Hormonal Therapy: Goals & Assessment - Setting the Stage

Primary Goals:

  • Align physical characteristics with gender identity.
    • Induce affirmed gender's secondary sex characteristics.
    • Suppress natal sex characteristics.
  • Improve mental health & quality of life.
  • Maintain hormone levels in physiologic range of affirmed gender.

Initial Assessment Protocol:

  • Eligibility Criteria:
    • Persistent, well-documented gender dysphoria.
    • Capacity for informed consent.
    • Age of majority (or specific criteria for minors).
    • Address significant co-existing medical/mental health conditions.
  • Baseline Evaluation:
    • Detailed history (medical, surgical, psychiatric).
    • Physical examination.
    • Labs: Hormones (testosterone, estradiol, LH, FSH, prolactin), CBC, LFTs, lipids, HbA1c.
  • Essential Counseling:
    • Realistic outcomes & timeline.
    • Potential risks (e.g., VTE, metabolic changes) & benefits.
    • Crucial: Fertility preservation options before starting hormones.
    • Irreversible vs. reversible effects.
    • Lifelong monitoring necessity.

Feminizing Therapy (AMAB) - Graceful Gendershifting

  • Goal: Induce female secondary sex characteristics (breast growth, fat redistribution); suppress male ones (↓testosterone).
  • Primary Regimens: Estrogen + Anti-androgen.
    • Estrogens:
      • Estradiol: Oral (1-8 mg/day), transdermal patch (50-200 mcg/twice weekly), parenteral.
      • Target serum estradiol: 100-200 pg/mL.
      • ⚠️ Avoid Ethinyl Estradiol (↑ VTE risk).
    • Anti-androgens (Target T <50 ng/dL):
      • Spironolactone: 100-300 mg/day. (📌 Monitor K+!)
      • Cyproterone Acetate (CPA): 10-25 mg/day. (Monitor LFTs, prolactin).
      • GnRH Agonists (e.g., Leuprolide): Most potent, costly.
  • Monitoring: Baseline, then q3 months for 1st yr, then 1-2x/yr. Includes hormones, K+ (spiro), LFTs, prolactin, lipids.
  • Key Effects Timeline:
    • Breast development: 3-6 mo (max 2-3 yrs).
    • Body fat redistribution: 3-6 mo (max 2-5 yrs).
  • Major Risks: VTE (↓ with transdermal estradiol), hyperprolactinemia, gallstones.

⭐ Transdermal estradiol preferred over oral, esp. >40 yrs or VTE risk factors (favorable risk profile). Timeline of physical changes on estrogen HRToka

Masculinizing Therapy (AFAB) - Powering Potency

  • Goal: Induce virilization; suppress menses & female secondary characteristics.
  • Primary Agent: Testosterone.
    • Formulations:
      • Injectable (cypionate, enanthate): IM/SC q 1-4 wks. Common.
      • Transdermal (gel, patch): Daily. Stable levels.
      • Oral (undecanoate): Safer than older oral alkylated androgens.
      • Implants (pellets): Subdermal, long-acting (3-6 months).
  • Key Effects & Onset: 📌 Voice deepening (3-12m, irreversible), Hirsutism (3-6m), Clitoromegaly (3-9m, irreversible), Menstrual cessation (2-6m), Muscle mass ↑, fat redistribution.
  • Monitoring:
    • Baseline: LFTs, lipid profile, Hb/Hct.
    • Regularly: Serum testosterone (aim for male physiologic range; check trough for injectables), estradiol, LFTs, lipids, Hb/Hct.
  • Critical Risks & Management:
    • Erythrocytosis: Monitor Hct (risk >50-54%). Dose ↓ or phlebotomy if needed.
    • Hepatotoxicity: Rare with non-alkylated oral/parenteral forms.
    • Dyslipidemia: Monitor (↑LDL, ↓HDL). Manage PRN.
    • Acne, androgenetic alopecia.
    • Fertility: Counsel on oocyte cryopreservation pre-therapy.

⭐ Target testosterone levels are within the physiologic male range; monitor for erythrocytosis (Hct >52-54% often requires dose adjustment or phlebotomy).

High‑Yield Points - ⚡ Biggest Takeaways

  • Feminizing therapy: Estrogen plus anti-androgens (e.g., spironolactone, GnRH analogs).
  • Masculinizing therapy: Primarily testosterone administration.
  • Goals: Suppress natal hormones; induce desired secondary sexual characteristics.
  • Monitoring: Essential for efficacy, hormone levels, lipids, LFTs, VTE (estrogen), polycythemia (testosterone).
  • Fertility preservation discussion is vital prior to therapy.
  • Note irreversible effects: voice (testosterone), breast development (estrogen).
  • Key contraindications: Hormone-sensitive malignancies, high VTE risk, severe liver disease.
