Estrogens from a wide range of sources appear to limit male reproductive abilities. There may be other consequences that reach even to the worlds of K- and r-selection.

Why so much sensitivity in males to "female" biochemistry and to "anti-androgens"?

Is this associated on a genic level with males' easy conquest by hour-glass shapes, shimmering hair, and flashing lashes? Does genomic imprinting work through estrogens to make for leaner but more territorial females and for more timid males? On a very different level, does the content of UK dumps favor liberalism and open doors for Islam?
