What is the definition of infertility?

• A. Inability to conceive after 6 months of unprotected intercourse
• B. Inability to conceive after 12 months of unprotected intercourse
• C. Inability to carry a pregnancy to term
• D. Failure to reproduce after one year of marriage

Answer: (B)

Infertility is defined as the inability to conceive after 12 months of unprotected intercourse for most couples. This definition acknowledges that many factors can contribute to the time it takes to conceive, and a full year allows for the assessment of fertility in both partners. It reflects a standard used in the medical community to determine when a couple should seek evaluation and treatment for potential fertility issues.

While the other options mention timeframes or situations related to reproduction, they either do not conform to the established definition of infertility or are too specific without encompassing the broader circumstances of fertility. For example, the mention of six months might suggest a more urgent need for intervention, which does not align with the common clinical understanding that allows for a longer assessment period. Additionally, the inability to carry a pregnancy to term relates more specifically to issues with sustaining a pregnancy, rather than the process of conception itself, and the definition focusing on marital status fails to consider the broader context of relationships and reproductive health. Therefore, the correct answer highlights the medically accepted criterion for infertility.
