View clinical trials related to Ovarian Failure.
Filter by:This case-control multicentre trial was performed from January 1, 2017, to May 31, 2018, in University of Health Sciences Bakirkoy Dr. Sadi Konuk Training and Research Hospital and Hitit University Hospital. Adolescents who were in compliance with the inclusion criteria were called by telephone for blood collection and ultrasound on the 3rd day of menstruation after approval from local ethical registration. On days 2-5 of the menstrual cycle, level of follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), prolactin (PRL), and AMH were measured from venous blood samples in both groups. Antral Follicle Counts (AFCs) and ovarian volumes were determined on the same day.
SEGOVA procedure includes - Stem cell therapy, G - Growth factor Platelet Plasma Rich therapy and in Vitro Activation of the ovaries.
The human ovary is the target of an autoimmune attack, usually in organ or non-specific autoimmune disorders. Serum anti-Müllerian hormone (AMH) levels decrease early in menopause and menopause is seen in women with type 1 diabetes mellitus (DM1) at a young age. DM1 is aimed to show DM1 relationship with ovarian reserve based on the assumption that it will have lower AMH levels than controls, secondary to bad glycemic control and autoimmune attack in women.
The purpose of this study is to obtain ovarian tissue from female patients undergoing gonadotoxic treatments or gonadal ablating surgery, and that in consequence may see their future fertility impaired. Participants will be offered to preserve (freeze) and use ovarian tissue for the purpose of conceiving in the future. Although, 86 live births have been reported with ovarian tissue cryo-preservation and grafting, the procedure is still considered experimental. This research, will help us to learn and validate how to perform ovarian tissue cryo-preservation and thawing in the fertility preservation context.
The use of adjuvant chemotherapy in younger women with early breast cancer (EBC) has substantially improved the long-term outcome. However, this benefit is associated with long-term toxic effects which are becoming more important as prognosis improves. These include premature menopause and infertility in young pre-menopausal women. The incidence of premature menopause depends on the type and intensity of chemotherapy and the patient's age. In women <35 years old, the long-term (3 years after diagnosis) incidence of amenorrhea is similar to women who have not received chemotherapy, at ∼ 10%, but this increases to 50% in women between 35 and 40 years old, and can be up to 85% in women >40 years. Premature ovarian failure has major consequences including sexual dysfunction and infertility, and the latter may be of great concern to younger patients with breast cancer and has a bearing in influencing treatment decisions in almost 30% of cases. Currently, there is no standard treatment for preventing chemotherapy-induced ovarian failure. Previous studies have suggested that temporary ovarian suppression with a gonadotropin-releasing hormone (GnRH) analogue may preserve ovarian function both in humans and animal models. Clinical data are conflicting. For example, a recent Italian multi-center phase III study Prevention of Menopause-Induced by Chemotherapy: A Study in Early Breast Cancer Patients-Gruppo Italiano Mamella 6 (PROMISE-GIM6) reported that the use of GnRH analogue, triptorelin during chemotherapy in pre-menopausal patients with EBC, reduced the occurrence of chemotherapy-induced early menopause with four pregnancies after a 26-month follow-up [one in the chemotherapy alone arm and three in the triptorelin with chemotherapy arm]. In contrast, another trial suggested that the use of goserelin concurrently with neoadjuvant chemotherapy did not significantly reduce incidence of amenorrhea 6 months after the end of chemotherapy compared with those receiving chemotherapy alone and only two pregnancies were recorded [one in each arm] with a follow-up of 2 years.
The developement of a new, stable measurement of the Antimuellerian Hormon (AMH) together with Roche Diagnostics International (Rotkreuz, CH) shall enable an automized and timely measurement of AMH values in blood samples.
This prospective nonrandomized multicenter phase I study, will evaluate the feasibility of performing uterine transposition before chemoradiation for rectal cancer and uterine reimplantation after the treatment.
The purpose of this study is to determine whether the pelvic wall or the ovary represents a better location for the maturation of follicles in the context of ovarian transplantation after cryopreservation of ovarian tissue before cytotoxic therapies.
To gain insight by means of a discrete choice experiment questionnaire into characteristics of medically assisted reproduction (MAR) with artificial gametes (AGs) valued by couples confronted with ovarian failure and their physicians and the trade-offs they make between these treatment characteristics.
More than two million American women are breast cancer survivors. Approximately one-third of these women are premenopausal at diagnosis and face issues related to reproduction as they undergo cancer treatment. Ovarian function after breast cancer diagnosis has implications on breast cancer prognosis, choice of adjuvant therapy and reproductive issues such as desire for fertility or concerns about menopause. Therefore, tools to accurately predict ovarian function in breast cancer survivors could significantly impact physicians and patients in counseling, medical and surgical treatment choices, and consideration of fertility preservation options. The goal of this proposal is to identify pre-chemotherapy hormonal, genetic and ovarian imaging markers that can predict ovarian failure and characterize the course of ovarian function after chemotherapy. The investigators plan to follow a group of young women from breast cancer diagnosis to five years after chemotherapy. The investigators will study the following risk factors: blood hormone levels that reflect ovarian function, genetic mutations that affect how individuals metabolize chemotherapy, and ovarian size and egg count by MRI and ultrasound. The investigators hypothesize that these biomarkers are related to risk of ovarian insufficiency singly. After examining these individual risk factors for ovarian failure, the investigators will put them together into an Ovarian Failure Clinical Predictive Index. This index will be a tool similar to the Gail Model that can be used to determine individual risk for ovarian failure. This tool would assist young breast cancer patients and their physicians in making treatment decisions that would impact cancer survival and reproduction.
