This single-center retrospective cohort study analyzed reproductive-aged women with International Federation of Gynecology and Obstetrics (FIGO)-classified AUB receiving dydrogesterone (n = 131) or LNG-IUS (n = 118). Propensity score matching balanced baseline covariates between groups (n = 104 pairs). Primary outcomes were bleeding control rates (composite: hemoglobin increase ≥ 1.5 g/dL, ≥ 50% Pictorial Blood Loss Assessment Chart [PBAC] reduction, no rescue interventions) at 3 and 12 months. Secondary outcomes included 24-month recurrence and adverse events (AEs).

RESULTS:

LNG-IUS demonstrated superior 3-month bleeding control versus dydrogesterone (82.7% vs. 65.4%; relative risk [RR] 1.26, 95% confidence interval [CI] 1.08-1.48; p = 0.002). At 12 months, bleeding control rates were comparable between groups (78.8% vs. 72.1%; RR 1.09, 95% CI 0.96-1.24; p = 0.17). LNG-IUS significantly reduced 24-month recurrence risk (hazard ratio [HR] 0.48, 95% CI 0.32-0.72; p < 0.001), particularly for structural AUB (HR 0.39, 95% CI 0.24-0.64). Subgroup analysis revealed LNG-IUS superiority in adenomyosis at 12 months (88.2% vs. 60.0%; RR 1.47, 95% CI 1.24-1.74; p < 0.001) but comparable efficacy in nonstructural AUB (76.6% vs. 72.9%; RR 0.95, 95% CI 0.78-1.16; p = 0.63). Dydrogesterone exhibited higher systemic AEs (28.2% vs. 13.6%; p = 0.003), while LNG-IUS had device-related events including expulsion (5.1%).

CONCLUSION:

LNG-IUS offers superior short-term bleeding control and sustained long-term recurrence prevention, especially for structural AUB. Dydrogesterone effectively manages nonstructural etiologies but carries higher systemic adverse event rates. Treatment selection should be etiology-guided, balancing immediate symptom control versus recurrence prevention and individualized safety considerations.

Dydrogesterone and inflammatory marker regulation: a systematic review and quantitative meta-analysis

Review

Author: Valenti, Vitor E. ; Martineli, Rafaela P. ; Soares Junior, José Maria ; Raimundo, Rodrigo D. ; Candeloro, Bruno M. ; Chedraui, Peter ; Brito, Giovanna J. ; Zangirolami-Raimundo, Juliana

OBJECTIVE:

To evaluate the effects of dydrogesterone on systemic inflammatory biomarkers in women across different reproductive and hormonal clinical contexts compared with placebo or other pharmacological interventions.

METHODS:

This systematic review and meta-analysis followed PRISMA guidelines and was registered in PROSPERO (CRD420251163959). Searches covered database inception through December 2025. Randomised controlled trials and controlled studies reporting IL-6, IL-10, TNF-α, or C-reactive protein were included. Quantitative synthesis used a random-effects model. Risk of bias and certainty of evidence were assessed using Cochrane and GRADE tools.

RESULTS:

Seven studies were included. No statistically significant effects were found for IL-6 (mean difference [MD], -0.15 pg/mL; 95% CI, -0.67 to 0.38; p = 0.58), IL-10 (MD, 2.39 pg/mL; 95% CI, -2.08 to 6.86; p = 0.29), TNF-α (MD, 0.06 pg/mL; 95% CI, -0.09 to 0.22; p = 0.42), or C-reactive protein (MD, 0.08 mg/L; 95% CI, -0.25 to 0.40; p = 0.65). Heterogeneity was very high for IL-10 and moderate for IL-6 and TNF-α. Most studies had high risk of bias; certainty was very low for all biomarkers.

CONCLUSION:

Dydrogesterone did not significantly alter systemic inflammatory biomarkers. Evidence does not indicate increased inflammation, but certainty is very low. Larger, well-designed randomised controlled trials are needed to clarify its immunomodulatory effects.

Menopause Hormone Therapy in Women With Cardiovascular Risk Factors or Established Ischemic Heart Disease: A Joint FIGO and WHF Position Paper

Review

Author: Khadilkar, Suvarna S ; Poppas, Athena ; Maas, Angela H E M ; Frezet, Federica ; Divakar, Hema ; Gulati, Martha ; Benedetto, Chiara ; de Oliveira, Gláucia Maria Moraes ; Genazzani, Andrea R

Extending women's health-span is a key challenge for the medical community. Although women live longer than men, they face a higher burden of chronic diseases, such as cardiovascular diseases (CVDs) and disabilities. Endogenous estrogens appear to benefit cardiovascular health, and their marked decline at menopause is associated with increased cardiovascular risk; conversely, poor cardiovascular health may hasten menopause onset. Systemic menopause hormone therapy (MHT) begun early-ideally soon after symptom onset and at most within 10 years of the final menstrual period-alleviates climacteric symptoms and is associated with long-term benefits. This joint position paper between the International Federation of Gynecology and Obstetrics (FIGO) and the World Heart Federation (WHF) aims at supporting both gynecologists and cardiologists in providing a tailored and evidence-based counseling on systemic MHT use to women with increased CVD risk or established ischemic heart disease (IHD). Women with CVD risk factors require thorough risk stratification to tailor MHT type, dose, and route. For those at high thromboembolic risk, transdermal estrogen, with micronized progesterone or dydrogesterone when needed, is considered the safest regimen. Women with established IHD may receive systemic MHT for symptom relief, provided risks and benefits are carefully reviewed. Transdermal low-dose estrogen, alone or with micronized progesterone or dydrogesterone, is the best choice. All primary and secondary prevention measures, including statins, should be continued. Managing the most complex cases warrants the adoption of a multidisciplinary approach between cardiologists, gynecologists, internists and primary care providers to offer the best possible care.
