35 Clinical Trials for Various Conditions
The purpose of this study is to offer gonadal tissue freezing and storage to children who are diagnosed with a disorder of sex development (DSD), who are at increased risk of infertility and certain malignancies (cancer). This study involves the storage of gonadal tissue that is being removed for medical reasons (e.g. prevention of cancer development). It includes the processing and freezing of this gonadal tissue, hopefully for potential future use. The tissue will then be stored long-term until the child wishes to try to use the tissue.
The "Gonadal Dysgenesis Tissue Cryopreservation for Fertility Preservation" study is open to a subset of patients with disorders of sex development (DSD) which is associated with the risk of malignancy and a high risk of infertility or sterility. For these patients, experimental gonadal tissue cryopreservation is the only fertility preservation option available. The overall objective of this study is to determine the safety and efficacy of gonadal tissue cryopreservation as a method of preserving fertility and/or restoring hormonal function in patients with gonadal dysgenesis who are at risk of decreased fertility potential or malignancy.
The goal of this observational study is to learn about fertility preservation for pre-pubertal, peri-pubertal, and adult participants that are unable to pursue clinical standard of care fertility preservation such as egg (oocyte) and embryo cryopreservation. In addition, this study will provide research tissue for the following Specific Aims: 1. To optimize techniques for cryopreservation of ovarian tissues from patients at significant risk for infertility. 2. To investigate factors affecting successful maturation ovarian tissue. Participants will undergo a surgical procedure to remove an ovary (oophorectomy) to preserve their gonadal tissue for fertility preservation.
This study will compare efficacy of ovarian tissue freezing using slow-freeze versus vitrification methods.
Background: Turner Syndrome, galactosemia, and premature ovarian insufficiency are all conditions that may make it very hard or impossible for a person to become pregnant and have their own child. Researchers want to learn more about why this happens and if freezing Gonadal tissue allows for fertility preservation. Objective: To find out why people with certain conditions have can have premature ovarian insufficiency (POI or early menopause) and individuals with variations in sex characteristics have trouble getting pregnant and if freezing the gonads tissue from them will help to have their own child in the future. Eligibility: Individuals aged 2-12 who have Turner Syndrome or galactosemia. Also, females aged 13-21 with premature ovarian insufficiency and Individuals with variations in sex characteristics Design: Participants will be screened with a medical history. Participants may have a physical exam and blood tests. Their body measurements may be taken. These include weight, height, arm span, skin fold, and sitting height. They may fill out surveys about their quality of life, body image, and health. Participants may have a transabdominal pelvic ultrasound. A probe will be placed on their belly and will take pictures of the organs in the pelvis. They may have a transvaginal pelvic ultrasound performed while asleep in the operating room if needed. Participants may have surgery to remove an gonads and skin biopsy. The removed tissue will be frozen and stored. The tissue will have to be stored for many years. NIH will pay to store the tissue for 1 year. After that, participants will have to pay for storage. A piece of the gonads (no more than 20%) will be used for research Travel, lodging and meals for participants traveling greater than 50 miles will be reimbursed based off the government rate. Local participants will not be reimbursed. Participants will have a checkup 6 weeks after surgery one or more follow-up visits 6-18 months after surgery. They may have phone follow-up every 12-24 months after surgery. Participation will last 30 years.
Very little is known about how medical providers can help adolescent and young adults (AYAs) and their caregivers make decisions about fertility preservation (sperm banking) before beginning cancer treatment. The purpose of this study is to see if having a guided conversation about fertility preservation increases preservation rates and/or satisfaction with the decision among AYA males with cancer. The primary hypothesis is that compared to standard of care control group (routine fertility consult at diagnosis, n=20), AYAs in the intervention arm (routine fertility consult at diagnosis + FP Decision Tool and Facilitated Conversation by trained interventionist) will have higher rates of FP uptake. The secondary hypothesis is that families in the intervention group will report better FP decision quality compared to those in the control arm.
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.
Latrogenic infertility as a result of cancer treatment has a profound effect on long-term quality of life in survivors of reproductive-age cancers. Oocyte cryopreservation prior to cancer treatment has been associated with improved quality of life, with a potential ability to reduce long-term decision-related regret in cancer survivors. Though letrozole plus gonadotropin and and tamoxifen plus gonadotropin are currently routinely used worldwide in ovarian stimulation cycles for fertility preservation in patients with estrogen-receptor-positive breast cancer, it is not clear which of the two might lead to improved oocyte yield. Improved knowledge about the efficacy of these medications, with regard to oocyte yield, has the potential to significantly improve quality of life in reproductive-age breast cancer survivors.
