Transgender hormone therapy, also called hormone replacement therapy (HRT) or gender-affirming hormone therapy (GAHT), is a form of
- transmasculine people; consists of androgens and antiestrogens.
- antiandrogens.
Eligibility for transgender hormone therapy may be concluded by assessing a patient for gender dysphoria or persistent gender incongruence, though many medical institutions now used an informed consent model. This model ensures patients are informed of the procedure process, including possible benefits and risks, while removing many of the historical barriers needed to start hormone therapy. Treatment guidelines for therapy have been developed by several medical associations.
Some
Requirements
The formal requirements to begin gender-affirming hormone therapy vary widely depending on geographic location and specific institution. Gender affirming hormones can be prescribed by a wide range of medical providers including, but not limited to, primary care physicians, endocrinologists, and obstetrician-gynecologists.[2]
Historically, many health centers required a psychiatric evaluation and/or a letter from a therapist before beginning therapy. Many centers now use an
) advocate for this type of informed consent model.The World Professional Association for Transgender Health (WPATH) Standards of Care, 7th edition, note that both of these approaches to care are appropriate.[2]
Gender dysphoria
Many international guidelines and institutions require persistent, well-documented gender dysphoria as a pre-requisite to starting gender-affirmation therapy.

Guidelines
For transgender youth, the Dutch protocol existed as among the earlier guidelines for hormone therapy by delaying puberty until age 16.[9][10] The World Professional Association for Transgender Health (WPATH) and the Endocrine Society later formulated guidelines that created a foundation for health care providers to care for transgender patients.[11][12] UCSF guidelines are also sometimes used.[3] There is no generally agreed-upon set of guidelines, however.[13]
Delaying puberty in adolescents
Adolescents experiencing gender dysphoria may opt to undergo puberty-suppressing hormone therapy at the onset of puberty. The Standards of Care set forth by
The preferred puberty-suppressing agent for both individuals assigned male at birth and individuals assigned female at birth is a
Feminizing hormone therapy
The desired effects of feminizing hormone therapy focus on the development of feminine secondary sex characteristics. These desired effects include: breast tissue development, redistribution of body fat, decreased body hair, reduction of muscle mass, and more.[18] The table below summarizes some of the effects of feminizing hormone therapy in transgender women:

Masculinizing hormone therapy
Unlike feminizing hormone therapy, individuals undergoing masculinizing hormone therapy do not usually require additional hormone suppression such as estrogen suppression. Therapeutic doses of testosterone are usually sufficient to inhibit the production of estrogen to desired physiologic levels.[15]
The desired effects of masculinizing hormone therapy focus on the development of masculine secondary sex characteristics. These desired effects include: increased muscle mass, development of facial hair, voice deepening, increase and thickening of body hair, and more.[34]
Reversible Changes | Irreversible Changes |
---|---|
Increased libido | Deepening of voice |
Redistribution of body fat | Growth of facial/body hair |
Cessation of ovulation/menstruation | Male-pattern baldness |
Increased muscle mass | Enlargement of clitoris |
Increased perspiration | Growth spurt/closure of growth plates |
Acne | Breast atrophy |
Increased RBC count |
Safety
Hormone therapy for transgender individuals has been shown in medical literature to be generally safe, when supervised by a qualified medical professional.[35] There are potential risks with hormone treatment that will be monitored through screenings and lab tests such as blood count (hemoglobin), kidney and liver function, blood sugar, potassium, and cholesterol.[33][17] Taking more medication than directed may lead to health problems such as increased risk of cancer, heart attack from thickening of the blood, blood clots, and elevated cholesterol.[33][36]

