Infertility is a discretionary health condition; although it carries with it important life course implications, treatment is rarely necessary for health reasons. Sociological theories of medical help-seeking emphasize demographic factors, perceived need, and enabling conditions in health services utilization, but we find that social cues are also strongly associated with health services utilization for infertility. Adjusted for conventional predictors of medical help-seeking, several social cue indicators have significant associations with utilization, including having friends and family with children, perceiving infertility stigma, and having a partner and/or family member who encourages treatment. Perceived need accounts for the largest portion of the variation in utilization. Enabling conditions explain less of the variance than social cues. Social cues should be especially important for discretionary health services utilization. Studies of service utilization for discretionary health conditions should explicitly incorporate a range of measures of social cues into their models.Sociologists, psychologists, and others have long been interested in uncovering the factors associated with the utilization of health services. Much sociological research on health services utilization has been inspired by and built upon Andersen's (1968) Socio-Behavioral Model of Health Services Utilization, which proposed that utilization results from predisposing characteristics, enabling resources, and need. Studies using Andersen's model have found that need-based factors often account for more explained variance in health services utilization than any single other group of factors (Andersen and Newman 1973;Gilbert, Branch, and Longmate 1993;Menec and Chipperfield 2001;Wolinsky and Johnson 1991). Need for services cannot be objectively defined, however, because perceived need for services is socially constructed (Pescosolido and Boyer 2010). Symptoms need to be interpreted as a medical problem, and a medical solution needs to be selected as the best alternative before individuals consider seeking medical help. Social indications from significant others about the value of health services utilization are central to this process of interpreting
