    Standards of Care: The Hormonal and Surgical Sex Reassignment 
                    of Gender Dysphoric Persons

1. Introduction

As of the beginning of 1979, an undocumentable estimate of the
number of adult Americans hormonally and surgically sex-reassigned
ranged from 3,000 to 6,000. Also undocumentable is the estimate
that between 30,000 and 60,000 U.S.A. citizens consider themselves
to be valid candidates for sex reassignment. World estimates are
not available. As of mid-1978, approximately 40 centers in the
Western hemisphere offered surgical sex reassignment to persons
having a multiplicity of behavioral diagnoses applied under a
multiplicity of criteria.

In recent decades, the demand for sex-reassignment has increased as
have the number and variety of possible psychologic, hormonal and
surgical treatments. The rationale upon which such treatments are
offered have become more and more complex. Varied philosophies of
appropriate care have been suggested by various professionals
identified as experts on the topic of gender identity. However,
until the present, no statement of the standard of care to be
offered to dysphoric patients (sex reassignment applicants) has
received official sanction by any identifiable professional group.
The present document is designed to fill that void.

2. Statement of Purpose

Harry Benjamin International Gender Dysphoria Association, Inc.,
presents the following as its explicit statement of the appropriate
standards of care to be offered to applicants for hormonal and
surgical sex reassignment.

3. Definitions

3.1  _Standard of care_. The standards of care, as listed below,
     are  _minimal_ requirements and are not to be construed as 
     standards of care. It is recommended that professionals
     involved in the management of sex reassignment cases use the
     following as _minimal_ criteria for the evaluation of their
     work. It should be  noted that some experts on gender identity
     recommend that the time parameters listed below be doubled, or
     tripled. It is recommended that the reasons for any exceptions
     to these standards, in the management of any individual case,
     be  carefully documented. Professional opinions differ
     regarding the permissibility of, and the circumstances
     warranting, any such exception.

3.2  _Hormonal sex reassignment_. Hormonal sex reassignment refers
     to the administration of androgens to genotypic and phenotypic
     females, and the administration of estrogens and/or
     progesterones to genotypic and phenotypic males, for the
     purpose of effecting somatic changes in order for the patient
     to more closely approximate the physical appearance of the
     genotypically-other sex. Hormonal sex reassignment does not
     refer to the administration of hormones for the purpose of
     medical care and/or research conducted for the treatment of
     non-gender dysphoric medical conditions (e.g., aplastic
     anemia, impotence, cancer, etc.).

3.3  _Surgical sex reassignment_. Genital surgical sex reassignment 
     refers to surgery of the genitalia and/or breasts performed
     for the purpose of altering the morphology in order to
     approximate the physical appearance of the genetically-other
     sex in persons diagnosed as gender dysphoric. Such surgical
     procedures as mastectomy, reduction mammoplasty, augmentation
     mammoplasty, castration, orchiectomy, penectomy, vaginoplasty,
     hysterectomy, salpingectomy, vaginectomy, oophorectomy, and
     phalloplasty -- in the absence of any diagnosable birth defect
     or other medically defined pathology, except gender dysphoria,
     are included in this category labeled surgical sex
     reassignment.

     Non-genital surgical sex reassignment refers to any and all
     other surgical procedures of non-genital, or non-breast, sites
     (nose, throat, chin, cheeks, hips, etc.) conducted for the
     purpose of effecting a more masculine appearance in a genetic
     female or for the purpose of effecting a more feminine
     appearance in a genetic male, in the absence of identifiable
     pathology which would warrant such surgery regardless of the
     patient's genetic sex (facial injuries, hermaphroditism,
     etc.).

3.4  _Gender dysphoria_. Gender dysphoria herein refers to that   
     psychological state whereby a person demonstrates
     dissatisfaction with their sex of birth and the sex role, as
     socially defined, which applies to that sex, and who requests
     hormonal and surgical sex reassignment. Gender dysphoria,
     herein, does not refer to cases of infant sex reassignment or
     reannouncement. Gender dysphoria, therefore, is the primary
     working diagnosis applied to any and all persons requesting
     surgical and hormonal sex reassignment.

