We explored the therapeutic effects of low-intensity pulsed ultrasound (LIPUS) on a rat model ovarian damage induced by cyclophosphamide. A total 44 female rats with premature insufficiency cyclophosphamide were randomly divided into two groups (an group and control group); 22 normal without also included as third group. The was treated LIPUS, while other received same treatment but any power o...
Premature Ovarian Failure (POF) is cessation of ovarian functions before the age of 40 years with consequent cessation of menstruation. The objective of study was therefore to evaluate the emotional reaction and self-efficacy of women with POF. Forty-two women confirmed to have Premature Ovarian Failure seen at the outpatient clinic of Maternity Hospital fulfilled the study criteria, were enrol...
BACKGROUND To evaluate the involvement of immune abnormality in patients with idiopathic premature ovarian insufficiency (POI). In addition to the known etiology, autoimmune disorders may be a pathologic mechanism for POI. MATERIALS AND METHODS Our study was a prospective controlled trial. Twenty women with POI, reasons other than autoimmune excluded, were enrolled in this study. The control ...
STUDY QUESTION What is the optimal management of women with premature ovarian insufficiency (POI) based on the best available evidence in the literature? SUMMARY ANSWER The guideline development group (GDG) formulated 99 recommendations answering 31 key questions on the diagnosis and treatment of women with POI. WHAT IS KNOWN ALREADY NA. STUDY DESIGN, SIZE, DURATION This guideline was pro...
PURPOSE Premature ovarian insufficiency (POI) is defined as the cessation of the ovarian function before the age of 40 years. POI aetiology may be related to iatrogenic or endogenous factors and in many cases remains unclear. The aim of this review was to characterize the long-term consequences of POI. METHODS The available literature regarding the long-term consequences of POI from MEDLINE h...
BACKGROUND Tetrasomy X is a rare chromosomal aneuploidy seen in girls, associated with facial dysmorphism, premature ovarian insufficiency and intellectual disability. A Rathke's cleft cyst (RCC) is a remnant of Rathke's pouch which may cause multiple pituitary hormone deficiencies by exerting pressure on the pituitary gland in the sella. METHODS/RESULTS The patient was diagnosed with tetraso...
BACKGROUND The fragile X premutation is characterized by a large CGG repeat track (55-199 repeats) in the 5' UTR of the FMR1 gene. This X-linked mutation leads to an increased risk for premature ovarian failure; interestingly, the association of repeat size with risk is non-linear. We hypothesize that the premutation-associated ovarian insufficiency is due to a diminished oocyte pool and examin...
Primary ovarian insufficiency (POI) is a critical fertility defect characterized by an anticipated and silent impairment of the follicular reserve, but its pathogenesis is largely unexplained. The frequent maternal inheritance of POI together with a remarkable dependence of ovarian folliculogenesis upon mitochondrial biogenesis and bioenergetics suggested the possible involvement of a generaliz...
