Background Dysfunctional uterine peristalsis seems to play a pivotal role in hindering embryo implantation among women diagnosed with adenomyosis. This research aims to investigate whether administering an oxytocin receptor antagonist during a frozen embryo transfer (FET) cycle using a hormone replacement therapy (HRT) protocol can enhance in vitro fertilization (IVF) outcomes for infertile women affected by adenomyosis. Methods Between January 2018 and June 2022, our reproductive center conducted IVF-FET HRT cycles for infertile women diagnosed with adenomyosis. Propensity score matching was employed to select matched subjects between the two groups in a 1:1 ratio. Following this, 168 women received an oxytocin receptor antagonist during FET, constituting the study group, while the matched 168 women underwent FET without this antagonist, forming the control group. We conducted comparative analyses of baseline and cycle characteristics between the two groups, along with additional subgroup analyses. Results The study group exhibited notably lower rates of early miscarriage compared to the control group, although there were no significant differences in clinical pregnancy rates, ongoing pregnancy rates, and live birth rates between the two groups. Multivariate analysis revealed a negative correlation between the use of oxytocin receptor antagonists and early miscarriage rates in women with adenomyosis. Subgroup analyses, categorized by age, infertility types, and embryo transfer day, showed a substantial decrease in early miscarriage rates within specific subgroups: women aged ≥ 37 years, those with secondary infertility, and individuals undergoing day 3 embryo transfers in the study group compared to the control group. Furthermore, subgroup analysis based on adenomyosis types indicated significantly higher clinical pregnancy rates, ongoing pregnancy rates and live birth rates in the study group compared to the control group among women with diffuse adenomyosis. Conclusions Administering an oxytocin receptor antagonist during FET may reduce the early miscarriage rates in women with adenomyosis.

Objective To explore the clinical efficacy of commonly used conservative treatments for adenomyosis using both TCM and Western medicine. Methods 210 patients with adenomyosis were selected and divided into 3 groups: Group A (Dan’e Fukang), Group B (Dienogest), and Group C (Goserelin + Mirena), with 70 cases in each group. Afterward, indicators were collected for comparison. Results Different treatment approaches exhibited varying effects on uterine VAS, and PBAC among the 3 groups ( P  < 0.001). The effects of different treatment approaches on serum levels of estradiol (E2), FSH, and CA125 also differed among the 3 groups ( P  < 0.001). After 3 months of treatment, the incidence of adverse reactions among the 3 groups was significantly different ( P  < 0.001), with further comparison indicating a lower incidence of adverse reactions in Groups A and B than in Group C ( P  < 0.017). Meanwhile, statistically significant differences in the incidence of adverse reactions among the 3 groups were observed again after 6 months of treatment ( P  = 0.004), with further comparison revealing a lower incidence of adverse reactions in Group B than in Group C. Additionally, the comparison of uterine volume ( P  < 0.001) and VAS ( P  < 0.001) among the 3 groups was different after 12 months of treatment, and further comparison revealed that the uterine volume was ranked as Group B > Group C > Group A, while the pelvic pain VAS scores were ranked as Group C > Group B = Group A. Conclusion Dan’e Fukang Decoction is markedly effective in alleviating pain; Goserelin + Mirena exhibits significant efficacy in reducing bleeding.

Importance Adenomyosis is a common chronic gynecological disorder, and its treatment is an unmet need. New therapies need to be developed. Mifepristone is being tested for adenomyosis treatment. Objective To determine whether mifepristone is effective and safe for adenomyosis treatment. Design, Setting, and Participants This multicenter, placebo-controlled, double-blind randomized clinical trial was conducted in 10 hospitals in China. In total, 134 patients with adenomyosis pain symptoms were enrolled. Trial enrollment began in May 2018 and was completed in April 2019, and analyses were conducted from October 2019 to February 2020. Interventions Participants were randomized 1:1 to receive mifepristone 10 mg or placebo orally once a day for 12 weeks. Main Outcomes and Measures The primary end point was the change in adenomyosis-associated dysmenorrhea intensity, evaluated by the visual analog scale (VAS) after 12 weeks of treatment. Secondary end points included the change in menstrual blood loss, increased level of hemoglobin in patients with anemia, CA125 level, platelet count, and uterine volume after 12 weeks of treatment. Safety was assessed according to adverse events, vital signs, gynecological examinations, and laboratory evaluations. Results In total, 134 patients with adenomyosis and dysmenorrhea were randomly assigned, and 126 patients were included in the efficacy analysis, including 61 patients (mean [SD] age, 40.2 [4.6] years) randomized to receive mifepristone and 65 patients (mean [SD] age, 41.7 [5.0] years) randomized to received the placebo. The characteristics of the included patients at baseline were similar between groups. The mean (SD) change in VAS score was −6.63 (1.92) in the mifepristone group and −0.95 (1.75) in the placebo group (P < .001). The total remission rates for dysmenorrhea in the mifepristone group were significantly better than those in the placebo group (effective remission: 56 patients [91.8%] vs 15 patients [23.1%]; complete remission: 54 patients [88.5%] vs 4 patients [6.2%]). All the secondary end points showed significant improvements after mifepristone treatment for menstrual blood loss, hemoglobin (mean [SD] change from baseline: 2.13 [1.38] g/dL vs 0.48 [0.97] g/dL;P < .001), CA125 (mean [SD] change from baseline: −62.23 [76.99] U/mL vs 26.89 [118.70] U/mL;P < .001), platelet count (mean [SD] change from baseline: −28.87 [54.30]×103/µL vs 2.06 [41.78]×103/µL;P < .001), and uterine volume (mean [SD] change from baseline: −29.32 [39.34] cm3vs 18.39 [66.46] cm3;P < .001). Safety analysis revealed no significant difference between groups, and no serious adverse events were reported. Conclusions and Relevance This randomized clinical trial showed that mifepristone could be a new option for treating patients with adenomyosis, based on its efficacy and acceptable tolerability.

