INFORMED CONSENT for HORMONE TREATMENT - Oestrogen
For treatment of Gender Dysphoria
Patient Label
I have been assessed by a psychiatrist and have a formal diagnosis of gender dysphoria.
I agree that I have had the implications of having oestrogen therapy (in conjunction with
medication to reduce the production of testosterone – delete if not applicable) explained to me in
full by ……………………………….. (Name of clinician).
Effects of Oestrogen
I have gender dysphoria and therefore will be treated with oestrogen. As a result of taking
oestrogen I expect to experience: some breast growth; some redistribution of body fat to
approximate to a female pattern; decreased upper body strength; softening of skin; decrease in
body hair; a slowing of the loss of scalp hair; decreased fertility and testicular size and less
frequent, less firm erections. Some of these changes are reversible, but breast enlargement,
which will occur slowly over a period of up to two years, will not completely reverse after
treatment is discontinued. The degree of change is unpredictable and may not fulfil my
expectations.
In the longer term, the size of my genitalia will be reduced. I may become permanently infertile
after prolonged treatment. I have been given specific information regarding local fertility services.
I understand that if I have not made use of those facilities before treatment is undertaken, I may
be unable to do so later through irreversible infertility.
I understand that the changes outlined above will start shortly after treatment is initiated, but that
the full physical impact of taking hormones may not be evident until several years of continuous
treatment have been undergone.
I have had the opportunity to discuss, with my clinician, the effects of the proposed medication
and any side effects I may experience, and to clarify any points I did not understand.
Potential Risks and Negative Side Effects
• I understand that the most likely side effects are: venous thrombosis; pulmonary
embolism; benign pituitary prolactinoma (non-malignant tumour in the brain); weight gain;
mood swings; liver disease; gallstones; breast cancer; high blood pressure and diabetes
mellitus.
• I understand that I will be at increased risk of unwanted side effects if any of the following
pre-existing factors apply: cigarette smoking; obesity; alcohol and/or drug misuse and
advanced age.
• I understand that, after genital surgery, a lifelong maintenance dose of oestrogen is
almost certain to be required to maintain feminisation and protect against osteoporosis.
• I understand that any surgical procedures will require further psychiatric evaluation.
• I agree to take the hormones in the dosage prescribed by my clinician and undertake not
to take additional doses of oestrogen as this will pose an extra health risk.
• I understand that other medication available on or off prescription may be contra-
indicated whilst I am on hormone medication.
Appendix one - Document 3
•
I agree to my hormone treatment being monitored by my clinician. I understand that
physical examinations and blood tests are needed on a regular basis to check for
negative side-effects of feminizing medication.
•
I understand that I may be discharged to my GP for long term monitoring when deemed
appropriate by my clinician
•
I agree to ongoing psychiatric support as advised/necessary.

I am over 16 years old.

INFORMED CONSENT for HORMONE TREATMENT - Testosterone
For treatment of Gender Dysphoria
Patient Label
I have been assessed by a psychiatrist and have a formal diagnosis of gender dysphoria.
I agree that I have had the implications of testosterone administration explained to me in full by
……………………………(name of clinician).
Effects of Hormones
Have gender dysphoria and therefore will be treated with testosterone. I understand that I can
expect the following permanent changes: a deepening of the voice; clitoral enlargement;
possibly mild breast atrophy; increased facial and body hair and male pattern baldness.
The following changes are reversible: increased upper body strength; weight gain; increased
sexual arousability; and decreased hip fat. Cessation of menstruation, which normally
accompanies cross-hormone administration, may or may not be reversed if hormones are
ceased.
I understand that reproductive capacity will eventually be lost after treatment, although this may
take several years. I have been fully informed of the options to enable me to have a genetically
related child and having been given specific information regarding local fertility facilities. I
understand that if I have not made use of these facilities before treatment is undertaken, I will be
unlikely to be able to do so later.
I understand that the changes outlined above will start shortly after treatment is initiated, but that
the full physical impact of taking hormones may not be evident until several years of continuous
treatment have been undergone.
Potential Risks and Negative Side Effects
•
I understand that treatment with testosterone may cause the following side effects: acne,
mood swings, increased risk of cardiovascular disease heart and polycythaemia; rarely,
malignant liver tumours and/or liver dysfunction; in the longer term, skin atrophy in the
genital area may be experienced.
•
I understand that I will be at increased risk of unwanted side effects if any of the following
pre-existing factors apply: cigarette smoking; obesity; alcohol and/or drug misuse;
advanced age; high blood pressure; clotting abnormalities; cancer; endocrine
abnormalities.
•
I understand that, in the light of current knowledge and practice, an oophorectomy
(removal of ovaries) and hysterectomy (removal of uterus and cervix) may be
recommended after about five years of testosterone therapy. I understand that if these
are not undertaken then regular cervical smears are recommended because of the
increased risk of cancer.
•
I understand that any surgical procedures will require further psychiatric evaluation.
•
I understand that a lifelong maintenance dose of testosterone is likely to be required,
although a reduction in the dosage will be considered for health reasons after removal of
the ovaries.
Appendix one - Document 4
•
I understand that if I stop taking testosterone, there is a risk of developing osteoporosis
unless oestrogen therapy is undertaken. I understand that oestrogen therapy, itself, can
produce unwanted medical and physical side effects.
•
I agree to take the hormones in the dosage prescribed by my clinician and undertake not
to take additional doses of testosterone as this will pose an extra health risk.
•
I agree to my hormone treatment being monitored by my clinician. I understand that
physical examinations and blood tests are needed on a regular basis to check for
negative side-effects of masculinizing medication.

appropriate by my clinician.
