Oliven of Columbia University coined the term transgender in his reference work Sexual Hygiene and Pathology, writing that the term which had previously been used, transsexualism , "is misleading; actually, 'transgenderism' is meant, because sexuality is not a major factor in primary transvestism. A Movement Whose Time has Come", circulated in , identified transgender as a term to unify all forms of gender nonconformity; in this way transgender has become synonymous with queer. These terms have now been superseded by " trans man " and " trans woman ", respectively, and the terms "trans-masculine" or "trans-feminine" are increasingly in use. However, the concerns of the two groups are sometimes different; for example, transsexual men and women who can pay for medical treatments or who have institutional coverage for their treatment are likely to be concerned with medical privacy and establishing a durable legal status as their gender later in life. Distinctions between the terms transgender and transsexual are commonly based on distinctions between gender psychological, social and sex physical.
