Estrogens are hormones that are play important roles in the reproductive system.
<h3>What are the roles played by estrogen?</h3>
The environmental estrogen introduced to the male cells has the ability to recognise the binding sites of the receptors on the male cells.

When the binding occurs, there would be a conformational change within the cell leading to:
- modulation of protein synthesis and
- development of the female secondary reproductive characteristics.