Background The preservation of fertility and integrity of the reproductive organs has increasingly been of concern to most women with adenomyosis. Adenomyomectomy is conservative surgery that is now widely applied; however, relapse is a serious problem after the operation. Postoperative treatment, such as gonadotropin-releasing hormone agonist (GnRHa) has been suggested to result in reducing the rate of disease recurrence. However, there is still a lack of evidence from randomized clinical trials examining the efficacy of GnRHa in decreasing the postoperative recurrence rate. Method/design Relapse after conservative surgery combined with triptorelin acetate versus conservative surgery only in women with focal adenomyosis is a multicenter, prospective, randomized controlled trial. The primary outcome is relapse assessed using a visual analogue scale (VRS) and numeric rating scale (NRS), pictorial blood loss assessment chart (PBAC) score, and the size of the uterus and the lesion as measured by two/three-dimensional color doppler ultrasonography (2D/3D-CDUS) or magnetic resonance imaging (MRI). The secondary outcomes include quality of life, clinical pregnancy, ovarian reserve, adverse events, assessment by the Short Form (36) Health Survey and Female Sexual Function index, serum follicle-stimulating hormone, estradiol levels, and anti-Muellerian hormone and so on. All these indexes are measured at 3, 6, 12, 18, 24, 30, and 36 months after conservative surgery. Discussion The result of this large, multicenter randomized trial will provide evidence for one of the strategies of long-term management in focal adenomyosis after conservative operation.

Adenomyosis is a clinical condition where endometrial glands are found in the myometrium of the uterus. One in three patients with adenomyosis is asymptomatic, but the rest may present with heavy menstrual bleeding, pelvic pain, or infertility. Heavy menstrual bleeding is the most common symptom. Adenomyosis is distinct from endometriosis (the presence of endometrial glands outside of the uterus), but the two conditions often occur simultaneously. Risk factors for developing adenomyosis include increasing age, parity, and history of uterine procedures. Most patients are diagnosed from 40 to 50 years of age, but younger patients with infertility are increasingly being diagnosed with adenomyosis as imaging modalities improve. Diagnosis of adenomyosis begins with clinical suspicion and is confirmed with transvaginal ultrasonography and pelvic magnetic resonance imaging. Treatment of adenomyosis typically starts with hormonal menstrual suppression. Levonorgestrel-releasing intrauterine systems have shown some effectiveness. Patients with adenomyosis may ultimately have a hysterectomy if symptoms are not controlled with medical therapy.

Abnormal uterine bleeding (AUB) represents a notable sign for benign and malignant uterine pathology. Differentiating adenomyosis from leiomyoma via hysteroscopy aids in selecting appropriate surgical or medical management. Accurate diagnosis is crucial for optimizing fertility outcomes and symptom control. The current study evaluated the diagnostic accuracy of hysteroscopy in differentiating between uterine adenomyosis and leiomymatosis. In addition to; compare between continuous versus intermittent administration of Norethissterone to control both uterine adenomyosis and leiomymatosis. A total of 100 premenopausal women present with AUB. History takin and clinical evaluation was done. All women were subjected to hysteroscopy. Two regimens were used by Norethindrone administration the 1st regimen as continuous manner from day 5 to day 21 46 patients (46%). The 2nd manner was the intermittent type from day 16 and for 10 days 54 patients (54%). Roc-curve of hysteroscopy usage to predict diagnosis; adenomyosis sensitivity was 73.33% and specificity 95.29% and fibroid sensitivity was 73.33% and specificity was 97.65%. Both groups of therapy revealed; highly significant decrease in follow up menorrhagia in continuous Norethindrone group (P < 0.001).By using ROC-curve analysis; Norethindrone administration predicted decreased menorrhagia pain with AUC was 0.973. Hysteroscopy has effective role in differentiating between adenomyosis and fibroids. Yet, long term follows up of abnormal uterine bleeding cases with large sample size in future research are still warranted.

