BACKGROUND: Mammalian folliculogenesis, maturation of the ovarian follicles, require both growth factors derived from oocyte and surrounding cells, including stromal cells. However, the mechanism by which stromal cells and derived factors regulate oocyte development remains unclear. RESULTS: We observed that SENP1, a small ubiquitin-related modifier (SUMO)-specific isopeptidase, was expressed in sm22α-positive stromal cells of mouse ovary. The sm22α-positive stromal cells tightly associated with follicle maturation...

Constant progress in the diagnosis and treatment of cancer disease has increased the number and prognosis of cancer survivors. However, the toxic effects of chemotherapy and radiotherapy on ovarian function have resulted in premature ovarian failure. Patients are, therefore, still expecting methods to be developed to preserve their fertility successfully. Several potential options are available to preserve fertility in patients who face premature ovarian failure, including immature or mature oocyte and embryo cryopreservation...

BACKGROUND: Many reports have shown that various kinds of stem cells have the ability to recover premature ovarian aging (POA) function. Transplantation of human amniotic epithelial cells (hAECs) improves ovarian function damaged by chemotherapy in a mice model. Understanding of how to evaluate the distinct effects of adult stem cells in curing POA and how to choose stem cells in clinical application is lacking. METHODS: To build a different degrees of POA model, mice were administered different doses of cyclophosphamide: light dose (70 mg/kg, 2 weeks), medium dose (70 mg/kg, 1 week; 120 mg/kg, 1 week), and high dose (120 mg/kg, 2 weeks)...

BACKGROUND: Premenopausal women undergoing chemotherapy are at high risk for premature ovarian failure and its long-term consequences. Data on potential markers to evaluate ovarian reserve pre- and posttreatment are limited. Anti-Müllerian hormone (AMH) known for ovarian reserve in reproductive medicine could be a surrogate marker and was assessed in premenopausal breast cancer patients of the SUCCESS A study (EUDRA-CT no. 2005-000490-21). METHODS: We identified 170 premenopausal patients, age ≤ 40 years at trial entry, who received FEC-Doc as taxane-anthracylince based chemotherapy...

Anti-Müllerian hormone (AMH) in women is secreted by granulosa cells in late preantral and small antral follicles. AMH seems to be a very stable marker having some advantages over other biochemical and biophysical markers and is very useful in the assessment of ovarian reserve. AMH measurement may be used in cases of premature ovarian failure, including iatrogenic, due to treatment for cancer, hypogonadotropic hypogonadism, and lastly, in polycystic ovary syndrome (PCOS). It is also a very specific marker of ovarian tumors - folliculomas...

Forkhead box L2 (FOXL2) is a transcription factor, which is involved in blepharophimosis, ptosis, and epicanthus in versus syndrome (BPES), premature ovarian failure (POF), as well as almost all stages of ovarian development and function. FOXL2 has various target genes, which are implicated in numerous processes, including sex determination, cell cycle regulation and apoptosis and stress response regulation in mammals. However, studies regarding the upstream regulation of FOXL2 are limited. In the present study, the promoter of FOXL2 was successfully cloned and registered in Gen Bank, and a dual luciferase reporter (DLR) analysis demonstrated that the luciferase activity was significantly induced by the promoter of FOXL2...

Premature ovarian failure during chemotherapy is a serious problem for young women with cancer. To preserve the fertility of these patients, approaches to prevent chemotherapy-induced ovarian failure are needed. In a previous study, we reported that melatonin treatment prevents the depletion of the dormant follicle pool via repression of the simultaneous activation of dormant primordial follicles by cisplatin. However, melatonin's protective effect was only partial and thus insufficient. In this study, we found that the hormone ghrelin enhances the protective effect of melatonin against cisplatin-induced ovarian failure in mouse model...

OBJECTIVE: Premature ovarian failure associated with Turner syndrome presents clinicians with a vast range of health concerns, including infertility, cardiovascular disease, and decreased bone mineral density, in addition to psychological sequelae. Hormone therapy is paramount in managing these complications, but the additional needs in the postpartum period for those who are able to carry out a successful pregnancy have not been described. METHODS: We present a case of severe postpartum depression (PPD) with psychotic features in a patient with Turner syndrome, which presented at 4 weeks after the birth of her first child via egg donation RESULTS:: We describe the case of a previously well 32-year-old patient with an 46 X, i(Xq) karyotype, who went through a 4-week intensive inpatient treatment course for PPD, requiring electroconvulsant therapy for persistent infanticidal and suicidal ideation...

A 31-year-old lady, diagnosed to have premature ovarian failure in the gynecology clinic, was referred for endocrine assessment because of an abnormal thyroid function test. Clinical examination revealed hypotension, and fungal skin infection under her atrophic breasts. Thyroid stimulating hormone (TSH) level was very high. Assessment of the suprarenal function revealed evidence of Addison's disease. Polyglandular autoimmune dysfunction was diagnosed. She was treated with prednisone, fludrocortisone, and levothyroxine with significant improvement of her general condition and blood pressure...

Premature ovarian failure is one of the side effects of chemotherapy in pre-menopausal cancer patients. Preservation of fertility has become increasingly important in improving the quality of life of completely recovered cancer patients. Among the possible strategies for preserving fertility such as ovarian tissue cryopreservation, co-treatment with a pharmacological adjuvant is highly effective and poses less of a burden on the human body. Melatonin is generally produced in various tissues and acts as a universally acting antioxidant in cells...

This review discusses the current state of our understanding regarding the genetic basis of the most important reproductive disorders in women. For clarity, these disorders have been divided into eugonadal and hypogonadal types. Hypogonadal disorders have been further subdivided according to serum gonadotropin levels. Our review focuses on historical and recent data regarding the genetics of the hypothalamic-pituitary-gonadal axis dysfunction, as well as the development and etiology of eugonadal disorders including leiomyomata, endometriosis, spontaneous ovarian hyperstimulation syndrome, polycystic ovarian syndrome, mullerian aplasia, and steroid hormone resistance syndromes...

It has been shown previously that homozygous and compound-heterozygous variants affecting protein function in the human NLRP genes impact reproduction and/or fetal imprinting patterns. These variants represent so-called 'maternal effect mutations', that is, although female variant carriers are healthy, they are at risk of reproductive failure, and their offspring may develop aberrant methylation and imprinting disorders. In contrast, the relevance to reproductive failure of maternal heterozygous NLRP7 variants remains unclear...

Although age-related ovarian failure in female mammals cannot be reversed, recent strategies have focused on improving reproductive capacity with age, and rapamycin is one such intervention that has shown a potential for preserving the ovarian follicle pool and preventing premature ovarian failure. However, the application is limited because of its detrimental effects on follicular development and ovulation during long-term treatment. Herein, we shortened the rapamycin administration to 2 weeks and applied the protocol to both young (8 weeks) and middle-aged (8 months) mouse models...

It has long been believed that most female mammalian species lose the ability to generate oocytes in postnatal ovaries. Recent evidence has demonstrated the isolation and culture of female germline stem cells (FGSCs) from adult mice and humans. However, the process and mechanisms of FGSC differentiation in vivo following transplantation have not yet been studied. Here, we isolated and characterized FGSCs from a single EGFP-transgenic mouse, and traced the development and behavior of transplanted FGSCs (F-TFs) in vivo...
