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 history or can be confirmed by... 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.

Inability to conceive often leads to feelings of 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 disruptive 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 and tobacco, 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.

If attempts to achieve pregnancy do not result in pregnancy after ≥ 1 years, 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 lesions.
Evaluation is done sooner than 1 year if
Tests are done depending on the suspected cause (eg, for decreased ovarian reserve, measurement of follicle-stimulating hormone, estradiol, antimüllerian hormone, and antral follicle count, determined by transvaginal ultrasonography; for sperm disorders, semen analysis).
A couple who is being treated for infertility can experience frustration, emotional stress, feelings of inadequacy, guilt, anger, resentment, worry (eg, about finances). These feelings can lead to fatigue, anxiety, sleep or eating disturbances, and loss of concentration. Counseling and psychologic support should be offered if needed.