3.5 _Clinical behavioral scientist_.

     [1] Possession of an academic degree in a behavioral science
     does not necessarily attest to the possession of sufficient
     training or competence to conduct psychotherapy, psychologic
     counseling, nor diagnosis of gender identity problems. Persons
     recommending sex reassignment surgery or hormone therapy
     should have documented training and experience in the
     diagnosis and treatment of a broad range of psychologic     
     conditions. Licensure or certification as a psychological    
     therapist or counselor does not necessarily attest to
     competence in sex therapy. Persons recommending sex
     reassignment surgery or hormone therapy should have the
     documented training and to diagnose and treat a broad range of
     sexual conditions. Certification in sex therapy or counseling
     does not necessarily attest to competence in the diagnosis and
     treatment of gender identity conditions or disorders. Persons
     recommending sex reassignment surgery or hormone therapy
     should have proven competence in general psychotherapy, sex
     therapy, and gender counseling/therapy.

     _Any and all_ recommendations for sex reassignment surgery and
     hormone therapy should be made only by clinical behavioral
     scientists possessing the following minimal documentable
     credentials and expertise:

3.5.1     A minimum of a Masters Degree in a clinical behavioral
          science, granted by an institution of education
          accredited by a national or regional accrediting board.

3.5.2     One recommendation, of the two required for sex
          reassignment surgery, must be made by a person possessing
          a doctoral degree (e.g. Ph.D., Ed.D., D.Sc., D.S.W.,
          Psy.D., or M.D.) in a clinical behavioral science,
          granted by an institution of education accredited by a
          national or regional accrediting board.

3.5.3     Demonstrated competence in psychotherapy as indicated by
          a license to practice medicine, psychotherapy, clinical
          social work, marriage and family counseling, or social
          psychotherapy, etc., granted by the state of residence.
          In states where no such appropriate license board exists,
          persons recommending sex reassignment surgery or hormone
          therapy should have been certified by a nationally-known
          and reputable association, based on education and
          experience criteria and, preferably, some form of testing
          (and not simply on membership received for dues paid) as
          an accredited or certified therapist/counselor (e.g.
          American Board of Psychiatry and Neurology, Diplomate in 
          Psychology from the American Board of Professional
          Psychologists, Certified Clinical Social Workers,
          American Association of Marriage and Family Therapists,
          American Professional Guidance Association, etc.).

3.5.4     Demonstrated specialized competence in sex therapy and
          theory as indicated by documentable training and
          supervised clinical experience in sex therapy (in some
          states professional licensure requires training in human
          sexuality; also, persons should have approximately the
          training and experience required for certification as a
          Sex Therapist or Sex Counselor by the American
          Association of Sex Educators, Counselors and       
          Therapists, or as required for membership in the Society
          for Sex Therapy and Research). Continuing education in
          human sexuality and sex therapy should also be
          demonstrable.

3.5.5     Demonstrated and specialized competence in therapy,
          counseling, and diagnosis of gender identity disorders as
          documentable by training and supervised clinical
          experience, along with continuing education.

     The behavioral scientists recommending sex reassignment
     surgery and hormone therapy and the physician and surgeon(s)
     who accept those recommendations share the responsibility for
     certifying that the recommendations are made based on
     competency indicators as described above.

4. Principles and Standards

_Introduction_

4.1.1     Principle 1. Hormonal and surgical sex reassignment is
          extensive in its effects, is invasive to the integrity of
          the human body, has effects and consequences which are
          not, or are not readily, reversible, and may be requested
          by persons experiencing short-termed delusions or beliefs
          which may later be changed and reversed.

4.1.2     Principle 2. Hormonal and surgical sex reassignment are 
          procedures requiring justification and are not of such
          minor consequence as to be performed on an elective
          basis.

4.1.3     Principle 3. Published and unpublished case histories are
          known in which the decision to undergo hormonal and
          surgical sex reassignment was, after the fact, regretted
          and the final result of such procedures proved to be
          psychologically dehabilitating to the patients.