Fertility consideration
Transgender hormone therapy may limit fertility potential.
A study presented at ENDO 2019 (the Endocrine Society's conference) shows that even after one year of treatment with testosterone, a transgender man can preserve his fertility potential.[40]
Treatment eligibility
Many providers use informed consent, whereby someone seeking hormone therapy can sign a statement of informed consent and begin treatment without much gatekeeping. For other providers, eligibility is determined using major diagnostic tools such as ICD-11 or the Diagnostic and Statistical Manual of Mental Disorders (DSM) to classify a patient with gender dysphoria. Psychiatric conditions can commonly accompany or present similar to gender incongruence and gender dysphoria. For this reason, patients are assessed using DSM-5 criteria or ICD-11 criteria in addition to screening for psychiatric disorders. The Endocrine Society requires physicians that diagnose gender dysphoria and gender incongruence to be trained in psychiatric disorders with competency in ICD-11 and DSM-5. The healthcare provider should also obtain a thorough assessment of the patient's mental health and identify potential psychosocial factors that can affect therapy.[41]
WPATH Standards of Care
The WPATH Standards of Care, most recently published in 2022, outlines a series of guidelines which should be met before a patient should be allowed transgender hormone replacement therapy:[37]
- Gender incongruence is marked and sustained
- Patient meets diagnostic criteria for gender incongruence prior to gender-affirming hormone treatment in regions where a diagnosis is necessary to access health care
- Patient has capacity to consent to hormone therapy treatment
- Other possible causes of apparent gender incongruence have been identified and excluded
- Mental health and physical conditions that could negatively impact the outcome of treatment have been assessed
- Understands the effect of gender-affirming hormone treatment on reproduction and they have explored reproductive options
Readiness
Some organizations – but fewer than in the past – require that patients spend a certain period of time living in their desired gender role before starting hormone therapy. This period is sometimes called real-life experience (RLE).
In Sweden, for instance, patients seeking to access gender affirming healthcare must first undergo extended evaluations with psychiatric professionals, during which they must - without any form of medical transition - successfully live for one full year as their desired gender in all professional, social, and personal matters. Gender clinics are recommended to provide patients with wigs and breast prostheses for the endeavor. The evaluation additionally involves, if possible, meetings with family members and/or other individuals close to the patient. Patients may be denied care for any number of "psychosocial dimensions", including their choice of job or their marital status.[42][43]
Transgender and gender non-conforming activists, such as Kate Bornstein, have asserted that RLE is psychologically harmful and is a form of "gatekeeping", effectively barring individuals from transitioning for as long as possible, if not permanently.[44]
In September 2022, the World Professional Association for Transgender Health (WPATH) Standards of Care for the Health of Transgender and Gender Diverse People (SOC) Version 8 were released and removed the requirement of RLE for all gender-affirming treatments, including gender-affirming surgery.[45]
Accessibility
Gender-affirming care is health care that affirms people to live authentically in their genders, no matter the gender they were assigned at birth or the path their gender affirmation (or transition) takes. It allows each person to seek only the changes or medical interventions they desire to affirm their own gender identity, and hormone therapy ("HRT" or gender-affirming hormone therapy) may be a part of that.[46]
Some transgender people choose to self-administer hormone replacement medications, often because doctors have too little experience in this area, or because no doctor is available. Others self-administer because their doctor will not prescribe hormones without an approval letter from a psychotherapist. Many therapists require extended periods of continuous psychotherapy and/or real-life experience before they will write such a letter. Because many individuals must pay for evaluation and care
Access to medication can be poor even where health care is provided free. In a patient survey conducted by the United Kingdom's National Health Service in 2008, 5% of respondents acknowledged resorting to self-medication, and 46% were dissatisfied with the amount of time it took to receive hormone therapy. The report concluded in part: "The NHS must provide a service that is easy to access so that vulnerable patients do not feel forced to turn to DIY remedies such as buying drugs online with all the risks that entails. Patients must be able to access professional help and advice so that they can make informed decisions about their care, whether they wish to take the NHS or private route without putting their health and indeed their lives in danger."[47] Self-administration of hormone replacement medications without medical supervision may have untoward health effects and risks.[48]
A number of private companies have attempted to increase accessibility for hormone replacement medications and help transgender people navigate the complexities of access to treatment.[citation needed]
