NCT07628660
Endometrial sampling is a commonly performed gynecological procedure used for the diagnosis of abnormal uterine bleeding and endometrial abnormalities. Different anesthetic techniques may be used during the procedure, including sedo-analgesia and local anesthesia. The purpose of this prospective observational study is to evaluate whether the anesthetic technique used during endometrial sampling affects female sexual function one month after the procedure. Female sexual function will be assessed using the validated Female Sexual Function Index (FSFI) questionnaire. A total of 210 women undergoing endometrial sampling at Prof. Dr. Cemil Taşcıoğlu City Hospital will be enrolled. Participants will be assigned to groups according to the anesthetic technique used during their routine clinical care. FSFI scores obtained at the one-month follow-up visit will be compared between women who underwent the procedure under sedo-analgesia and those who received local anesthesia. Secondary analyses will include comparison of FSFI scores according to symptom status and histopathological diagnosis. The findings of this study may contribute to a better understanding of the impact of anesthetic techniques on postoperative sexual health and quality of life in women undergoing gynecological procedures.

NCT07608068
This study aims to prospectively collect breast MRE and vMRE image data, clinical data, and pathological data from female patients due to breast lesions indicated by mammography or ultrasound with BI-RADS category 4 or above. It evaluates the consistency of MRE and vMRE in measuring breast lesions and compares the diagnostic performance of the two methods in distinguishing between benign and malignant breast conditions, with the goal of determining whether vMRE has the potential to replace or supplement MRE. Furthermore, it explores and compares the correlation and diagnostic efficacy of sADC and virtual shear modulus calculated at different b-values with the true shear modulus, aiming to identify and optimize the optimal imaging protocol suitable for breast imaging. It also investigates the correlation between quantitative parameters of vMRE and MRE and pathological results such as patient pathological grading and molecular typing, providing imaging evidence for individualized precision assessment.
NCT07455773
Endometrial receptivity is a key determinant of success in assisted reproductive technology (ART). A significant proportion of patients experience repeated implantation failure despite euploid embryos and adequate laboratory conditions. Thin endometrium, often defined as ultrasound-measured thickness \<7 mm at embryo transfer, is frequently refractory to estrogen therapy and associated with low implantation and clinical pregnancy rates. Platelet-Rich Plasma (PRP), obtained from autologous blood by double centrifugation, is rich in growth factors capable of stimulating cell proliferation, angiogenesis, and tissue regeneration, suggesting potential benefits for endometrial function. Preliminary studies indicate improved endometrial thickness and reproductive outcomes following intrauterine PRP infusion, but standardized protocols and systematic data are lacking. The PMA\_PREPAIRE study is a prospective, single-center, controlled, non-randomized interventional clinical trial conducted at the Reproductive Medicine Center of Cardinal Massaia Hospital, Asti. The study aims to evaluate the efficacy and safety of intrauterine infusion of autologous platelet-rich plasma (PRP), in association with hormone replacement therapy (HRT), in improving endometrial receptivity and reproductive outcomes in women with thin or refractory endometrium. The study includes a prospective control group treated with standard HRT alone. Eligible women will be treated with standard clinical care, with PRP infusion offered to those with insufficient response to HRT. Inclusion criteria include age 18-45, BMI 18-30 kg/m², history of ≥1 failed embryo transfer, EMT \<5 mm after ≥10 days of HRT, and normal routine lab tests. Exclusion criteria include endometrial disease, recent gynecological infection, and systemic conditions such as thrombocytopenia or coagulopathies. Procedures include standard HRT from cycle days 1-2, serial ultrasound monitoring of endometrial thickness from days 6-8, intrauterine PRP infusion if EMT ≤7 mm (up to three infusions per cycle), embryo transfer once EMT ≥7 mm, and follow-up through pregnancy testing and confirmatory ultrasound. Collected data will be analyzed using descriptive statistics, paired and unpaired comparative analyses, and multivariate logistic regression models to evaluate predictors of treatment response and reproductive outcomes (significance level p \< 0.05). A sample size of 34 patients per group was estimated to detect a 1.5 mm difference in endometrial thickness (EMT) with 90% statistical power. Considering an anticipated dropout rate of 15%, a total of 40 patients per group will be enrolled. The study includes: an intervention group consisting of 40 patients treated with HRT plus intrauterine PRP infusion; a prospective control group consisting of 40 patients with refractory thin endometrium treated with standard HRT alone, without PRP.