4.1.4     Standard 1. Hormonal and/or surgical[2] sex reassignment
          on demand (i.e., justified simply because the patient has
          requested such procedures) is contraindicated. It is
          herein declared to be professionally improper to conduct,
          offer, administer or perform hormonal sex reassignment
          and/or surgical sex reassignment without careful
          evaluation of the patient's reasons for requesting such
          services and evaluation of the beliefs and attitudes upon
          which such reasons are based.

4.2.1     Principle 4. The analysis or evaluation of reasons,
          motives, attitudes, purposes, etc., requires skills not
          usually associated with the professional training of
          persons other than clinical behavioral scientists.

4.2.2     Principle 5. Hormonal and/or surgical sex reassignment is 
          performed for the purpose of improving the quality of
          life as subsequently experienced and such experiences are
          most properly studied and evaluated by the clinical
          behavioral scientist.

4.2.3     Principle 6. Hormonal and surgical sex reassignment are
          usually offered to persons, in part, because a
          psychiatric/psychologic diagnosis of transsexualism (see
          _DSM-III_, Section 302.5X), or some related diagnosis,
          has been made. Such diagnoses are properly made only by
          clinical behavioral scientists.

4.2.4     Principle 7. Clinical behavioral scientists, in deciding
          to make the recommendation in favor of hormonal and/or
          surgical sex reassignment share the moral responsibility
          for that decision with the physician and/or surgeon who
          accepts that recommendation.

4.2.5     Standard 2. Hormonal and surgical (genital and breast)
          sex reassignment must be made by a firm written
          recommendation for such procedures made by a clinical
          behavioral scientist who can justify making such a
          recommendation by appeal to training or professional
          experience in dealing with sexual disorders, especially
          the disorders of gender identity and role.

4.3.1     Principle 8. The clinical behavioral scientist's
          recommendation for hormonal and/or surgical sex
          reassignment should, in part, be based upon an evaluation
          of how well the patient fits the diagnostic criteria for
          transsexualism as listed in the DSM-III-R category 302.50
          to wit:[3]

          A.   Persistent discomfort and sense of                 
               inappropriateness about one's assigned sex.

          B.   Persistent preoccupation for at least two years    
               with getting rid of one's primary and secondary    
               sex characteristics and acquiring the sex          
               characteristics of the other sex.

          C.   The person has reached puberty.

     This definition of transsexualism is herein interpreted not to
     exclude persons who meet the above criteria but who otherwise
     may, on the basis of their past behavioral histories, be
     conceptualized and classified as transvestites and/or
     effeminate male homosexuals or masculine female homosexuals.

4.3.2     Principle 9. The intersexed patient (with a documented
          hormonal or genetic abnormality) should first be treated
          by procedures commonly accepted as appropriate for such
          medical conditions.

4.3.3     Principle 10. The patient having a psychiatric diagnosis
          (i.e., schizophrenia) in addition to a diagnosis of
          transsexualism should first be treated by procedures
          commonly accepted as appropriate for such non-transsexual
          psychiatric diagnoses.


4.3.4     Standard 3. Hormonal and surgical sex reassignment may be
          made available to intersexed patients and to patients
          having non-transsexual psychiatric/psychological
          diagnoses if the patient and therapist have fulfilled the
          requirements of the herein listed standards; if the
          patient can be reasonably expected to be habilitated or
          rehabilitated, in part, by such hormonal and surgical sex
          reassignment procedures; and if all other commonly
          accepted therapeutic approaches to such intersexed or
          non-transsexual psychiatrically/psychologically diagnosed
          patients have been either attempted, or considered for
          use prior to the decision not to use such alternative
          therapies. The diagnosis of schizophrenia, therefore,
          does not necessarily preclude surgical and hormonal sex
          reassignment.

_Hormonal Sex Reassignment_

4.4.1     Principle 11. Hormonal sex reassignment is both
          therapeutic and diagnostic in that the patient requesting
          such therapy either reports satisfaction or
          dissatisfaction regarding the results of such therapy.

