There is a growing interest in the effects of changes in conception risk across the menstrual cycle on interpersonal attitudes. The purpose of this study was to examine whether altruistic behavior is different depending on conception risks. An online survey was conducted on a total of 94 Japanese female university students. Conception risk was assessed based on self-reported information regarding days since the last menstrual period. Altruistic behavior was measured from participants' answers to a questionnaire regarding altruistic behavior towards three personal relationships, i.e., family members, friends and acquaintances, and strangers. Variables related to perceived vulnerability to disease (PVD) and fear of rape were also measured from the questionnaire. ANOVA indicated that the interaction effect of conception risk × PVD was statistically significant. Among women with high risk of conception, altruistic behavior score toward strangers was greater when their PVD score was high. ANOVA also indicated that conception risk × fear of rape was statistically significant. Among women with high risk of conception, altruistic behavior score for all personal relationships was lower when their fear of rape score was low. The results remained significant even after controlling for menstrual regularity and low-dose oral contraceptive use. The findings of the study may provide new insights into interpersonal attitudes, especially intergroup biases in women.
