Delving into the Latest Updates on Dydrogesterone with Synapse

This cross-sectional study aims to compare the effectiveness of oral contraceptives, oral progesterone (didrogesterone), and inositol in regulating menstrual cycles among women diagnosed with polycystic ovary syndrome (PCOS).
PCOS is a common endocrine disorder affecting reproductive-aged women and is associated with menstrual irregularities, hyperandrogenism, and polycystic ovarian morphology. While oral contraceptives are the mainstay of treatment, their use may be contraindicated in patients with cardiovascular risk factors, liver dysfunction, or in those who desire pregnancy.
This study investigates whether oral progesterone and myo-inositol can serve as effective and safer alternatives for menstrual regulation and improvement of ovarian morphology and hyperandrogenic symptoms.
A total of 150 women aged 15-40 years with a diagnosis of PCOS will be enrolled and divided into three equal groups:
Group 1: Oral contraceptive users
Group 2: Oral progesterone users
Group 3: Inositol users The study will assess changes in menstrual regularity, ovarian morphology (via ultrasound), and clinical features such as hirsutism and acne before and after treatment.

Dydrogesterone versus levonorgestrel-releasing intrauterine system for abnormal uterine bleeding: a propensity score-matched analysis of long-term efficacy and recurrence

Article

Author: Wei, Xiaoli ; Huang, Li ; Li, Xiangzun

OBJECTIVE:

To compare dydrogesterone versus levonorgestrel-releasing intrauterine system (LNG-IUS) for abnormal uterine bleeding (AUB) management with long-term follow-up and etiology-stratified analysis.

METHODS:

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.

Network meta-analysis of progestogen administration routes for luteal phase support in fresh embryo transfer IVF cycles

Review

Author: Manipalviratn, Somjate ; Griesinger, Georg ; Kahler, Elke ; Li, Rose ; Murdia, Kshitiz ; Wang, Qian ; Pabuccu, Emre ; Labarta, Elena

The route of administration significantly influences the pharmacokinetics of progestogens. For luteal phase support (LPS) after fresh embryo transfer in IVF, ESHRE recommends vaginal, intramuscular, subcutaneous progesterone or oral dydrogesterone. This network meta-analysis evaluated the relative effectiveness of progestogen administration routes on clinical pregnancy rate (CPR) and live birth rate (LBR) in fresh IVF cycles. A systematic review identified peer-reviewed, published randomized controlled trials (RCTs) comparing individual progestogens (versus placebo or other progestogens) and reporting CPR. Studies involving frozen-thawed transfers, non-progestogenic LPS or non-available formulations were excluded. Of the 24 RCTs included, oral administration was the only route reaching statistical significance for increased CPR, although overlapping confidence intervals across comparisons indicate uncertainty in clinically relevant superiority. For LBR, only oral and intramuscular routes demonstrated statistically significant improvement versus placebo; vaginal and subcutaneous did not. These findings, supported by sensitivity analyses excluding low-quality and older studies, suggest that oral and intramuscular progestogens may be more effective in improving IVF outcomes, but outcome differences require further studies. This study substantially advances the evidence base by integrating recent data, applying rigorous quality assessment standards and using state-of-the-art network meta-analytic methodology, contributing to refining recommendations for optimal progestogenic LPS in fresh IVF cycles.

Impact of Follicle Size at Trigger on Reproductive Outcomes in Letrozole-Modified Natural Frozen Embryo Transfer Cycles in High Responder Patients

Article

Author: Ucar, Ugras ; Pabuccu, Recai ; Blockeel, Christophe ; Pabuccu, Emre

PURPOSE:

To evaluate whether follicle size at hCG trigger influences reproductive outcomes in letrozole-modified natural frozen embryo transfer (let-mNC-FET) cycles among high-responder patients.

METHODS:

This observational cohort included 170 let-mNC-FET cycles. Patients were stratified by follicle-size percentiles at trigger: 0-25th (15-17 mm; n = 43), 25-75th (18-20 mm; n = 90), and > 75th (21-24 mm; n = 37). Oral dydrogesterone provided luteal support. Serum progesterone (P4) on embryo-transfer (ET) day was measured with an assay that does not detect dydrogesterone (reflecting endogenous luteal production). The primary outcome was the ongoing pregnancy rate (OPR). Group comparisons used ANOVA/Kruskal-Wallis and χ² tests; predictors of OPR were evaluated with logistic regression.

RESULTS:

Positive hCG and OPR did not differ across percentile groups (51.2%, 52.2%, 55.6%; p = 0.920 and 48.8%, 50.0%, 52.7%; p = 0.833, respectively). Endometrial thickness at trigger differed by group (medians 8.0, 9.0, 7.8 mm; p < 0.001), while ET-day P4 increased with larger follicles (medians 19.74, 21.00, 26.50 ng/mL; p = 0.001; post-hoc 0-25th vs > 75th p = 0.0009). In multivariable analysis, younger age (aOR 0.834; 95% CI 0.762-0.914; p = 0.0001), higher BMI (aOR 1.169; 1.015-1.346; p = 0.0303), fewer stimulation days (aOR 0.798; 0.647-0.983; p = 0.0343), larger leading follicle size (aOR 1.343; 1.059-1.703; p = 0.0151), and higher ET-day P4 (aOR 1.067; 1.027-1.108; p = 0.0007) independently predicted OPR; EMT and AMH were not associated (p ≥ 0.08 and p = 0.25).

CONCLUSIONS:

Although OPR did not differ across follicle-size strata, larger follicle size at trigger and higher endogenous luteal P4 were independent predictors of OPR in highresponders. Confirmation in adequately powered prospective studies is warranted.