4.4.2     Principle 12. Hormonal sex reassignment may have some
          irreversible effects (infertility, hair growth, voice
          deepening, and clitoral enlargement in the female-to-male
          patient and infertility and breast growth in the male-to-
          female patient) and, therefore, such therapy must be
          offered only under the guidelines proposed in the present
          standards.

4.4.3     Principle 13. Hormonal sex reassignment should precede
          surgical sex reassignment as its effects (patient
          satisfaction or dissatisfaction) may indicate or
          contraindicate later surgical sex reassignment.

4.4.4     Standard 4.[4] The initiation of hormonal sex
          reassignment shall be preceded by recommendation for such
          hormonal therapy made by a clinical behavioral scientist.

4.5.1     Principle 14. The administration of androgens to females
          and of estrogens and/or progesterones to males may lead
          to mild or serious health-threatening complications.

4.5.2     Principle 15. Persons who are in poor physical health, or
          who have identifiable abnormalities in blood chemistry,
          may be at above average risk to develop complications
          should they receive hormonal medication.

4.5.3     Standard 5. The physician prescribing hormonal medication
          to a person for the purpose of effecting hormonal sex
          reassignment must warn the patient of possible negative
          complications which may arise and that physician should
          also make available to the patient (or refer the patient
          to a facility offering) monitoring of relevant          
          blood chemistries and routine physical examinations
          including, but not limited to, the measurement of SGPT in
          persons receiving testosterone and the measurement of
          SGPT, bilirubin, triglycerides and fasting glucose in
          persons receiving estrogens.

4.6.1     Principle 16. The diagnostic evidence for transsexualism
          (see 4.3.1 above) requires that the clinical behavioral
          scientist have knowledge, independent of the patient's
          verbal claim, that the dysphoria, discomfort, sense of
          inappropriateness and wish to be rid of one's own
          genitals, have existed for at least two years. This
          evidence may be obtained by interview of the          
          patient's appointed informant (friend or relative) or it
          may best be obtained by the fact that the clinical
          behavioral scientist has professionally known the patient
          for an extended period of time.

_Surgical (Genital and/or Breast) Sex Reassignment_

4.7.1     Principle 17. Peer review is a commonly accepted
          procedure in most branches of science and is used
          primarily to ensure maximal efficiency and correctness of
          scientific decisions and procedures.

4.7.2     Principle 18. Clinical behavioral scientists must often
          rely on possibly unreliable or invalid sources of
          information (patient's verbal reports or the verbal
          reports of the patient's families and friends) in making
          clinical decisions and in judging whether or not a
          patient has fulfilled the requirements of the herein
          listed standards.

4.7.3     Principle 19. Clinical behavioral scientists given the
          burden of deciding who to recommend for hormonal and
          surgical sex reassignment and for whom to refuse such
          recommendations are subject to extreme social pressure
          and possible manipulation as to create an atmosphere in
          which charges of laxity, favoritism, sexism, financial
          gain, etc., may be made.

4.7.4     Principle 20. A plethora of theories exist regarding the
          etiology of gender dysphoria and the purposes or goals of
          hormonal and/or surgical sex reassignment such that the
          clinical behavioral scientist making the decision to
          recommend such reassignment for a patient does not enjoy
          the comfort or security of knowing that his or her
          decision would be supported by the majority of his or her
          peers.

4.7.8     Standard 7. The clinical behavioral scientist
          recommending that a patient receive surgical (genital and
          breast) sex reassignment must obtain peer review, in the
          format of a clinical behavioral scientist peer who will
          personally examine the patient applicant, on at least one
          occasion, and who will, in writing, state that he or she
          concurs with the decision of the original clinical
          behavioral scientist. Peer review (a second opinion) is
          not required for hormonal sex reassignment.  Non-
          genital/breast surgical sex reassignment does not require
          the recommendation of a behavioral scientist. At least
          one of the two behavioral scientists making the favorable
          recommendation for surgical (genital and breast) sex
          reassignment must be a doctoral level clinical behavioral
          scientist.[5]

4.8.1     Standard 8. The clinical behavioral scientist making the
          primary recommendation in favor of genital (surgical) sex
          reassignment shall have known the patient in a
          psychotherapeutic relationship for at least 6 months
          prior to making said recommendation. That clinical
          behavioral scientist should have access to the results of
          psychometric testing (including IQ testing of the
          patient) when such testing is clinically indicated.

