Filter by: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.
The aim of this study was to develop electronic systems (e-systems) for oncofertility support, and to examine the comprehensibility, feasibility, usability, and effects on social support and preparation for decision-making.
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.
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.
Majority of transgender and gender nonconforming people seeking medical care are in pubertal and reproductive age. Cross-sex hormones may compromise fertility especially when preceded by puberty blocking regimen. Our current understanding on reproductive needs of transgender persons is insufficient. The guidelines of Endocrine Society and the World Professional Association for Transgender Health prompt the health professionals to provide information on fertility risk and fertility preservation options before initiating hormonal treatment. Currently, no clear tools are available for healthcare professionals. Among several challenges for clinical care are a low clinical awareness, a lack of suitable psycho-educational instruments addressing fertility values that can be used to facilitate discussion between transgender persons and healthcare providers, a lack of established methods for fertility preservation in prepubertal youth, and a lack of long-term data regarding reproductive function, psychological and societal outcomes in this population. Likewise, current data are sparse regarding the experience of transgender and gender nonconforming people with fertility preservation. Our aim is to describe desires, attitudes and knowledge of transgender and gender nonconforming people regarding fertility preservation wishes and reproductive needs.
This study will help the researchers learn more about factors that affect the decisions about fertility preservation and family building made by young women with breast cancer.
The effects of gender transitioning, particularly the effects of testosterone exposure in transgender men, on the oocyte and embryo development are largely unknown. Based on prior studies suggesting that the extracellular RNAs secreted by the ovarian follicle cells reflect the oocyte and embryo biological state, the investigators propose to use these extracellular RNAs to gain insights into the effects of testosterone exposure in transgender men on their oocyte and embryo without impacting the clinical IVF process.
Rationale: Infertility due is a major concern for girls with Turner syndrome (TS) and their parents. Physicians are often asked about possible options to preserve their fertility. However, despite some experimental case reports, clear evidence for fertility preservation in these girls is lacking and many questions remain. Without evidence on the effectiveness of fertility preservation it cannot routinely be offered to girls with TS. Objective: To investigate the occurrence of live birth in women with TS after ovarian tissue cryopreservation in childhood followed by auto transplantation in adulthood. Study design: A national multicentre exploratory intervention study Study population: Girls diagnosed with Turner Syndrome, aged 2-18 years. Intervention: Ovarian tissue cryopreservation in childhood followed by auto transplantation in adulthood. In order to obtain the ovarian tissue for cryopreservation, all girls must undergo a laparoscopy under general anaesthesia which will be performed in academic/university clinics with paediatric surgery. During the laparoscopic intervention, a unilateral oophorectomy will be performed, thereby leaving the other ovary intact for hormone production, ovulation, spontaneous pregnancies and as an auto transplantation site for cryopreserved-thawed ovarian cortical tissue later on. Furthermore, a small sample of the ovarian cortex will be used to assess the oocyte quality and genetics (e.g. the presence of germ line mosaicism). Oocytes will be karyotyped by using Fluorescence in situ hybridization (FISH). Karyotypic and hormonal data will be collected once at the yearly clinical visit at the paediatric-endocrinologist. Therefore, a buccal swab and one extra blood sample will be taken and evaluated during the routine laboratory evaluation. In the future, auto transplantation of frozen-thawed ovarian cortex strips will be performed.
The PREgnancy and FERtility (PREFER) study is a comprehensive program aiming to optimize care and improve knowledge around the topics of fertility preservation and pregnancy issues in young breast cancer patients. The program was initiated at the National Institute for Cancer Research, IRCCS AOU San Martino - IST in Genova (Liguria Region, Italy) and then it has been spread to other Italian Institutions under the umbrella of the Gruppo Italiano Mammella (GIM) study group. It is composed of two distinctive studies, one assessing fertility (i.e. PREFER-FERTILITY) and the other pregnancy (PREFER-PREGNANCY) issues. Hence, two different study protocols were developed under the umbrella of the PREFER registry. PREFER-FERTILITY aims to obtain and centralize data about the preferences and choices of young cancer patients on the fertility preservation strategies available in Italy. Furthermore, it aims to assess the outcomes of patients undergoing one or more strategies for fertility preservation in terms of success of the techniques (i.e. recovery of ovarian function, number of cryopreserved oocytes, post-treatment pregnancies) and safety (i.e. long-term survival outcomes). PREFER-PREGNANCY has two main objectives: 1) to obtain and centralize data on the management of breast cancer diagnosed during pregnancy, the obstetrical and paediatric care of children born after prior in utero exposure to anticancer treatments, and the long-term survival outcomes of these patients; 2) to obtain and centralize data on the clinical outcomes of breast cancer survivors that achieve a pregnancy after prior diagnosis and treatment of breast cancer.
While most of the children spontaneously recover menstruation or experienced normal puberty after chemotherapy, their ovarian reserve may be impaired by treatment inducing future infertility. Fertility preservation is currently proposed for selected prepubertal patients with a high risk of premature ovarian failure after treatment (mostly conditioning regimen for bone marrow transplantation). For patients with low or moderate risks, counselling is very difficult and no fertility preservation procedure is usually proposed for these patients as no marker of the ovarian reserve has been validated in this young population to assess the individual risk. The primary objective of the study is to prevent long-term treatment-related infertility by detecting the young patients who normally progressed to menarche but have a reduced ovarian reserve. These patients may benefit from particular follow-up and fertility preservation procedure.
