Efficacy and Safety of Hormonal Therapies for Acne: A Narrative Review. (PubMed, Clin Cosmet Investig Dermatol) - "Eligible articles included randomized controlled trials, cohort studies, systematic reviews, and meta-analyses evaluating hormonal therapies such as combined oral contraceptives (COCs), spironolactone, cyproterone acetate, and topical antiandrogens (eg, clascoterone)...Hormonal therapies are effective and well-tolerated options for acne, particularly in women with hormonal patterns or refractory disease. By specifically targeting androgen-driven pathways, hormonal agents offer sustained improvement and should be incorporated into personalized acne management."

Impact of Growth-promoting Therapies on Puberty, Growth, and Final Height in Classical 21-hydroxylase Deficiency. (PubMed, J Clin Endocrinol Metab) - "Patients with 21-OHD had diminished FH despite early diagnosis. Puberty in classical 21-OHD had an earlier onset, slower tempo, and prolonged duration, especially in girls, in which GPTs are less effective in promoting height. The management of pubertal growth needs a personalized approach in patients with classical 21-OHD."

Cyproterone acetate for hirsutism. (PubMed, Cochrane Database Syst Rev) - "There were some differences in clinical outcome between CPA and spironolactone, CPA and flutamide, and CPA and finasteride. There were no clinical differences between CPA and the other medical therapies, possibly because of small study size, lack of standardised assessment and objective determinants of improvement in many studies. There are insufficient data presented to compare the adverse effects of all the treatment options. Larger, carefully designed studies are needed to compare efficacy and safety profiles between the therapeutic options available."

Delayed regression of atypical meningiomatosis following discontinuation of gender-affirming hormone therapy in a transgender woman: a case report. (PubMed, Br J Neurosurg) - "Cyproterone acetate (CPA) is an antiandrogen that may be used in combination with estradiol in gender reaffirmation therapy...However, its effect appears to be delayed, indicating that cessation alone is suboptimal in cases causing significant mass effect and symptomatology. In such cases, early surgical intervention should be considered."

Impact of gender-affirming hormone therapy on spermatogenesis: analysis of testicular histological specimens. (PubMed, Hum Reprod) - "These findings provide clinically relevant insights for fertility counseling in TGD individuals, emphasizing that CPA and progesterone significantly impair spermatogenesis, whereas spironolactone may allow for greater preservation of sperm maturation. This has implications for fertility preservation discussions prior to GAHT initiation and may inform individualized hormone regimen selection based on reproductive goals."

Carboxyl-PEG modified Fe3O4 nanoparticles as an ultrasensitive SERS substrate for multiplex detection of exogenous hormones related to endometrial cancer. (PubMed, Methods) - "This approach successfully enabled ultrasensitive detection and precise discrimination of multiple typical exogenous hormonal drugs, including tamoxifen, drospirenone, cyproterone acetate, medroxyprogesterone acetate, estradiol ester derivatives, and dydrogesterone. In matrix-spiked serum and urine samples, which mimic complex biological matrices validations, the AI-SERS platform demonstrated exceptional performance in the identification and quantitative analysis of target exogenous hormones. This research provides an intelligent analytical strategy for rapid and highly sensitive detection of multiple trace exogenous hormones in complex matrices."

Plasma proteome adaptations during feminizing gender-affirming hormone therapy. (PubMed, Nat Med) - "Here we examined plasma proteome changes over 6 months of feminizing GAHT in 40 transgender individuals treated with estradiol plus one of two antiandrogens: cyproterone acetate or spironolactone. Feminizing GAHT skewed the protein profile toward that linked to asthma and autoimmunity, while GAHT with cyproterone specifically skewed it away from an atherosclerosis-associated profile, suggesting a protective effect. These results reveal that feminizing GAHT reshapes the plasma proteome in a hormone-dependent manner, with implications for reproductive capacity, immune regulation and long-term health outcomes."

THE NAPCSR, THE BIOMARKER FOR CHC-ASSOCIATED THROMBOTIC RISK EVALUATION (FIGO 2025) - " nAPCsr was assessed on plasma samples from women using either no contraception (n = 220), progestin-only pill (POP) (n = 14), natural estrogen (estradiol or estetrol)-based CHC (n = 43), ethinylestradiol (EE) 20 or 30 μg with levonorgestrel (n = 70), EE 20 μg with desogestrel, gestodene or drospirenone (n = 105) and EE ≥30 μg with desogestrel, dienogest or cyproterone acetate (n = 32). For non-users or women using POP, nAPCsr >3.0 indicate a procoagulable state, which could be attributable to thrombophilia (e.g. FV Leiden), meaning the pill should be contraindicated. For women already on CHCs, nAPCsr above respective thresholds indicate that the benefit–risk balance of the contraceptive formulation used is questionable."

Androgenetic alopecia in the transgender population: experience in a public hospital in Latin America (EADV 2025) - "Among TW, 75% (3/4) were on hormone therapy with varying regimens of estrogens, cyproterone, and spironolactone...The NB patient received topical 5% minoxidil without hormone therapy...Finasteride and dutasteride are safe options for both groups; dutasteride is preferred after finasteride failure... AGA is a common finding in TM and NB individuals on testosterone, typically developing 2–5 years after hormone initiation. In TW, hormone therapy may slow the progression of androgenetic alopecia; however, hair regrowth is uncommon, and specific therapeutic interventions are often required. Most therapeutic strategies are based on cisgender guidelines due to limited trans-specific research."

A series of 510 cases of hypertrichosis in women: Epidemioclinical profile, proposed treatments, and psychosocial repercussions (EADV 2025) - "Furthermore, 5.9% of the women had received medical treatment for hypertrichosis, with anti-androgens such as cyproterone acetate being the most prescribed (69.5%)... Our findings indicate a high prevalence of hypertrichosis among young women, a result that is not surprising and aligns with existing literature, particularly for those with hormonal disorders such as acne and PCOS. Current treatment options, do not always yield satisfactory results for all patients, necessitating a more personalized and multidisciplinary approach. Hair removal methods remain the most commonly used solutions, but their perceived effectiveness is limited."