4.9.1     Standard 9. Genital sex reassignment shall be preceded by
          a period of at least 12 months during which time the
          patient lives full-time in the social role of the
          genetically-other sex.

4.10.1    Principle 21. Genital surgical sex reassignment includes
          the invasion of, and the alteration of, the genitourinary
          tract. Undiagnosed pre-existing genitourinary disorders
          may complicate later genital surgical sex reassignment.

4.10.2    Standard 10.[6] Prior to genital surgical sex
          reassignment a urological examination should be conducted
          for the purpose of identifying and perhaps treating
          abnormalities of the genitourinary tract.

4.11.1    Standard 11. The physician administering or performing
          surgical (genital) sex reassignment is guilty of
          professional misconduct if he or she does not receive
          written recommendations in favor of such procedures from
          at least two clinical behavioral scientists; at least one
          of which is a doctoral level clinical behavioral
          scientist and one of whom has known the patient in a
          professional relationship for at least 6 months.

_Miscellaneous_

4.12.1    Principle 22. The care and treatment of sex reassignment
          applicants or patients often causes special problems for
          the professionals offering such care and treatment. These
          special problems include, but are not limited to: the
          need for the professional to cooperate with the education
          of the public to justify his or her work, the need to
          document the case history perhaps more completely than is
          customary in general patient care, the need to respond to
          multiple, nonpaying, service applicants and the need to
          be receptive and responsive to the extra demands for
          services and assistance often made by sex reassignment
          applicants as compared to other patient groups.

4.12.2    Principle 23. Sex reassignment applicants often have need
          for post-therapy (psychologic, hormonal and surgical)
          follow-up care for which they are unable or unwilling to
          pay.

4.12.3    Principle 24. Sex reassignment applicants are often in a
          financial status which does not permit them to pay
          excessive professional fees.

4.12.4    Standard 12. It is unethical for professionals to charge
          sex reassignment applicants "whatever the traffic will
          bear" or excessive fees far beyond the normal fees
          changed for similar services by the professional. It is
          permissible to charge sex reassignment applicants for
          services in advance of the tendering of such services
          even if such an advance fee arrangement is not typical of
          the professional's practice. It is permissible to charge
          patients, in advance, for expected services such as post-
          therapy follow-up care and/or counseling. It is unethical
          to charge patients for services which are essentially
          research and which services do not directly benefit the
          patient.

4.13.1    Principle 25. Sex reassignment applicants often
          experience social, legal and financial discrimination not
          known, at present, to be prohibited by federal or state
          law.

4.13.2    Principle 26. Sex reassignment applicants often must
          conduct formal or semiformal legal proceedings (i.e., in-
          court appearances against insurance companies or in
          pursuit of having legal documents changed to reflect
          their new sexual and genderal status, etc.).

4.13.3    Principle 27. Sex reassignment applicants, in pursuit of
          what are assumed to be their civil rights as citizens,
          are often in need of assistance (in the form of copies of
          records, letters of endorsement, court testimony, etc.)
          from the professionals involved in their case.

4.13.4    Standard 13. It is permissible for a professional to
          charge only the normal fee for services needed by a
          patient in pursuit of his or her civil rights. Fees
          should not be charged for services for which, for other
          patient groups, such fees are not normally charged.

4.14.1    Principle 28. Hormonal and surgical sex reassignment has
          been demonstrated to be a rehabilitative, or
          habilitative, experience for properly selected adult
          patients.

4.14.2    Principle 29. Hormonal and surgical sex reassignment are
          procedures which must be requested by, and performed only
          with the agreement of, the patient having informed
          consent. Sex reannouncement or sex reassignment
          procedures conducted on infantile or early childhood
          intersexed patients are common medical practices and are
          not included in or affected by the present discussions.

