Psychological stress has become a common and important cause of premature ovarian failure (POF). Therefore, it is very important to explore the mechanisms of POF resulting from psychological stress. Sixty SD rats were randomly divided into control and model groups. Biomolecules associated with POF (β-EP, IL-1, NOS, NO, GnRH, CRH, FSH, LH, E2, P, ACTH, and CORT) were measured in the control and ...

Premature ovarian failure (POF) is one of the most common causes of infertility in women. In our present study, we established cyclophosphamide- (CTX-) induced POF rat model and elucidated its effect on ovarian function. We detected the serum estrogen, follicle stimulating hormone, and anti-Müllerian hormone of mice models by ELISA and evaluated their folliculogenesis by histopathology examinat...

STUDY QUESTION Can spontaneous premature ovarian failure (POF) patients derived from population-based biobanks reveal the association between copy number variations (CNVs) and POF? SUMMARY ANSWER CNVs can hamper the functional capacity of ovaries by disrupting key genes and pathways essential for proper ovarian function. WHAT IS KNOWN ALREADY POF is defined as the cessation of ovarian funct...

Premature ovarian failure (POF) is a common condition affecting 1% of women worldwide. There is strong evidence for genetic involvement in POF as many cases are familial, and mutations in several genes have been associated with POF. We investigated variation in FOXE1 polyalanine tract length, following the observation that polyalanine tract deletions are seen in the closely related FOXL2 in pat...

OBJECTIVES Stem cell transplantation has been reported to rescue ovarian function in a preclinical mouse model of chemotherapy-induced premature ovarian failure (POF); however, maintaining the survival and self-renewal of transplanted seed cells in ovarian tissues over the long-term remains a troublesome issue. In this study we aimed to determine whether the CD44+/CD105+ human amniotic fluid ce...

Background: Premature ovarian failure (POF) is a disorder of multi causal etiology. Autoimmunity has been proposed as a mechanism for some cases of ovarian follicle dysfunction which is evident in POF. The aim of this study was to identify the level of auto-antibodies in POF and familial POF patients. Materials and Methods: In this study, auto-antibodies including anti-ovarian antibody (AOA), a...

OBJECTIVE To evaluate associations of premature ovarian failure (POF) with mortality and morbidity in Asian populations. METHODS We identified 1,003 cases of POF among 36,402 postmenopausal women who participated in the Shanghai Women's Health Study, a population-based cohort study. Cox regression and logistic regression models were applied in data analysis. RESULTS After adjustment for pot...

Premature ovarian failure (POF) is a heterogeneous disorder whose aetiology is still unknown. Recently, the autosomal FOXL2 gene, highly expressed in the adult ovary, has been correlated with the disorder. FOXL2 mutations, causing a truncation of the FOXL2 protein in the forkhead domain or in the poly-Ala tract lead to blepharophimosis-ptosis-epicanthus-inversus syndrome associated with POF (BP...

The Premature Ovarian Failure (POF) syndrome is a very heterogeneous clinical disorder due probably to the complex genetic networks controlling human folliculogenesis. Clinical subgroups of POF patients whose aetiology of ovarian failure is based on the same genetic factors are therefore difficult to establish. Some experimental evidence suggests that these genes might be clustered on the femal...

This review presents the genetic disorders associated with premature ovarian failure (POF), obtained by Medline, the Cochrane Library and hand searches of pertinent references of English literature on POF and genetic determinants cited between the year 1966 and February 2002. X monosomy or X deletions and translocations are known to be responsible for POF. Turner's syndrome, as a phenotype asso...
