or unhealthy eggs. A young egg donor undergoes ovarian stimulation and an egg retrieval procedure to donate her eggs to another patient. The eggs are fertilized with the partner’s sperm and resultant embryos transferred to the patient’s uterus.
