How Long Should We Give It?


A normal fertile couple has about a 20% chance of achieving pregnancy in any one month of unprotected intercourse. Eighty-five to ninety percent of women attempting to become pregnant can theoretically expect to conceive during the first year. The figure below compares the theoretical time to pregnancy with the actual incidence of pregnancy in fertile women over the course of one year. In general, a fertile couple can expect to achieve pregnancy sometime during two years of trying.

For patients in their twenties, infertility is most commonly defined as the failure to conceive after 12 months of unprotected intercourse.

However, after the age of 35 years, a number of physiological changes contribute to a significant decline in fertility. Accordingly, some experts believe that the time span for failure to conceive should be shortened to six months in this age group, so that treatment for infertility in older women can begin earlier.

You should consult your doctor or fertility specialist as soon as you think you may have a problem.
