Frequent intercourse without birth control usually results in pregnancy:
For 50% of couples within 3 months
For 75% within 6 months
For 90% within 1 year
To maximize the chance of pregnancy, couples should have frequent intercourse in the 6 days—and particularly the 3 days—before the ovaries release an egg (ovulation). Ovulation usually occurs in the middle of the menstrual cycle, which is about 14 days before the first day of a women's next period.
Two of the more common methods women can use to estimate when ovulation occurs are
Measurement of body temperature at rest (basal body temperature)
Home ovulation predictor kits (probably the best way)
If women have regular periods, they can estimate when ovulation occurs by measuring their temperature each day before they get out of bed. A decrease suggests that ovulation is about to occur. An increase of 0.9° F (0.5° C) or more suggests ovulation has just occurred. However, this method is inconvenient for many women and is not reliable or precise. At best, it predicts ovulation only within 2 days.
Home ovulation prediction kits are more accurate. These kits are used to detect an increase in luteinizing hormone in the urine. (Luteinizing hormone stimulates the ovaries to stimulate ovulation.) Usually, this increase occurs 24 to 36 hours before ovulation. Women usually need to repeat the test for several consecutive days, so kits typically include five to seven sticks. The sticks can be held under a stream of urine or dipped into urine that is collected in a sterile container.
Whether estimating when ovulation will occur increases the chance of pregnancy for couple who have intercourse regularly is unknown. However, estimating when ovulation will occur is likely to help couples who do not have intercourse regularly estimate when the best time for intercourse is.
Up to one in five couples in the United States do not conceive for at least a year and are thus considered infertile. However, of the couples who have not conceived after a year of trying, more than 60% conceive eventually, with or without treatment.
Causes of Infertility
The cause of infertility may be due to problems in the man, the woman, or both:
Problems with the fallopian tubes and abnormalities in the pelvis Problems With the Fallopian Tubes and Abnormalities in the Pelvis The fallopian tube may be blocked or damaged, preventing the sperm from reaching the egg or preventing the egg or fertilized egg (zygote) from moving from the ovary to the uterus to be implanted... read more (in about 30%)
Consuming a lot of caffeine (for example, more than 5 to 6 cups of coffee per day), using excess tobacco, and/or drinking excess alcohol can impair fertility in women and should be avoided.
Diagnosis of Infertility
A doctor's evaluation
Various tests depending on the suspected cause
The diagnosis of infertility problems requires a thorough assessment of both partners. Usually, the assessment is done after at least 1 year of trying to achieve a pregnancy. However, it is done sooner if
The woman is over 35 (usually after 6 months of trying to become pregnant).
The woman's menstrual periods occur infrequently (fewer than nine times a year).
The woman has a previously identified abnormality of the uterus, fallopian tubes, or ovaries.
Doctors have identified or suspect problems with sperm in the man.
Age is a factor, especially for women. As women age, becoming pregnant becomes more difficult, and the risk of complications during pregnancy increases. Also, women, particularly after age 35, have a limited time to resolve infertility problems before menopause.
Tests are done depending on the suspected cause. They may include
For problems with eggs: Blood tests to measure the hormones involved in the release of eggs (ovulation) by the ovaries, such as follicle-stimulating hormone
For problems with ovulation: Ultrasonography to determine whether and when ovulation occurs
For sperm disorders: Semen analysis
Treatment of Infertility
Treatment of the cause
Sometimes assisted reproductive techniques
Measures to lessen stress, including counseling and support
The goals of treatment are
To treat the cause of infertility if possible
To make conception more likely
To reduce the time needed to conceive
Even when no cause of infertility can be identified, the couple may still be treated. In such cases, the woman may be given drugs that stimulate several eggs to mature and be released—so-called fertility drugs Treatment The ovaries do not release an egg each month, as usually occurs during a menstrual cycle.

While a couple is being treated for infertility, one or both partners may experience frustration, emotional stress, feelings of inadequacy, and guilt. They may alternate between hope and despair. Feeling isolated and unable to communicate, they may become angry at or resentful toward each other, family members, friends, or the doctor. The emotional stress can lead to fatigue, anxiety, sleep or eating disturbances, and an inability to concentrate. In addition, the financial burden and time commitment involved in diagnosis and treatment can cause marital strife.
These problems can be lessened if both partners are involved in and are given information about the treatment process (including how long it takes), regardless of which one has the diagnosed problem. Knowing what the chances of success are, as well as realizing that treatment may not be successful and cannot continue indefinitely, can help a couple cope with the stress.
Information about the following is also helpful:
When to end treatment
When to seek a second opinion
When to consider adoption
For example, if pregnancy has not occurred after 3 years of attempting it or after 2 years of being treated for infertility, the chance of pregnancy is low and adoption can be considered. Ideally, couples should ask for this information before treatment is begun.
Counseling and psychologic support, including support groups such as RESOLVE and Path2Parenthood, can help.

Information is tailored for different types of people (including lesbian and gay couples and single men and women). The web site also provides resources for adoption, including finding an adoption agency and planning for payment.
RESOLVE: The National Infertility Association: This web site provides general information about infertility, possible treatments and solutions (such as adopting or using a surrogate), and financial issues, as well as links to support groups, ways to manage stress, and advice for friends and family. It also includes resources to help LGBTQ+ (lesbian, gay, bisexual, transsexual or transgender, and queer and/or questioning) people have children.
