February 2026 in “Cureus” In this case report, a 25-year-old transgender woman on testosterone-blocking therapy developed generalised hypertrichosis after starting ciclosporin for severe plaque psoriasis, illustrating that ciclosporin can induce this side effect even under androgen suppression.
October 2024 in “Journal of the Endocrine Society” In this retrospective chart review, researchers observed that estrogen monotherapy effectively suppressed testosterone levels below 50ng/dL in all transfeminine patients studied, particularly those using injectable formulations, though the small sample size and ongoing data collection limit these findings.
October 2024 in “Journal of the Endocrine Society” In this retrospective study, among transfeminine patients aged 19-81 receiving gender-affirming estrogen therapy, 100% achieved testosterone suppression without anti-androgens when serum estradiol exceeded 100pg/mL, predominantly using injectable estrogen.
