How is infertility defined?

• A. Inability to conceive after 1 year of trying
• B. Inability to menstruate
• C. Inability to conceive after 6 months
• D. Inability to conceive due to blocked fallopian tubes

Answer: (D)

The main idea is that infertility is defined by the outcome over time, not by a single cause. In practice, infertility means the inability to conceive after a period of regular, unprotected intercourse. The usual benchmark is about one year for most people (six months if the person is 35 or older), after which a fertility workup is considered. This definition focuses on the chance to conceive over time, not on a particular anatomical issue. A blocked fallopian tube can certainly cause infertility by preventing the sperm and egg from meeting, but it’s one possible cause among many. It’s not how infertility is defined. Similarly, not menstruating (amenorrhea) signals a problem with ovulation or hormonal balance and can relate to fertility, but it’s not the definition of infertility itself.