Testicular tissue cryopreservation is an experimental procedure where a young boy's testicular tissue is retrieved and frozen. This technique is reserved for young male patients who are not yet producing mature sperm, with the ultimate goal that their tissue may be used in the future to restore fertility when experimental techniques emerge from the research pipeline.
The purpose of this research is to obtain ovarian tissue from female participants who will receive therapy which is expected to result in a loss or impairment of ovarian function and/or infertility and wish to preserve (freeze) ovarian tissue for the purpose of initiating a pregnancy in the future. Removal of the ovary for cryopreservation is an investigational procedure. 100% of the tissue will be used for the participant's future use. There have been 86 pregnancies as a result of frozen ovarian tissue that has been re-implanted back into the pelvis and hormonal function has been restored in individuals for up to 7 years. By doing this study, the investigators hope to learn of how to successfully freeze and thaw ovarian tissue in a manner that permits subsequent use by patients at some point in the future. Participation may also advance our knowledge of how to successfully mature follicles and oocytes (eggs) that are contained in these tissues which may help others in the future.
The purpose of this study is assess the effects of oncology treatment on ovarian reserve and also to better understand the experiences, thoughts and feelings of women scheduled to undergo chemotherapy/radiotherapy and seeking fertility preservation at Weill Cornell Medical College (WCMC).
Background: - Some treatments for cancer or other diseases can lead to infertility in women. These treatments include chemotherapy, some stem cell transplants, and pelvic radiotherapy. They are called gonadotoxic therapies. Women can now have their eggs frozen before they have these treatments. This may allow them to get pregnant later. Researchers want to learn more about this technology and processes. Objectives: - To provide egg freezing for women having gonadotoxic therapies at NIH. To learn more about the effects of these therapies. Eligibility: - Women at least 18 years old who are past puberty and before menopause. They must be scheduled to have gonadotoxic therapies. Design: * Participants will be screened with medical history and blood and hormone tests. They will also have a physical exam and transvaginal ultrasound. * Ovary stimulation: participants will have medications injected under the skin. These increase the chance of fertility. This phase will take about 8 20 days. Participants will have blood drawn and transvaginal ultrasound daily or every other day. Some participants will also have blood thinner injected daily. * Egg retrieval: participants will check in to the hospital. Eggs will be removed with a needle during a short surgery. Participants will be awake but sedated. * Participants may stay overnight in the hospital. * They will return every 1 3 days for 1 3 weeks for blood tests. * Mature eggs will be frozen after egg retrieval and immature eggs (which cannot be fertilized for clinical use) will be used for research. Participants can use their eggs in the future at outside, private fertility clinics to try to become pregnant. If the eggs are stored for more than 5 years, participants must pay for storage.
The FIRST project is a national fertility preservation registry for young women facing cancer treatments. The investigators will examine how different cancers and treatments affect the reproductive health of young survivors. This prospective cohort study seeks to recruit young women close to time of cancer diagnosis and treatment. Participants will answer a yearly questionnaire on their current health. A subset of participants will provide dried blood spots to measure reproductive hormones. The primary goal of the study is to determine the risk of infertility and time to pregnancy in young female cancer survivors.
Klinefelter syndrome occurs in 1 in 600 males and is a common cause of infertility in men. It appears scar tissue forms in these boys' testicles, leading to progressive destruction over their lifetimes. Advanced reproductive technology can be used to surgically retrieve sperm from these individuals, but these methods have a 50% failure rate in adult Klinefelter patients. Younger men have higher success rates, suggesting that adolescence and young adulthood may be the best time to extract sperm, but these techniques have not been studied in Klinefelter patients younger than 26 years of age. Additionally, there is currently no way to predict which Klinefelter patients will have success with these methods and which of them will not. This trial will explore sperm extraction in Klinefelter syndrome in an age range (12-25 years) that has never been studied, with the ultimate hope of improving the potential for fertility in these patients. The specific goals of this study are to determine the ideal age for sperm retrieval in Klinefelter patients and to establish factors that can be used to predict which of these patients will have a higher likelihood of success with advanced reproductive technology. The hypothesis is that younger Klinefelter patients will have higher sperm retrieval rates.
To provide a novel fertility preservation option for patients facing a fertility threatening cancer diagnosis or treatment regimen by establishing an ovarian tissue cryopreservation program. To determine if ovarian tissue cryopreservation provides women with a useful, successful option for fertility preservation The hypothesis is that ovarian tissue cryopreservation for fertility preservation provides an alternative option for fertility preservation.
