“…Despite their potential impact, there has been limited research on individuals' perceptions of their own fecundity in the general population, including sources of information or indicators that inform these perceptions. However, as delayed childbearing (Gossett, Nayak, Bhatt, & Bailey, 2013;Mills, Rindfuss, McDonald, te Velde, & ESHRE Reproduction and Society Task Force, 2011), advancement of assisted reproductive technologies (Sunderam et al, 2018;Waldby, 2015), and public conversations around infertility become more commonplace (Feasey, 2019;Sangster & Lawson, 2015;Willson, Perelman, & Goldman, 2019), individuals are more exposed to messages about possible limitations to their "biological clocks" than they were decades ago. Moreover, most prior research on selfperceptions or related topics (e.g., fertility awareness) has focused on nonrepresentative samples (e.g., college students; Meissner, Schippert, & von Versen-H€ oynck, 2016;Whitten, Remes, Sabarre, Khan, & Phillips, 2013) or select populations (e.g., unmarried individuals; Polis & Zabin, 2012), but given known disparities in infertility and treatment seeking by race/ ethnicity, education, and other factors (Bitler & Schmidt, 2012;Craig, Peck, & Janitz, 2019;Greil, McQuillan, Shreffler, Johnson, & Slauson-Blevins, 2011a;Kelley, Qin, Marsh, & Dupree, 2019), it is imperative to examine self-perceptions of fecundity in the general population.…”
