Methods and Guidelines for Both Transgender Women and Transgender Men

For Transgender Women (MTF)

Administration Methods:

1. Oral Estrogen: Oral conjugated estrogens or 17-beta estradiol are common forms, with dosages ranging from 2–6mg/day[2].

2. Parenteral Estrogen: This includes estradiol valerate or cypionate injections, with dosages of 5–20mg intramuscularly (i.m.) every two weeks or 2–10mg i.m. weekly[2].

3. Transdermal Estrogen: Estradiol patches are applied, with dosages ranging from 0.1–0.4mg twice a week[2].

4. Anti-Androgens: Spironolactone (100–200mg/day, up to 400mg) or cyproterone acetate (50–100mg/day) are used to block testosterone effects. GnRH agonists may also be used[2].

Dosage and Monitoring:

Estrogen therapy aims to achieve serum estradiol levels in the female range (testosterone <30 ng/dl, E2 <200 pg/ml) while monitoring for feminizing and adverse effects every 3–6 months during the first year, then every 6–12 months[2].

Monitoring should include serum testosterone and estradiol levels, prolactin, triglycerides, and potassium levels if taking spironolactone[2].

For Transgender Men (FTM)

Administration Methods:

1. Oral Testosterone: Testosterone undecanoate is taken orally, with dosages of 160–240mg/day[2].

2. Parenteral Testosterone: Testosterone enanthate or cypionate injections are administered with dosages of 50–200mg/week or 100–200mg every two weeks. Testosterone undecanoate injections are another option, with a dosage of 1000mg every 12 weeks[2].

3. Transdermal Testosterone: Testosterone gel (1%) is applied daily with dosages of 2.5–10g/day, and testosterone patches are used with dosages of 2.5–7.5mg/day[2].

Dosage and Monitoring:

The goal for transgender men is to increase testosterone levels to the normal male range (300–1000 ng/dl) while monitoring for virilizing and adverse effects every 3–6 months during the first year, then every 6–12 months[2].

Monitoring should include serum testosterone levels, hematocrit, lipid profile, and bone mineral density (BMD) screening for patients at risk for osteoporosis[2].

General Considerations

- Informed Consent: Before starting HRT, patients should undergo a thorough psychosocial assessment and provide informed consent[4].

- Individualized Treatment: The choice of HRT regimen should be tailored to each individual's medical history, goals, and preferences[6].

- Health Monitoring: Regular monitoring is crucial to adjust dosages and ensure the safety and effectiveness of the therapy[2][4].

This overview highlights the importance of personalized care and regular monitoring in the administration and dosage of hormone replacement therapy for gender-affirming care.
