It presents with nonspecific but often severe symptoms, including chronic pelvic pain (in 70% of cases) and infertility (in up to 40% of cases), imposing significant physical, psychological, economic, and societal burdens. Despite its widespread occurrence, the exact etiology and pathogenesis of endometriosis remain unclear, and no definitive cure exists. Early diagnosis and management are crucial for improving patient outcomes; however, major diagnostic delays persist. Current imaging techniques such as transvaginal ultrasound (TVUS) examination and magnetic resonance imaging, along with biochemical markers lack sufficient specificity. Consequently, confirmation of diagnosis still requires surgical procedures under general anesthesia, i.e.\n\nlaparoscopy (\"key-hole surgery\") and tissue biopsy. This delay exacerbates the disease burden and healthcare costs, underscoring the urgent need for non-invasive, precise diagnostic strategies. This project proposes a multi-modal approach integrating advanced ultrasound imaging with novel biomarkers identified via comprehensive multi-omics analyses, including proteomics, transcriptomics, and immune profiling, of patient-derived endometrial organoids. It aims to understand the underlying mechanisms of reduced endometrial receptivity of embryos in patients with endometriosis. Additionally, we will explore personalized treatment strategies by utilizing patient-specific organoids for drug screening and evaluation of treatment response.\n\nThis project aims to develop a non-invasive diagnostic strategy by integrating:\n\n1.

The diagnosis is typically made based on high levels of follicle stimulating hormone (FSH) and absent or irregular menstrual periods. It leads to infertility and menopause-like effects (hot flashes and thin bones) due to low estrogen levels. POI can result from various factors such as genetic conditions, autoimmune diseases, or previous medical treatments like chemotherapy.\n\nTreatment of POI usually involves hormone replacement therapy and, if pregnancy is desired, assisted reproductive technologies such as in vitro fertilization (IVF) using an egg donor. However, IVF may not be an option for everyone due to personal, religious, ethical or financial reasons. Recent advances in medicine have identified ovarian tissue transplantation (OTT) as a potential solution. OTT involves transplanting either fresh or frozen ovarian tissue into the pelvic area, where it can begin functioning again. Studies in animals and humans have shown success in restoring hormonal function and even achieving pregnancies in some cases. Initial human trials of ovarian tissue transplants from another individual began with identical twins and have since expanded to include non-identical siblings with compatible tissue matches using immunosuppression. Success rates of OTT have been promising, with multiple live births reported between identical twins. Long-term studies indicate that transplanted tissue can remain functional for up to eight years. Ovarian tissue transplantation offers a promising avenue for women with POI to help restore fertility and hormonal function.
