Filter by:Autoimmune diseases cause a decreased endometrial receptivity during the implantation window, most likely changing the endometrial cytokines pattern due to dysregulation of the inflammatory processes.Therefore, endometrial cytokine profiles will be compared in women with autoimmune disease and normal, fertile women. The collected endometrial tissue and blood samples will be examined for the cytokines profiling using commercially available ELISA kits. The sample size was calculated choosing, as primary outcome, changes in endometrial LIF concentration between the disease and control Group, which is our main goal. Given a type I error of 5%, a maximum of 21 women are needed for each Group to reach the desired power of 80% to detect the least changes in concentrations.
The reference technique for the conservation of gametes is storage in liquid nitrogen but new vats of nitrogen vapor (storage over liquid nitrogen) or in dry phase (storage in an insulated compartment of liquid nitrogen in a tank Liquid nitrogen) also allow the storage of flakes. The purpose of this work is to evaluate the dry-phase cryopreservation technique of liquid nitrogen compared with liquid-phase storage, depending on the duration of cryopreservation.
During the last decades, there was an improvement of the cancer treatments of the woman and the teenagers. Therefore higher survival rate is described. However, cancer treatments can alter the reproduction functions and reduce considerably the window of the fertility to the adulthood. Therefore, it is recommended to proceed to a fertility preservation by oocytes vitrification when it is possible. The vitrification is a freezing technique allowing high survival rate and similar results by assisted reproductive technologies compared with the use of fresh oocytes. An innovative method of automated vitrification was recently developed. The usual protocol consist to vitrify mature oocytes. However, this strategy cannot be used for hormone -sensitive cancer or when ovarian stimulation is not possible. In these situations, immature oocytes can be collected. It is also necessary to realize an in vitro maturation step for a use by assisted reproductive technology. According to the recent data of the literature, it remains unclear whether the vitrification of ovocytes must be performed before or after in vitro maturation (IVM). Therefore the aim of this study is to study the impact on structure and functions of ovocytes when vitrification is performed before or after IVM. The vitrification will be performed by a semi-automatic method which is an innovative method.
The purpose of this study is to investigate the effect of Fertility-sparing Therapy of Early Endometrial Cancer.
In terms of immunity, pregnancy can be considered a semi-allogeneic transplant. There are several immunological mechanisms for implantation and maintenance of pregnancy by induction of tolerance without induction of immunosuppression. This study wants to evaluate the impact of immunodepression on women's fertility by studying the fertility of transplanted cardiac, renal, hepatic and pulmonary women.
looking at aneuploidy rates in embryos from patients who are going to or have undergone treatment for a malignancy with gonadotoxic treatment.
Concerns with sexual health and fertility are common among cancer patients, survivors and their partners. Literature reviews suggest that over 60% of survivors have reproductive health problems yet fewer than 20% get professional help. This study will test the uptake, use and effectiveness of online, interactive self-help programs for men and women with cancer. Participants in the study will receive up to 6 months of access to the self-help programs without charge. Navigation through the programs can be personalized by setting goals and following links to the most relevant information. The programs cover all cancer sites and common treatments, explaining sexual and fertility side effects. Programs also include step-by-step cognitive behavioral self-help exercises, guidance on available medical treatment options, decision aids, and video stories with actual survivors as well as vignettes with actors. Information for same-sex couples is included. Programs include suggestions on how partners can work together to cope with sexual or fertility issues. The primary hypothesis is that participants will report improvements in sexual function and satisfaction from baseline to 3-month follow-up. Secondary hypotheses will investigate whether more extensive use of the program is associated with better outcomes (dose-response effect) and whether the intervention also improves secondary outcomes such as anxiety, depression, relationship satisfaction, and seeking medical help. Analyses from the data will investigate how many people who are informed of the study decide to participate (uptake), as well as how often participants visit the program and which parts are used most. Both the male and female programs have previously been shown to help cancer survivors and partners in published clinical trials. Participants will be encouraged to invite a sexual partner to join the study, but that will be optional. Partners will be able to be linked for statistical analysis through their unique study identification numbers. Participants' use of the websites will be electronically tracked and compared with questionnaire outcome measures. Outcome measures include online, self-report questionnaires completed at baseline and 3-month follow-up. At 6-month follow-up, participants will complete 2 online ratings of the helpfulness of the programs. Privacy and security are carefully protected. The entire website meets standards for HIPAA (Health Insurance Portability and Accountability Act). Questionnaires are identified with study numbers rather than names or email addresses. Once the study data are analyzed, the list linking participant identifying information (names, email) and study numbers will be destroyed. Any publications resulting from the study will discuss group data and will not contain any information that could be used to identify an individual participant.
Research results suggest changes of physiological parameters such as heart rate, respiration, skin conductance response, sleep duration, sleep quality and skin perfusion during the menstrual cycle. Latest fitness trackers allow to conveniently and non-invasively record these parameters. The present study aims to evaluate whether there is a correlation between physiological parameters and the menstrual cycle i.e. ovulation as measured by a urine ovulation test and the onset of menses. To collect data women will wear two smartwatches and a smartshirt at night. All three devices are CE-approved for sports and fitness.
Analyze the effect of preincubation time of oocyte on the results of ICSI in a oocyte donation model.
The purpose of this study is to help us determine how hormones impact the production of cervical mucus which is a fluid secreted by the opening of the uterus, also called the cervix. During a normal menstrual cycle, cervical mucus changes in response to two hormones that the ovaries make: estrogen and progesterone. Many of the birth control methods women use thicken mucus and make it less likely for sperm to enter the uterus. The goal of this study is to better understand the effects estrogen and progesterone have on the cervical mucus in the body. To do this, the investigators will be using a drug that suppresses natural hormone production for 3 months. Estrogen and progesterone will be artificially replaced to better understand their effects. The investigators will also be studying the effect of a common birth control pill that may work by thickening cervical mucus. Last, the investigators will study some of the cells in the cervix that produce mucus.
