We revisit the claims about the biological underpinnings of economic behavior by specifically exploring if observed gender differences in risk-time preferences can be explained by natural fluctuations in progesterone-estradiol levels during the menstrual cycle and by prenatal exposure to testosterone and estrogen levels. We find no effect of the menstrual cycle and thereby, of associated fluctuations in progesterone and estradiol levels or of the digit ratio on either risk or time preferences.
