Changes in the estrogen/testosterone balance at menopause may negatively influence the development of diabetic kidney disease. Furthermore, recent studies suggest that changes in hormone levels during perimenopause may influence disease development. Injection of 4-vinylcyclohexene diepoxide (VCD) in B(6)C(3)F(1) mice induces gradual ovarian failure, preserving both the perimenopausal (peri-ovar...

We present the first reported case of juvenile Systemic Lupus Erythematosus with Klinefelter's syndrome in a 14-year-old Iranian boy who had leg ulcers and arthritis. He had low level of testosterone accompanied with hypergonadotropic hypogonadism. This case emphasizes the importance of two X chromosomes as a risk factor for Systemic Lupus Erythematosus in women and men with Klinefelter's syndr...

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...

Factors comprising the metabolic syndrome occur with increased incidence in postmenopausal women. To investigate the effects of ovarian failure on the progression of the metabolic syndrome, female B(6)C(3)F(1) mice were treated with 4-vinylcyclohexene diepoxide (VCD) and fed a high-fat (HF) diet for 16 wk. VCD destroys preantral follicles, causing early ovarian failure and is a well-characteriz...

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...

We examined the prevalence of anti-nuclear antibodies (ANA) in 32 consecutive patients with premature ovarian failure with and without chromosomal abnormalities. Blood samples were taken for karyotype determination as well as detection of autoantibodies, X-terminal microdeletions and spontaneous follicular growth. The correlation between ANA positivity and the age at onset of amenorrhoea, as we...

Follistatin plays an important role in female physiology by regulating FSH levels through blocking activin actions. Failure to regulate FSH has been implicated as a potential cause of premature ovarian failure. Premature ovarian failure is characterized by amenorrhea, infertility, and elevated gonadotropin levels in women under the age of 40. Because follistatin is essential for postnatal viabi...

BACKGROUND Clinically, premature ovarian failure (POF) is defined as unexplained amenorrhoea (> 6 months) with a high FSH level (> 40 IU) before the age of 40 years. POF is a heterogeneous genetic disease with unknown aetiology. Inhibin and activin regulate the FSH level by their opposing actions and thus have been considered as strong candidate genes in the aetiology of POF. METHODS We have ...

Background: Ovarian cancer is the fifth leading cancer-related cause of death in women worldwide and is often diagnosed at advanced stages. Regarding the low sensitivity and specificity of the currently available diagnostic techniques, in the present study, we aimed to evaluate the accuracy of RMI and ROMA indexes and comparing these two indexes with CA-125 and HE4 parameters for the diagnosis ...

current protocols for cancer treatment could lead to the failure of ovarian function and subsequent infertility in women. therefore, utilizing ways to preserve fertility in these individuals seem to be essential. in this review, the full-text of articles which were accessible and had been published during 1976 to 2009 about different methods of female fertility preservation were collected and s...