NCT07404969
The goal of this clinical trial is to determine whether telomere profiling and other biological aging hallmarks can help identify underlying mechanisms of persistent infertility in women with post-treatment unexplained infertility. The study also evaluates whether a personalized integrative treatment guided by these biomarkers can improve reproductive outcomes. The study includes women aged 25 to 42 years who continue to experience infertility despite appropriate management of identifiable reproductive conditions and repeated attempts with assisted reproductive technologies (ART), such as intrauterine insemination (IUI) or in vitro fertilization (IVF). The main questions this study aims to answer are: * Can telomere and biological aging hallmarks profiling identify a biological aging phenotype associated with infertility? * Can an integrative treatment guided by these profiles improve clinical pregnancy outcomes? Participants will: * Undergo a baseline reproductive evaluation and blood-based assessment of telomeres and aging hallmarks. * Receive an integrative approach combining Traditional Chinese Medicine (TCM), targeted nutritional support, and standard fertility care. * Proceed with natural conception attempts or standard assisted reproductive technologies following the preconception phase. * Participants will be followed to assess pregnancy outcomes and changes in biological aging hallmarks.
NCT07403994
Pregnancy is a period associated with significant hormonal, physical, and emotional changes that may affect a woman's sexual function and increase sexual distress. Sexual dysfunction and related distress are common during pregnancy and may negatively impact quality of life and intimate relationships. Regular physical activity during pregnancy has been shown to improve physical well-being, emotional health, and overall quality of life. Prenatal Pilates is a commonly preferred exercise method among pregnant women and is thought to improve posture, pelvic floor muscle strength, body awareness, and stress levels. However, limited evidence exists regarding the effects of prenatal Pilates on female sexual function and sexual distress during pregnancy. This prospective observational cohort study aims to evaluate changes in female sexual function and sexual distress throughout pregnancy and to compare these changes between pregnant women who regularly participate in instructor-led prenatal Pilates and those who do not engage in structured exercise. Participants will be enrolled during the first trimester and followed across all three trimesters of pregnancy. Female sexual function will be assessed using the Female Sexual Function Index (FSFI), and sexual distress will be measured using the Female Sexual Distress Scale-Revised (FSDS-R). These questionnaires will be administered online during the first, second, and third trimesters. The study does not involve any intervention or exercise prescription; participants in the Pilates group will continue their usual prenatal Pilates activities by personal choice. The results of this study are expected to contribute to a better understanding of the relationship between prenatal physical activity and sexual health during pregnancy and may help inform future counseling and supportive care strategies for pregnant women.

The GYNAB study aims to compare patient satisfaction and clinical outcomes between dematerialized post-emergency gynecological follow-up using a connected health app and traditional in-person follow-up. Conducted by Drs. Laëtitia CAMPIN and Louis MARCELLIN at Hôpital Cochin, it is sponsored by Assistance Publique - Hôpitaux de Paris. The main objective is to assess patient satisfaction at day 7 on a scale from 0 to 10, considering symptom management, follow-up quality, and task performance. Secondary objectives include comparing satisfaction at day 28, PROM-ED scores for symptom relief, understanding, reassurance, and care planning at days 7 and 28, hospitalization rates, unscheduled consultations, surgical interventions, total hospital time by day 28, and physician satisfaction at 28 days. This randomized trial involves women aged 18-60 needing follow-up for conditions like genital infections, non-complicated ectopic pregnancies, unlocated pregnancy, first trimester metrorrhagia, miscarriages , and severe vomiting before 12 weeks. Inclusion criteria are women aged 18-60 needing specified follow-up. Exclusion criteria are severe clinical intolerance, severe criteria ultrasound findings, non-French speakers, and inability to use digital applications. The intervention group uses a connected health app for data collection and communication, logging symptoms and test results, with medical team notifications for urgent updates. The control group receives traditional in-person follow-up with scheduled consultations and emergency contact information. The study hypothesizes that digital follow-up will improve patient experience, reduce hospital visits, and provide comparable or superior satisfaction and clinical outcomes. The results could promote broader digital health adoption in various medical fields.
NCT07541742
This study aims to examine how societal and climate changes influence the nutritional status and fish consumption of young women over a 10 year period in southern Bangladesh, and how these factors affect their children's health. A cohort of 240 adolescents first studied in 2017 will be followed to assess changes in their dietary patterns, nutritional status, climate perceptions and mitigation practices, as well as the nutritional status of their children aged 6 months to 5 years. The study in 2017 sampled 60 adolescent girls in each of four rural communities, plus a semi-rural community around a fish processing plant, representing in total 5 communities. Of these 60 X 5 = 300 girls, the current study follows up the individuals in the rural communities representing a cohort of 240. Bangladesh faces high rates of adolescent malnutrition, with many girls married before 18 and suffering from chronic nutrient deficiencies. These issues have long-term impacts on health, productivity, and intergenerational well-being. By linking the fisheries and aquaculture sector, a key to Bangladesh's economy with public health and nutrition, this research aims to guide targeted policies for vulnerable coastal communities.
