Infertility is defined as a disease by the World Health Organization (WHO).
Frequent, unprotected intercourse results in conception for 50% of couples within 3 months, for 75% within 6 months, and for 90% within 1 year.
Infertility can be caused by the following:
Ovulatory dysfunction Ovulatory Dysfunction Ovulatory dysfunction is abnormal, irregular (with ≤ 9 menses/year), or absent ovulation. Menses are often irregular or absent. Diagnosis is often possible by menstrual history or can be confirmed... read more or (less frequently) decreased ovarian reserve Decreased Ovarian Reserve (DOR) Decreased ovarian reserve is a decrease in the quantity or quality of oocytes, leading to impaired fertility.

Tubal dysfunction and pelvic abnormalities Tubal Dysfunction and Pelvic Abnormalities Tubal dysfunction is fallopian tube obstruction or epithelial dysfunction that impairs oocyte, zygote, and/or sperm motility; pelvic structural abnormalities can impede fertilization or implantation... read more (about 30%)
Inability to conceive often leads to feelings of anxiety, sadness, frustration, anger, guilt, resentment, and inadequacy.
Couples wishing to conceive are encouraged to have frequent intercourse when conception is most likely—during the 6 days, and particularly the 3 days, before ovulation. Ovulation is most likely to occur about 14 days before the onset of the next menstrual period.
Measuring morning basal body temperature (BBT) daily can help determine when ovulation is occurring in women with regular menstrual cycles. A decrease suggests impending ovulation; an increase of ≥ 0.5° C suggests ovulation has just occurred. However, commercially available luteinizing hormone (LH) prediction test kits, which identify the midcycle LH surge, are probably the best way for women to determine when ovulation occurs and are less time-consuming than measuring BBT. BBT can be useful if women cannot afford or do not have access to LH prediction kits. There is no evidence that any test determining when ovulation occurs improves the likelihood of pregnancy in couples having regular intercourse.
Excessive use of caffeine, tobacco, or alcohol, which can impair fertility, is discouraged.
Evidence that men > 45 are less fertile than younger men, regardless of their female partner's age, is increasing.
Although infertility does not encompass recurrent miscarriages (spontaneous abortion Spontaneous Abortion Spontaneous abortion is pregnancy loss before 20 weeks gestation. Diagnosis is by pelvic examination, measurement of beta subunit of human chorionic gonadotropin, and ultrasonography. Treatment... read more ), the consequences are the same.
Evaluation of Infertility
Tests depending on the suspected cause
(See also American College of Obstetricians and Gynecologists’ Committee on Gynecologic Practice's and American Society for Reproductive Medicine's Infertility Workup for the Women’s Health Specialist.)
If attempts to achieve pregnancy do not result in pregnancy after ≥ 1 year, both partners are evaluated. Evaluation begins with history, examination, and counseling. Men are evaluated for sperm disorders, and women are evaluated for ovulatory and tubal dysfunction and pelvic pathology.
Evaluation is done sooner than 1 year if
The woman is > 35 years old.
The woman is known to have decreased ovarian reserve (eg, because she has only one ovary).
The woman has infrequent menses.
The woman has a known abnormality of the uterus, fallopian tubes, or ovaries.
The man is known to be subfertile or is at risk of subfertility.
Tests are done depending on the suspected cause (eg, for decreased ovarian reserve, measurement of follicle-stimulating hormone and antimüllerian hormone and antral follicle count, determined by transvaginal ultrasonography; for sperm disorders, semen analysis).
Treatment of Infertility
Treatment of the primary cause
Sometimes medications to induce ovulation or spermatogenesis
Sometimes assisted reproductive techniques
The primary cause of male or female infertility is treated, if possible. For example, structural abnormalities of the reproductive tract (eg, testicular varicocele, uterine leiomyomas) or endocrine abnormalities (eg, pituitary adenoma, thyroid disorders) can be treated. Patients should be encouraged to make changes to minimize modifiable risk factors. For example, smoking cessation for smokers, weight loss for overweight patients, no or moderate consumption of alcohol, and consumption of a balanced diet (with vitamins if needed) are recommended.
In general, treatment is directed at improving the likelihood of conception by increasing the availability of high-quality oocytes (eg, ovulation induction, egg donation) or sperm (eg, gonadotropin medications to induce spermatogenesis, sperm donation) and by using procedures to assist contact between the oocyte and sperm to achieve fertilization (eg, intrauterine insemination, in vitro fertilization).
People with infertility may experience sadness, anxiety, frustration, emotional stress, feelings of inadequacy, guilt, or anger. These feelings can lead to sleep or eating disturbances or clinical anxiety or depression. Counseling and behavioral health support should be offered if needed.
Giving both partners information about the treatment process is helpful. Such information includes
What the chances of success are
What the process involves, including time and costs
When to end treatment
When to consider adoption
