“…A number of studies have also documented that women's self-protection behavior varies as a function of conception risk across the menstrual cycle, a key factor that exacerbates the reproductive cost of sexual assault. For example, studies have shown that women at high risk of conception, relative to women at low risk, are less likely to engage in sexually risky activities (Bröder & Hohmann, 2003; Chavanne & Gallup, 1998), infer greater threat from male strangers (Fessler, Holbrook, & Fleischman, 2014; Garver-Apgar, Gangestad, & Simpson, 2007), exert greater handgrip strength in response to sexually threatening contexts (Petralia & Gallup, 2002), and express greater bias against outgroup males (McDonald, Asher, Kerr, & Navarrete, 2011, 2015; Navarrete, Fessler, Fleischman, & Geyer, 2009). While a general motivation for self-protection should be constant across the menstrual cycle, the motivation to protect reproductive choice is most pertinent on days when conception risk is elevated, indicating that these findings are better explained by the motivation to protect reproductive choice than the SAT.…”
