[EXCERPT] . . . .

Thus it is on the basis of the sex hormones that the sexual differentiation of the brain occurs thus ensuring the sexually dimorphic behavior and this is found to be true with all mammals. Though the influence of the hormone has been demonstrated, the relation between the hormones and the human behavior lacks empiric study. Thus the issue of nature vs. nurture is still in the debate and research stage. The current situation is that there are effects felt of both the biological and social environs and the subject and debate over the issue has not yet been resolved conclusively. (Zhu; Cai, 2006)

Can bio-psychology may help resolve the argument?

As of now distinctions between the biological gender of human beings and the gender identity as male and female is clear cut. Except a very rare instance a person can either be a male or a female. Hormones and the creation of the biological gender- is no more in doubt. The problem is how far they are influential in making the gender identity. The gender identity is a result of the physical being and the mental concepts that result from the interaction of the individual at various stages with others, and the environmental situation influence sexual differentiation and gender identity. While hormones and chromosomes are the basis of determining the sex of a person, it is his or her own perceptions that create the identity. The identity is largely psychological and can be manipulated. (DeFries; Friedman; Corn, 1985)

While the role of hormones may have been proved, and a study on the impact of Androgens on the evolution of male gender identity shows that in human's differences in behavior from infancy through adulthood while documented, it has been researched simultaneously on animals using sex-steroid-induced differentiation and activation of the brain at critical periods. While in animals it is shown that such imprinting does alter the perceptions it is not so clear in humans and it is still debatable if gender-identity formation can be influenced by sex-steroids. In the research study of some pseudohermaphrodites with variables that included social conditioning and biologic factors in the perception of gender identity was also inconclusive because the knowledge of the hormonal factors like androgens was not accounted for. Therefore the fact that rearing played a key role cannot be discounted. (DeFries; Friedman; Corn, 1985) In future bio-psychology may be able to come up with answers to creating methods of directing the human psyche in finding its identity.
