Which term is clinically defined as the capacity to have a live birth?

• A. Fecundity
• B. Fertility
• C. Fecundability
• D. Reproductive efficiency

Answer: (A)

The main idea is distinguishing biological capacity from timing or outcomes. Fecundity specifically refers to the biological potential to reproduce and have a live birth. It captures the inherent capability to conceive and carry to term, regardless of whether conception occurs in a given cycle or a live birth actually happens. Fecundability, by contrast, is about the probability of achieving pregnancy in a single menstrual cycle, which is a per-cycle measure, not overall capacity. Fertility is a broader term often used to describe the ability to conceive and bear children in general, but when we talk about the capacity to have a live birth as a potential rather than the realized outcome, fecundity is the most precise fit. Reproductive efficiency isn’t a standard clinical term in this context. So, the term that best matches “capacity to have a live birth” is fecundity.
