Fecundability

Meaning

Fecundability is a fundamental epidemiological and reproductive health measure defined as the probability of achieving a clinical pregnancy within a single menstrual cycle, assuming regular, unprotected sexual intercourse. This metric quantifies the intrinsic reproductive capacity of a couple during a specific cycle. It is an essential concept used in fertility research and clinical counseling to estimate the time required for conception and to define the threshold for infertility diagnosis. Fecundability naturally varies based on maternal age, frequency of intercourse, and underlying reproductive health factors.
