Which statement correctly compares infertility timeframes for females and males?

• A. Female infertility is defined after 6 months and male infertility after 12 months
• B. Female infertility is defined after 12 months and male infertility after 6 months
• C. Female infertility is defined after 12 months and male infertility after 12 months
• D. Female infertility is defined after 6 months and male infertility after 6 months

Answer: (B)

Infertility evaluation timing differs by gender because the ways we assess fertility in men and women differ in practicality and typical urgency. A semen analysis in men provides a relatively quick and straightforward snapshot of fertility status, so clinicians often consider male factor issues earlier, around six months of trying. Female fertility, however, is more closely tied to ovulatory function and age-related decline, which often requires a longer window of trying to conceive before labeling infertility and pursuing extensive testing. Therefore, the standard pairing used here sets a longer 12-month threshold for female infertility and a shorter 6-month threshold for male infertility. In real practice, guidelines can adjust these timelines based on age and risk factors, but this framing aligns with the test’s intended distinction.