The goal of this study was to examine the efficacy and safety of the levonorgestrel intrauterine system (LNG-IUS) versus dienogest (DNG) in female subjects with symptomatic uterine adenomyosis. This study enrolled 117 women with symptomatic adenomyosis who visited our hospital from May 1, 2019, to June 30, 2022. Participants were randomized to either the LNG-IUS group (n = 48) or the DNG group (n = 79) in an as-controlled clinical trial for 36 months. Visual analog scale (VAS) scores, uterine volume, endometrial thickness, serum carcinoma antigen 125 level, estradiol, follicle-stimulating hormone, luteinizing hormone, and side effects were assessed to compare the efficacy of LNG-IUS and DNG. The VAS pain score was significantly decreased in both groups after 3 months of treatment. Three months later, patients receiving DNG reported significantly lower VAS scores compared with those treated with LNG- IUS (P < 0.05). Compared with LNG-IUS, DNG effectively controlled uterine volume growth after 12 months of treatment but neither significantly reduced uterine volume. During the treatment period, endometrial thickness in both groups was maintained at 0.4 to 0.7 cm. Both DNG and LNG-IUS significantly improved adenomyosis-associated pain after 3 months of treatment. Compared with LNG-IUS, DNG was shown to continuously relieve the symptoms of pain and effectively control the growth of uterine volume.

Adenomyosis, endometriosis of the uterus, is associated with an increased likelihood of abnormal endometrial molecular expressions thought to impair implantation and early embryo development, resulting in disrupted fertility, including the local effects of sex steroid and pituitary hormones, immune responses, inflammatory factors, and neuroangiogenic mediators. In the recent literature, all of the proposed pathogenetic mechanisms of adenomyosis reduce endometrial receptivity and alter the adhesion molecule expression necessary for embryo implantation. The evidence so far has shown that adenomyosis causes lower pregnancy and live birth rates, higher miscarriage rates, as well as adverse obstetric and neonatal outcomes. Both pharmaceutical and surgical treatments for adenomyosis seem to have a positive impact on reproductive outcomes, leading to improved pregnancy and live birth rates. In addition, adenomyosis has negative impacts on reproductive outcomes in patients undergoing assisted reproductive technology. This association appears less significant after patients follow a long gonadotropin-releasing hormone agonist (GnRHa) protocol, which improves implantation rates. The pre-treatment of GnRHa can also be beneficial before engaging in natural conception attempts. This review aims to discover adenomyosis-associated infertility and to provide patient-specific treatment options.

Adenomyosis is characterized by abnormal uterine bleeding, dysmenorrhea and subfertility. Increased expression of angiogenesis markers in adenomyosis presents a treatment opportunity and was studied in an adenomyosis mouse model. Mice were administered tamoxifen (1 mg/kg) on neonatal days 2–5. At six weeks of age, mice received oral treatment with axitinib 3 mg/kg (‘dose I/AX3’, n = 34), axitinib 25 mg/kg (‘dose II/AX25’ n = 34), or with vehicle-only (‘placebo’, n = 34). The prevalence and severity of adenomyosis were assessed. An adenomyosis severity index was calculated by multiplying mean grade/mouse by the percentage affected surface area. Angiogenesis-related gene expression was evaluated using real-time quantitative PCR. 101 mice completed adenomyosis induction and could be analyzed. The prevalence of adenomyosis was 30/33 (90.0%) in dose I, 29/34 (85.3%) in dose II, and 30/34 (88.2%) in placebo treated mice (p = 0.78). High grade (2/3) adenomyosis was significantly less prevalent in mice treated with axitinib dose II (n = 19, 55.9%) than in the placebo group (n = 27, 79.4%, p < 0.05). The adenomyosis severity index was reduced by 48% in the axitinib-treated groups (dose I, p < 0.05). The expression of angiogenic growth factors was reduced in the dose I and II axitinib-treated groups compared to the placebo-treated group. Following these promising first results, further research should focus on commonality among different angiostatic drugs, potential side effects, as well as the method and timing of application.

We aimed to evaluate the successful long-term use of dienogest for the management of pelvic pain and bleeding control in perimenopausal women with symptomatic adenomyosis using real-world data. All women aged ≥ 40 years with adenomyosis who complained of dysmenorrhea and/or menorrhagia and received dienogest between September 2018 and December 2021 were retrospectively recruited. The primary outcome was successful long-term use of dienogest for pelvic pain and/or bleeding control. A total of 87 women were analyzed. Overall, forty-nine (56%) patients had excellent pain control, but 17 (20%) eventually underwent hysterectomy, while 21 (24%) received dienogest for over 24 months (mean 33.5 ± 8.5 months). According to subgroup analysis by age (≥ 45 vs. <45), older women easily discontinued dienogest due to side effects (51% vs. 30%, p  = 0.047) but less frequently changed to surgery (11% vs. 30%, p  = 0.012) than younger women. Older age, higher CA-125 value, and larger uterine size before treatment were linked to poorer long-term responses to dienogest. As risk factor, uterine volume > 352.7 cm 3 reflects easier treatment failure (sensitivity = 65.4%, specificity = 66.7%, area = 0.68, p  = 0.032). In perimenopausal women with symptomatic adenomyosis, nearly half of the treated patients benefitted from dienogest. Our informative findings can assist clinicians in pre-treatment counseling and identifying factors correlated with treatment effectiveness.
