OBJECTIVES: Primary ovarian failure is a rare disorder, and approximately 90% of cases are of unknown etiology. The aim of this study was to search for mutations in NANOS3, a gene that was recently related to the etiology of primary ovarian failure, in a group of Brazilian women. METHODS: We screened for NANOS3 DNA variants in 30 consecutive women who were previously diagnosed with primary ov...

INTRODUCTION A case of premature ovarian failure with concomitant findings of Robertsonian translocation between 15 and 21 chromosomes is reported here. The aforementioned karyotypic aberration has not been reported in the context of premature ovarian failure to date. CASE PRESENTATION We present a case of premature ovarian failure in a 27-year-old infertile Kurdish Iranian woman with a Rober...

Background: Ovarian cysts are among the diseases which cause reproductive failure and economic losses in dairy herds. High yelding dairy cattles are suseptable to reproductive failure caused by ovarian cysts, as a result of their exposure to stressful coditions during lactation. OBJECTIVES: This study aimed to monitor metabolic profile tests in dairy cows with ovarian cysts in comparison with c...

BACKGROUND: Ovarian antibodies as detected by indirect immunofluorescence have been used to detect ovarian autoimmunity, but to our knowledge the rate of false positive findings using this method has never been reported. METHODS: Here we examine whether a commercially available ovarian antibody test system, using cynomologous monkey ovary, might be useful in the diagnosis of autoimmune prematur...

The ovarian reserve represents the stock of quiescent primordial follicles in the ovary which is gradually depleted during a woman's reproductive lifespan, resulting in menopause. Müllerian inhibiting substance (MIS) (or anti-Müllerian hormone/AMH), which is produced by granulosa cells of growing follicles, has been proposed as a negative regulator of primordial follicle activation. Here we sho...

Ovarian dysfunction before the age of 40 years, characterized by hypergonadotropic hypogonadism and presenting with either primary or secondary amenorrhea, is called primary ovarian insufficiency (POI). POI has a significant genetic component, but the specific genetic cause is often unknown. A novel candidate gene for POI, PSMC3IP, has recently been identified. The aim of this study was to inve...

BACKGROUND There is a lack of evidence regarding current screening practices for incipient ovarian failure in young women following gonadotoxic therapy and the most appropriate form of estrogen replacement. This study examined the (i) prevalence and management of ovarian failure and (ii) quality-of-life implications of early menopause (EM). METHODS A medical case note audit for 288 women with...

OBJECTIVE To prospectively estimate the risk for earlier ovarian failure among women undergoing hysterectomy with ovarian preservation, as compared with women of similar age without hysterectomy. METHODS A prospective cohort study was conducted among women aged 30 to 47 years undergoing hysterectomy without bilateral oophorectomy (n=406) and women with intact uteri (n=465). Blood samples and ...