4.14.3    Principle 30. Sex reassignment applicants often, in their
          pursuit of sex reassignment, believe that hormonal and
          surgical sex reassignment have fewer risks than such
          procedures are known to have.

4.14.4    Standard 14. Hormonal and surgical sex reassignment may
          be conducted or administered only to persons obtaining
          their legal majority (as defined by state law) or to
          persons declared by the courts as legal adults
          (emancipated minors).

4.15.1    Standard 15. Hormonal and surgical sex reassignment may
          be conducted or administered only after the patient has
          received full and complete explanations, preferably in
          writing, in words understood by the patient applicant, of
          all risks inherent in the requested procedures.

4.16.1    Principle 31. Gender dysphoric sex reassignment
          applicants and patients enjoy the same rights to medical
          privacy as does any other patient group.

4.16.2    Standard 16. The privacy of the medical records of the
          sex reassignment patient shall be safeguarded according
          to the procedures in use to safeguard the privacy of any
          other patient group.

5. Explication

5.1       Prior to the initiation of hormonal sex reassignment:

5.1.1     The patient must demonstrate that the sense of discomfort
          with the self and the urge to rid the self of the
          genitalia and the wish to live in the genetically-other
          sex role have existed for at least 2 years.

5.1.2     The patient must be known to a clinical behavioral
          scientist for at least 3 months and that clinical
          behavioral scientist must endorse the patient's request
          for hormone therapy.

5.1.3     Prospective patients should receive a complete physical
          examination which includes, but is not limited to, the
          measurement of SGPT in persons to receive testosterone
          and the measurement of SGPT, bilirubin, triglycerides and
          fasting glucose in persons to receive estrogens.

5.2       Prior to the initiation of genital or breast sex
          reassignment (penectomy, orchiectomy, castration,
          vaginoplasty, mastectomy, hysterectomy, oophorectomy,
          salpingectomy, vaginectomy, phalloplasty, reduction
          mammoplasty, breast amputation):

5.2.1     See 5.1.1, above.

5.2.2     The patient must be known to a clinical behavioral
          scientist for at least 3 months and that clinical
          behavioral scientist must endorse the patient's request
          for genital surgical sex reassignment.

5.2.3     The patient must be evaluated at least once by a clinical
          behavioral scientist other than the clinical behavioral
          scientist specified in 5.2.2 above and that second
          clinical behavioral scientist must endorse the patient's
          request for genital sex reassignment. At least one of the
          clinical behavioral scientists making the recommendation
          for genital sex reassignment must be a doctoral        
          level clinical behavioral scientist.

5.2.4     The patient must have been living in the genetically-
          other sex role for at least one year.

5.3       During and after services are provided:

5.3.1     The patient's right to privacy should be honored.

5.3.2     The patient must be charged only appropriate fees and
          these fees may be levied in advance of services.

Notes:

[1]  The drafts of these Standards of Care dated 2/79 and 1/80
     required that all recommendations for hormonal and/or surgical
     sex reassignment be made by licensed psychologists or
     psychiatrists. That requirement was rescinded, and replaced by
     the definition in section 3.5, in 3/81.

[2]  The present standards provide no guidelines for the granting
     of non-genital/breast cosmetic or reconstructive surgery. The 
     decision to perform such surgery is left to the patient and  
     surgeon. The original draft of this document did recommend the
     following however (rescinded 1/80):

          "Non-genital sex reassignment (facial, hip, limb, etc.)
          shall be preceded by a period of at least 6 months during
          which time the patient lives full-time in the social role
          of the genetically other sex."

     Disorders_ (Third Edition-Revised).  Washington, D.C. The
     American Psychiatric Association, 1987.

[4]  This standard, in the original draft, recommended that the
     patient must have lived successfully in the social/gender role
     of the genetically-other sex for at least 3 months prior to
     the initiation of hormonal sex reassignment. This requirement
     was rescinded 1/80.

[5]  In the original and 1/80 version of these standards, one of
     the clinical behavioral scientists was required to be a
     psychiatrist. That requirement was rescinded in 3/81.

[6]  This requirement was rescinded 1/90.
