By doing so, the potential of using shear wave elastography to diagnose and predict outcomes for patients seeking fertility treatment might be established.
NCT07622420
In the past two decades, the evidence-based knowledge on the prevalence and risk factors for gonads impairment, including infertility, following cancer and numerous cancer treatment regimen has significantly increased. However, data remains mostly insufficient for individualized prediction of (future) fertility and pregnancy potential, including the use and success of artificial reproductive technologies (ART). Furthermore, therapies have become increasingly complex as more recent treatment regimen have continuously also implemented novel treatment approaches (e.g. immune therapies such as checkpoint inhibitors) for which no comprehensive data regarding its impact on fertility and pregnancy outcomes is available, yet. It is crucial to carefully balance risk-benefit between fertility preservation (FP) procedures and potential of gonadal function/fertility impairment, to examine the efficiency and safety, as well as to assess patients' satisfaction regarding the FP procedures. Answering these questionsis highly relevant as it has been shown that fertility capacity and post-treatment gonadal function may represent a significant part of quality of life in young cancer survivors. The study therefore aim to set up a large-scale registry of emerging data collection programmes to evaluate the gonadotoxic risks, including the prevalence and course of ovarian dysfunction and/or fertility impairment and premature ovarian insufficiency following specific treatments, identification of further risk factors and predictive markers to enhance precision survivorship research in this field. Additionally, data on the use of fertility preservation/hormonal treatment and patients' satisfaction related to these procedures in Europe will be analysed to support patient-centric care. Reproductive health counselling should not be limited to evaluating the risk of gonadotoxicity and offering fertility preservation to those at risk. It should also include evaluating the impact on post-treatment sexuality, menopausal symptoms management, and the counselling on contraception. In addition to clinical information, whole genome sequence data will be generated for selected study participants with evidence of varying impact of gonadotoxic therapies on reproductive function to find genetic variants associated with risk of reproductive and organ toxicity. The data collection will focus on all different cancer diseases, including diseases which are less common such as different types of sarcomas. This will be a significant development to the current state of information in existing registries. The primary objectives of this prospective analysis of European ongoing adolescent and young adult (AYA) cancer patient cohorts are: 1. To establish a database with relevant clinical characteristics at time of diagnosis, cancer therapy received and post-cancer clinical and reproductive outcomes by following AYA cancer patients longitudinally. 2. To evaluate the effect of cancer therapies on ovarian function and reproductive potential. 3. To evaluate fertility preservation measures performed, their risks and efficacy. 4. To evaluate the impact of fertility preservation measures on the risk of cancer relapse. 5. To evaluate occurrence of pregnancies/live births naturally conceived (including unplanned) or through medical assistance post-cancer and the obstetrical complications and neonatal health following the use of cryopreserved oocytes or gonadal tissue. 6. To set up a genetic database based on whole genome sequencing of AYAs of the cohort. For this objective a Substudy 1 : " Development of risk prediction models based on clinical and genetic data " will be conducted. 7. To develop prediction models for organ toxicities in cancer patients (objective included in Substudy 1). 8. To evaluate the effect of cancer therapies on sexuality and quality of life. For this objective a Substudy 2 : "Sexual Health" will be conducted. 9. To evaluate the use and counselling on contraception. For this objective, a Substudy 3 : "Contraception" will be conducted. 10. To describe management of treatment-induced premature ovarian insufficiency (POI) and menopausal symptoms. For this objective a Substudy 4 "Management of POI and Menopause Symptoms" will be conducted. 11. To explore patient's satisfaction receiving counseling and/or undergoing fertility preservation. For this objective a Substudy 5 on "Satisfaction with Fertility Preservation" will be conducted.
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.

In this pilot study, prospectively acquired clinician-collected and participant-collected vaginal swab specimens will be obtained from up to 1000 individuals with signs and symptoms of vaginitis to develop and validate a bacterial vaginosis diagnostic algorithm and evaluate the performance of the Nanopath assay. The Nanopath assay is an amplification-free molecular test that detects pathogens associated with vaginitis. The performance of the Nanopath assay will be assessed by comparing Nanopath assay results to previously FDA-cleared commercial tests and yeast culture.
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.
NCT06804538
Intrauterine insemination (IUI) is a common therapeutic option to treate infertility. Typically performed 36 hours post-hCG injection to trigger ovulation. However, research suggests delaying IUI to 42 hours post-hCG may improve egg quality and sperm synchronization for fertilization, leading to higher pregnancy rates. A proposed superiority study aims to compare IUI timing at 36 hours versus 42 hours post-hCG injection to evaluate its impact on live birth rates. The primary objective is to assess the effectiveness (live birth rates) of IUI at two different post-hCG timing intervals (42-43 hours vs 36-37 hours).

The experience of infertility can cause significant emotional instability, especially for patients awaiting In Vitro Fertilization (IVF) treatment, generating anxiety, stress, and depressive symptoms. This study is a randomized clinical trial assessing the effectiveness of aromatherapy in improving mental health and quality of life in women undergoing infertility treatment. 120 participants will be randomized into three groups (Intervention, Placebo, and Control). The intervention involves the inhalation of true lavender essential oil (Lavandula angustifolia) for four weeks.
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.

NCT07547423
The goal of this clinical trial is to learn if auricular laser acupuncture can improve sleep quality and alleviate related symptoms in female breast cancer patients aged 18 to 75 with insomnia. The main questions it aims to answer are: 1. Does active auricular laser acupuncture improve sleep quality and reduce the severity of insomnia? 2. Does it help lower levels of cancer-related fatigue, anxiety, and depression? Researchers will compare an active auricular laser acupuncture group to a sham control group (receiving no therapeutic laser energy) to see if active laser acupuncture is effective for symptom relief. Participants will: 1. Receive 10 sessions of laser treatment (active or sham) twice a week for 5 weeks, while wearing protective goggles to ensure blinding. 2. Wear an actigraphy wristband and keep a sleep diary to monitor sleep patterns, and undergo heart rate variability (HRV) measurements at baseline and Week 5 (post-treatment). 3. Complete questionnaires assessing sleep, fatigue, mood, and quality of life at baseline, Week 5 (post-treatment), and Week 10 (follow-up).
