The following reections are performed with the purpose of providing considerations about the relationship of gender with sex differential evolution in Cuba in the 20th century. These considerations were based on the theory of the four bonds that constitute the Gordian knot of gender inequality. The causes inuencing the sex differential in the 20th century in Cuba were considered. We concluded that gender perspective must be present in any context where the issue of sex differential is addressed, and then enter into the reality of each social stratum and solve gender problems that may constitute elements favoring diseases onset that prevail and impact negatively on the contribution that female gender makes to life expectancy at birth.
