Conventionally defined as individuals who have undergone a sex change operation in order to become a member of the opposite sex. Yet, this definition is imposed upon transexuals from the largely hostile American mainstream; many transexuals themselves disagree with it.

First, there are many degrees of transexuality which some transexuals feel are obscured by the conventional definition. Certain individuals who identify themselves as transexual do not desire medical intervention. Others have undergone some medical procedures, such as hormone treatments, yet do not wish to undergo surgical procedures. Finally, some have undergone an entire sex-change operation.

Second, the conventional definition assumes that a transexual changes from one sex to another. This idea is based on a sex dichotomy which only concedes of two possibilities: male and female. Some scientists, such as Anne Fausto-Sterling of Brown University, have argued that there are more than two sexes.

Mainstream American culture generally considers transexuality to be indicative of abnormal or poorly adjusted individuals. Owing to their deviant status, transexuals continually face the threat of brutality from those who hate and fear them. Also, the medical establishment requires transexuals to undergo psychological testing before treatment is given. It is considered in the best interests of transexuals to be thoroughly screened before they are allowed to obtain the medical help that they desire.

Unfortunately this process is often experienced as difficult and demeaning by transexual people themselves.
