Which statement best defines infertility in a reproductive health context?

• A. Inability to carry a pregnancy to term
• B. Failure to conceive after 1 year of regular unprotected sex
• C. Infertility defined after 6 months in all women
• D. Inability to ovulate in any cycle

Answer: (B)

Infertility is defined by the length of time trying to conceive without success during regular unprotected intercourse. The standard clinical threshold is not conceiving after about one year, which is why the statement describing failure to conceive after 1 year is the best match. This time frame helps clinicians decide when to begin evaluation for underlying factors in the couple. Context that helps you remember: most healthy couples conceive within a year, so if conception hasn’t occurred by then, it’s reasonable to investigate potential female, male, or combined factors. In people who are older (for example, 35 or older) or have known risk factors, doctors may start evaluation sooner, often after six months. Why the other statements aren’t the definition: Inability to carry a pregnancy to term refers to pregnancy loss or the ability to sustain a pregnancy, not the initial ability to conceive. Inability to ovulate in any cycle describes a specific cause—anovulation—rather than the overall definition of infertility. Infertility defined after six months in all women is incorrect because the recommended evaluation window is not the same for everyone; age and risk factors change when evaluation begins.
