Female premarital sex is more likely to be restricted in societies with higher direct paternal investment.


This is a proxy for whether men control the prevalence of premarital sex. PP = 23.58%, b=-.22, CI=(-.72, .27). This suggests that higher direct paternal investment may actually result in fewer restrictions on premarital sex, though the result is not significant.
