NCT06211569
Our study aims to assess the prevalence of adenomyosis and endometriosis in patients consulting for elective fertility preservation through the diagnosis of these pathologies by transvaginal pelvic ultrasound. Imaging data will be compared with clinical data (patient characteristics, clinical symptoms) as well as the assessment of anxiety, depression, and quality of life collected from the women.

Cancer treatments, despite their increasing effectiveness, carry a significant risk of gamete toxicity. Women of reproductive age are commonly offered fertility preservation (FP) before starting their treatment. However, few studies have analyzed the long-term reproductive outcomes of these interventions, nor how patients ultimately use or do not use the FP options once in remission. This project aims to better understand the effectiveness, utilization, and psychological impacts of these strategies. This work is part of an effort to understand and evaluate fertility preservation practices implemented for women of reproductive age undergoing cancer treatment at the Amiens-Picardie University Hospital (CHU). Its objective is to document patient pathways, clinical decisions, techniques employed, and reproductive outcomes observed after remission, in order to identify potential areas for improvement in the support and follow-up of these patients, thereby enhancing the overall quality and coordination of care. This work is conducted alongside the development of a fertility observatory at the Department of Medicine and Reproductive Biology, CHU Amiens-Picardie.
NCT07138469
Previously reserved for pathological cases, oocyte cryopreservation for non-medical reason also named elective fertility preservation (EFP) is now authorized in France for women aged 29 to 37 following the revision of the bioethics law on August 2nd 2021. Currently, French data related to this new practice are lacking. The aim of this study is to conduct a preliminary assessment 3 years after approval of elective oocyte cryopreservation in France, evaluating the knowledge and perspectives of women undergoing elective fertility preservation in order to gain a better understanding of this new population and define the socio-economic and demographic profiles to improve care quality.
NCT07077876
This observational study aims to evaluate the obstetric and oncological outcomes of patients diagnosed with endometrial adenocarcinoma (EAC) or atypical endometrial hyperplasia (AEH) who underwent conservative treatment at the CLASS Hysteroscopy Center of Fondazione Policlinico Universitario A. Gemelli IRCCS in Rome. Eligible patients include women who received hysteroscopic surgery and hormonal therapy either to preserve fertility or due to medical contraindications to standard radical surgery. Follow-up lasts 12 months.
NCT05372549
Whether it is for oncology or personal reasons, fertility preservation allows participants to preserve their oocytes (eggs) at their current age and condition for a better chance of having a baby in the future. In order to proceed with fertility preservation, participants will need to undergo in vitro fertilization (IVF), which is standard practice, and take stimulation medication to stimulate production of more follicles. The combination of both Rekovelle and Menopur for fertility preservation may increase ovarian response to stimulation and increase the number of oocytes retrieved to give better chances of embryos once the oocytes will be fertilized. The goal in this study is to understand the effect of oxydative stress on the quality of oocytes. For the purpose of the study and to evaluate this connection, serum levels of oxidative stress and cf-DNA in your blood will be measured. Oocyte quality will also be assessed with Magenta, a prediction tool utilizing artificial intelligence (AI). This method is non-invasive and has no risks on the oocytes.
NCT06289062
This multicenter, prospective clinical trial is designed to enroll PD-L1 expression-positive patients with stage IB1 cervical cancer who desire fertility preservation to undergo neoadjuvant chemotherapy in combination with a PD-1 inhibitor to evaluate the rate of complete pathologic remission, treatment-related adverse events, pregnancy rate, miscarriage rate, preterm birth rate, live birth rate, EFS and OS.
NCT06227949
Fertility preservation has been performed before the initiation of cancer therapy as cancer therapy is known to be toxic for ovarian function. However, recent studies have shown that ovarian function is reduced in cancer patients even before they start cancer therapy. Reduced ovarian function has been shown by these patients having fewer mature oocytes (female eggs) and lower peak levels of estradiol (a type of estrogen hormone important for fertility). Other studies have shown that in some types of cancers, cancer patients have lower levels of anti-Müllerian hormone, which is a hormone measured to assess how many eggs patient has remaining in the body. Because of these poorer fertility markers shown in cancer patients prior to therapy, some doctors and researchers believe that alternative medications for stimulating ovaries may prove to be beneficial for stimulating the ovaries during fertility preservation. Currently, luteinizing hormone injections are approved by Health Canada for patients with hypothalamic dysfunction. Hypothalamic dysfunction is a condition whereby lower levels of fertility hormones are produced because of brain dysfunction. Other reasons luteinizing hormone is used in clinical practice is in patients with poor ovarian reserve and patients who are older. Recent research studies have suggested that some oncology patients may be poor responders prior to cancer therapy because of their underlying disease. The exact reasons for this poor response are not known. However, some researchers believe it may be related to the interactions between the brain and fertility organs, similar to patients with hypothalamic dysfunction. Because of this possible similarity to patients with hypothalamic dysfunction, adding luteinizing hormone to follicle-stimulating hormone (the hormone typically used for ovarian stimulation) may be beneficial for fertility preservation. Studies have also shown improved fertility outcomes with the addition of luteinizing hormone in non-cancer patients who were previously known to be poor responders to ovarian stimulation. The clinical trial team is aiming to conduct a randomized controlled trial to evaluate the safety and efficacy of luteinizing hormone in non-hormone sensitive cancer patients (patients with cancer other than the breast, ovary or uterus).
NCT06157619
It has been reported that the potential of In Vitro matured oocytes might be affected by the vitrification process. In fact, the freezing and thawing procedures routinely used in IVF laboratories, have not yet been adapted to oocytes coming from early antral follicles (normally used for In Vitro Maturation). This study aims to compare 2 existing protocols for the Vitrification of In Vitro matured oocytes.
NCT05434936
This study will compare efficacy of ovarian tissue freezing using slow-freeze versus vitrification methods.
NCT04904263
The Advisory Board on Cancer, Infertility and Pregnancy provides a platform where physicians from all over the world can request recommendations regarding the medical care of pregnant women diagnosed with cancer or regarding fertility preservation. The platform will contain different national advisory boards, with their own coordinator and members, as well as an overarching international advisory board with an international coordinator and members from different national boards. To investigate the impact of this platform, a year after its launch, data regarding the incoming requests will be extracted from the website, as well as all recommendation letters.
NCT03954197
Oocyte vitrification after in vitro maturation (IVM) is one of the main techniques for preserving female fertility before chemotherapy for breast cancer. In this technique, originally developed for patients with ovarian pathology, polycystic ovarian syndrome, induction of an LH peak has been shown to improve outcomes. Young women with breast cancer, who are candidates for urgent fertility preservation, do not have ovarian pathology. The objective of the present study is to assess whether the absence of therapeutic intervention prior to oocyte retrieval for IVM in these patients is at least as effective as the injection of hCG or GnRH agonist used in routine practice.
NCT00380406
The purpose of this study is to determine whether gonadotropin releasing hormone agonists (medical therapy) will protect against ovarian failure in reproductive aged women undergoing sterilizing chemotherapy.
NCT02400970
For prepubertal patients, cryopreservation of testicular tissue is the only option available to preserve their fertility before cancer treatment. But testicular autograft raises the issue of the risk of reintroduction of potentially malignant cells. The aim of our study is to develop a specific and sensitive method for residual disease detection in the testicular tissue from patients treated for a solid tumor during infancy, whose fertility may have been compromised by treatments and who benefited of testicular tissue cryopreservation.
NCT00827476
we will perform xenotransplantation and in vitro culture of ovarian tissue from patients undergoing ovarian cortex cryopreservation.
