Research objectives: To study the associations between combinations of single-nucleotide polymorphisms and behavioural risk factors with heart rate disorders and adverse outcomes in women with premature ovarian failure Examine the associations between combinations of single nucleotide polymorphisms and behavioural risk factors with stable STIs in women with premature ovarian failure. Examine the associations between combinations of single nucleotide polymorphisms and behavioural risk factors with thrombomolia in women with premature ovarian failure Study the associations between combinations of single nucleotide polymorphisms and behavioural risk factors and adverse cardiovascular outcomes in women with premature ovarian failure.

Primary ovarian insufficiency (POI), also known as premature ovarian failure, is an ovarian defect characterized by the premature (before the age of 40 years) depletion of ovarian follicles. POI affects about 1% of women, reaching 30% in some familial cases. This heterogeneous disorder is characterized by progressive cessation of the ovarian function with temporary or intermittent amenorrhea associated with elevated serum FSH concentration and low AMH dosage. Low serum AMH dosage is able to detect a diminished ovarian pool occurring before the onset of FSH elevation and the ultimate deficiency leading to amenorrhea. POI causes infertility and a poor ovarian response in IVF stimulations, and it has important health consequences for affected patients, including psychological distress, infertility, osteoporosis, autoimmune disorders, ischaemic heart disease. Although the cause of POI remains unknown in about 80% of the cases, several mechanisms have been proposed to explain ovarian dysfunction. Currently, a wide spectrum of causes has been linked to POI, including genetic, autoimmune, infectious, or iatrogenic ones. Genetic causes are highly heterogeneous and might explain at least some of the sporadic idiopathic cases, which comprise 50-90% of cases. Ten to fifteen percent of cases are X-linked abnormalities, mainly Turner Syndrome (45,X) or X structural abnormalities such as X deletions, X inversions, isochromosomes or X-autosome translocations. Also fragile X mental retardation 1 (FMR1) gene permutation (defined as having 55 to 200 CGG repeats in the 5' untranslated region of the gene) is another frequent genetic etiology. Irrespectively, the majority of cases remains idiopathic, and identifying precise causative genes for POI has been challenging.

Background: Medical advances have improved survival rates for many cancers and other illnesses. This means that more people are coping with the long-term effects of these treatments. Some treatments can cause female infertility. Ovarian tissue cryopreservation (OTC) may help. Before undergoing a treatment that may damage their fertility, patients may opt to freeze a sample of ovarian tissue. The tissue contains immature egg cells. When thawed, the tissue can be reimplanted. This procedure can help women become pregnant. Objective: This natural history study will create a databank of ovarian tissue. The NIH will provide OTC as a clinical service. The NIH will also request a portion of the tissue to use for research. Eligibility: Females aged 4 to 35 who opt to have OTC before receiving cancer treatment. Design: Participants will be screened. Their existing medical records will be reviewed. They will be asked if they want to donate a portion of their ovarian tissue for research. No more than 20% of the tissue collected will be taken for research. Some other tissues that would otherwise be discarded will also be kept. Medical data from each participant may also be collected and stored in the database. This data may include results of routine blood tests, imaging tests, and other information. The data will be coded for privacy. Participants will answer a questionnaire. They will be asked about their fertility treatment and general health. The survey takes about 30 minutes. They will repeat the questionnaire once a year for 30 years.

Premature ovarian insufficiency (POI) seriously affects the physical and mental health of women. Nowadays, Chinese herbs have huge appeal and potential in treating POI. We have created a new Chinese herbal combination TJAOA101, whereas its safety and efficacy still need to be validated. Hence, we will perform a population-based, multicenter study to confirm the safety and efficacy of TJAOA101 in therapy of POI. We aim to provide a solid evidence for TCM in therapy of POI.

The aim of this study is to evaluate the evolution of quality of sex life of women with POI after introduction hormone replacement therapy through the FSFI scale

Rationale: Due to accelerated germ cell loss, infertility is a major problem in girls with Turner syndrome (TS). Therefore, cryopreservation of ovarian tissue or oocytes before exhaustion of the ovarian reserve may preserve fertility in patients with TS. However, in the majority of females with TS , the ovarian reserve is exhausted before the age of menarche. Early markers indicating and predicting the ovarian reserve are necessary. During mid-childhood the hypothalamic-pituitary-gonadal (HPG) axis is quiescent and gonadotropins are usually unmeasurable. Nonetheless, this axis is active during infancy. Therefore, gonadotropins are measurable with peak values at 3 months of age and with lower (but still measurable) values at 9 months of age, in a period called the minipuberty. The aim of this study is to find markers of ovarian capacity, during the minipuberty, in order to predict ovarian reserve in the future. Objective: The hormonal range of LH, FSH, AMH, inhibin B, testosterone and estradiol in girls with TS during the minipuberty and the relation of the hormone serum levels with the karyotype. Study design: A prospective, cohort study with a duration of 3 years. Study population: Girls with a pre- or perinatal diagnosis TS who are born in a medical centre in the Netherlands during the duration of the study Main study parameters/endpoints: Serum levels of FSH, LH, AMH, inhibin B, testosterone and estradiol at the age of 3 and 9 months.

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 4-12 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.

This is a cross-sectional study in which the investigators will determine the impact of premature/early menopause on MSNA, BP and baroreflex sensitivity in younger (≤49 yr old) and older (≥50 yr old) women. Specifically, aim one will determine mechanisms driving autonomic dysregulation of BP in premature and early menopausal women and aim two will determine mechanisms driving autonomic dysregulation of BP in older menopausal women. The study design outlined below will permit testing of aim one and aim two.

Cervical cancer is one of the most common cancer in women, making it the fourth largest cause of female cancer mortality worldwide. High-risk HPV types (hrHPV) continuous infection is the main cause of the premalignant and malignant lesions of the cervix. The most effective primary prevention of cervical cancer is administration HPV vaccines. There are three prophylactic HPV vaccines including bivalent HPV (2vHPV)， quadrivalent HPV vaccine (4vHPV)，9-valent HPV vaccine (9vHPV) currently. With the widespread of HPV vaccination， the cases related to abnormal menstrual cycle or menstrual irregularities has gradually increased in the Vaccine Adverse Event Reporting System, also the number of reports and studies were increasing. We designed this study to evaluate the statistical association of HPV vaccine and changes in menstrual cycle or menstrual irregularities、amenorrhea. And detect the signal of premature ovarian insufficiency (POI) and related events of three HPV vaccines, and to provide evidence for the safety of HPV vaccines based on the data mining and signal detection method. The research data was obtained from prospective self- developed questionnaire. Before-after study was applied in this study, investigators collect the menstrual cycle data of subjects by the questionnaire and qualitatively interview were taken. The control group is before vaccination, HPV vaccination is Intervention group.
