For a patient who is 36 years old, after how many months of regular unprotected intercourse without conception is infertility diagnosed according to most guidelines?

• A. 3 months
• B. 12 months
• C. 6 months
• D. 24 months

Answer: (C)

The main idea is that the time allowed before labeling infertility depends on age. For most people under 35, infertility is defined as not conceiving after about 12 months of regular unprotected intercourse. But for someone who is 35 or older, guidelines shorten that window to six months because fertility declines more quickly with age.

So, for a patient who is 36, six months of trying without conception meets the threshold to diagnose infertility according to most guidelines. This helps ensure that potential treatable factors are evaluated sooner rather than waiting a full year.

Three months is typically considered too short for someone this age, unless there are specific high-risk factors. Twelve months would apply to younger individuals under 35. Twenty-four months exceeds the standard threshold for infertility evaluation in this age group.
