A

terms to describe gender non-conforming or nonbinary persons, based on the directionality of their gender identity.

Q

what do you have to consider before starting HRT?

A
  1. patient readiness and appropriateness
  2. mental health referral
  3. informed consent for ignition of gender-affirming hormone therapy by provider

medical providers who feel comfortable making an assessment and diagnosis of gender dysphoria, as well as assessing for capacity to provide informed consent (understand risks, benefits, alternatives, unknowns, limitations, risks of no treatment) are able to initiate gender- affirming hormones without a prior assessment or referral from a mental health provider

Q

what do you do if the patient has comorbid conditions and wants HRT?

A

the most important step in the initiation of hormonal therapy is to ensure that patients do not have comorbid conditions that could be exacerbated by hormonal treatments.

Q

what do you give to adolescents that want to change?

A

once gender dysphoria is confirmed, pubertal suppression may be accomplished in male and female adolescents with use of a gonadotropin-releasing hormone analogue

this treatment is reversible

Q

what are the evaluations you have to do in an adolescent before initing HRT?

A
  1. menstrual history (if born a female)
  2. tanner staging
  3. height
  4. hormone labs: serum luteinizing hormone, follicle stimulating hormone, estradiol levels, testosterone levels
  5. other labs: CMP, Lipid, HgA1c, bone age and bone density
17
Q

what followup evaluation do you need to do for adolescents on HRT?

A

followup about every 3-6 months and look at:

  1. menstrual cycles (if born a female)
  2. pubertal development/advancement
  3. height

4 hormone labs: serum luteinizing hormone, follicle stimulating hormone, estradiol levels, testosterone levels

  1. other labs: CMP, Lipid, HgA1c, bone age and bone density
18
Q

what’s the difference between initiating HRT in adults vs. adolescents?

A

in adults, hormones are irreversible!!!

HRT results in physiologic changes that irreversible so you need to talk about:

  1. assess readiness
  2. infertility; consider oocyte or sperm cryopreservation
  3. social consequences
19
Q

which HRT do you use for male to female?

A

estrogen and anti-androgen medication

20
Q

what are the risk assoacited with estrogen HRT?1.

A
  1. thromboembolic disease
  2. prolactinoma
    significant liver disease
  3. breast cancer
  4. coronary artery disease
  5. migraine headaches with aura
  6. HTN
  7. liver disease
21
Q

what is the target goal with male to female HRT?

A
  1. decrease testosterone to female range (<55 ng/dL)
  2. maintain an estradiol level similar to premenopausal women (<200 pg/dL)

tell the patient that results that are often noted within 3 months!! they’ll notice:
1. fat redistribution, breast growth, voice and skin changes

  1. decrease in erections, libido, and sperm production
22
Q

what are the estrogen medications give for HRT?

A

estradiol

PO. IM or transdermal

23
Q

what anti-androgen medications can you give for TG females?

A
  1. progesterone or medroxy-progesterone acetate
  2. spironolactone
  3. finasteride
  4. cyproterone
  5. GnRH agonists (ex: leuprolide, histrelin implant)

the transdermal route of estrogen administration is highly recommended, as therapeutic effects are achieved at lower peak doses since first-pass hepatic metabolism is avoided, plasma hormone levels remain constant, and the sustained drug delivery reduces the need for frequent self- administration, which improves patient compliance.

24
Q

what are the risk associated with androgen blockers?

A
  1. hypokalemia

2. hypotension

25
Q

what HRT do you use for TG males?

A

testosterone

can

26
Q

what are the risk associated with testosterone HRT in TG males?

A

patients are at risk for exacerbation of breast or endometrial cancer and significant liver disease while on testosterone therapy

this is because testosterone can be converted into estrogen by aromatase

27
Q

what are the effects of testosterone in TG males? what is the target goal for testosterone HRT?

A

objective of hormonal therapy is to induce virilization with exogenous androgens

testosterone enanthate and testosterone undecanoate are most commonly used = PO, IM, subQ, transdermal

target goal:
1. increase serum testosterone to male range (goal 350-700 ng/dL)

  1. decrease serum estradiol (goal <50 pg per mL)
28
Q

what are the physical results of testosterone in TG males?

A
  1. increased muscle mass
  2. decreased fat mass
  3. increased facial hair and body hair
  4. acne
  5. clitoromegaly
  6. vaginal atrophy
  7. voice deepening
  8. male pattern baldness
  9. increased libido
  10. amenorrhea, especially if it is administered intramuscularly

if this is not achieved, especially in the case of transdermal testosterone administration, progesterone therapy can be used concomitantly to stop menstrual flow

29
Q

what are the risks of testosterone HRT in TG males?

A
  1. polycythemia
  2. hyperlipidemia
  3. HTN
  4. osteoporosis

monitor liver enzymes, Hct lipid levels and screen for DM

must do estradiol monitoring once uterine bleeding ceases

30
Q

how often do you monitor adults that are on HRT?

A

monitor patients every 3 months during the first year of therapy then once or twice yearly thereafter

at these visits, patients are monitored for metabolic alterations resulting from therapy as well as changes in their quality of life

documented side effects from these formulations include depression and increased risk of suicidal thoughts, mood swings, hyperprolactinemia, elevated liver enzymes, migraines, and decreased insulin sensitivity

all of these changes are important to monitor as they can significantly impair the health of these patients
