Chromosomes initially determine a personâ€™s sex but most gender development actually comes about through the influence of hormones. In the womb, hormones act upon brain development and cause the development of reproductive organs. At puberty, a burst of hormonal activity triggers the development of secondary sexual characteristics.
What is it? Androgyny is displaying a balance of similarly high levels of masculine and feminine characteristics in oneâ€™s personality.
Why is it important to make the distinction? In everyday life, the terms sex and gender are often used interchangeably suggesting they are one and the same. Sex and gender are however, distinct and separate concepts.
