The polarity of the sexes is rooted in the genic sex. The qualities which constitute masculinity and femininity are psychobiological secondary (sex) characteristics. They are epigenetic phenomena evolved from the interaction of man's biological givens with the civilization. The polarity of the sexes changes in our civilization faster than before. The potential for psychological change is in the process of identification primarily of the infants of both sexes with the mother. Socioeconomic and cultural changes bear influence on the structure of the family and promote the equalization of the sexes.
性别的两极分化植根于基因性别。构成男性气质和女性气质的特质是心理生物学上的第二性征。它们是人类生物学禀赋与文明相互作用而演化出的表观遗传现象。在我们的文明中，性别的两极分化比以往变化得更快。心理变化的潜力主要在于两性婴儿对母亲的认同过程。社会经济和文化变革对家庭结构产生影响，并促进性别平等。