The purpose of this study is to preserve the fertility potential in females diagnosed with cancer by vitrifying (rapidly freezing) their oocytes (eggs) before undergoing treatment for their cancer.
The purpose of this study is to offer an alternative method to women who wish to preserve the possibility of fertility, as well as to learn more about the ability of human eggs to survive and function after long term storage in frozen ovaries (ovarian tissue cryopreservation). The study will seek to preserve ovarian tissue and reproductive potential for patients whose medical or surgical treatment may harm ovaries or remove ovarian tissue.
The specific aim of this study is to further develop methods of oocyte cryopreservation and evaluate their impact on reproductive outcomes.
The purpose of this study is to evaluate the effectiveness of a multi-component intervention to improve young cancer survivors' engagement in goal-concordant oncofertility care, concurrently with observing and gathering information on how the intervention is implemented. The investigators hypothesize that implementation of the intervention will result in increased young cancer survivors' engagement in goal-concordant oncofertility care.
The study hopes to contribute to the development of technologies of ovarian tissue freezing-thawing and in vitro maturation of immature eggs such that a person at risk for premature ovarian failure might be able to conceive a genetically related child.
The "Testicular Tissue Cryopreservation" study is open to a subset of patients facing disease or treatment regimens that could lead to infertility (gonadotoxic therapies). For some of these patients, experimental testicular tissue cryopreservation is the only fertility preservation option available. The overall objective of this study is to determine the feasibility and acceptability of testicular tissue cryopreservation in male patients of all ages who have a condition or will undergo a treatment that can cause infertility.
The goal of this study is to learn about fertility preservation in the gender-diverse community. The main objectives it aims to understand are to: 1. To optimize techniques for cryopreservation of ovarian tissues, including determining efficacy of cryopreservation techniques. 2. To investigate factors affecting ovarian tissue and follicles, such as previous treatment with leuprolide acetate, or hormone therapy
The purpose of this study is to see if the investigators can obtain non-inferior clinical outcomes (similar numbers of oocytes) using the Cardinal protocol, a cost-conscious, low-intensity egg freezing protocol, compared to other routinely used high-intensity clinic protocols. This is a new program for Stanford's Fertility Clinic, so the investigators are assessing patient experience and cost-benefit of a low-cost, low-intensity approach that has demonstrated non-inferiority in IVF for infertility treatment, but has not been similarly evaluated in egg freezing. All enrolled participants will choose the Cardinal protocol or the routine high-intensity protocol designated by their physician. The investigators will then assess number of eggs retrieved, as well as patient satisfaction, cost, and time needed off work to complete the egg freezing cycle. The study's findings could ultimately open the door to implementation of lower-cost standardized protocols that would be more affordable and accessible to people who may otherwise not be able to pursue fertility preservation.
The goal of this study is to learn about fertility preservation in the gender-diverse community. The main objectives it aims to understand are to: 1. Optimize techniques for processing and cryopreserving testicular tissue. 2. Determine presence and number of germ cells (sperm precursors) in the patients' testicular tissue. 3. Develop next generation cell- and tissue-based therapies for preserving fertility and treating infertility.
Women of reproductive age who will receive treatment for cancer that includes chemotherapy may participate in a study measuring ovarian function over time. Eligible women are asked to complete a questionnaire, a menstrual diary, a brief physical examination, an ultrasound, and a blood test before, during and after cancer treatment.
The purpose of this investigation is to offer the opportunity for young women to cryopreserve (freeze) their oocytes (eggs) for use with IVF at a later point in time.
Women of reproductive age who will undergo cancer treatment may participate in a study to surgically remove ovarian tissue and store it, frozen, for their potential use in the future. 20% of collected tissue will be used for research.
The purpose of this study is to compare two different ways to administer Letrozole to determine their effectiveness in blocking estrogen production during ovarian stimulation in patients with breast cancer prior to chemotherapy/radiotherapy so that oocytes or embryos can be cryopreserved and patients can possibly achieve a pregnancy after the treatment of breast cancer. During standard ovulation stimulation, the estrogen levels will exceed normal levels and may reach 10 times the normal level for a 2 week period. This may not be desirable in breast cancer patients. The study hopes to determine if the investigators can stimulate oocyte development in the conventional way and administer different doses of Letrozole as the oocytes develop, to keep estradiol levels low, increase the number of oocytes the investigators are able to recover, and improve the quality of those oocytes.
The purpose of this study is to determine the best way to freeze eggs in order to preserve the fertility potential of young women.
