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...

BACKGROUND Premature ovarian failure (POF) is an ovarian defect characterized by the premature depletion of ovarian follicles before the age of 40, representing one major cause of female infertility. Mutations in bone morphogenetic protein 15 (BMP15) and growth differentiation factor 9 (GDF9) have been shown to be associated with POF. METHODS Genomic DNA was isolated from 52 idiopathic premat...

1. To recognize hypergonadotropic hypogonadism as part of the differential diagnosis of delayed puberty 2. To recognize premature ovarian failure as a cause of hypergonadrotropic hypogonadism 3. To recognize chemotherapy and cancer treatment modalities as etiologies of gonadal failure 4. To understand that it is hard to predict which patients will resume normal ovarian function after chemothera...

Polycyclic aromatic hydrocarbons (PAH) such as benzo[a]pyrene (BaP) are ubiquitous environmental pollutants found in tobacco smoke, air pollution, and grilled foods. Prenatal exposure to BaP causes premature reproductive senescence in mice, and other PAHs are transplacental ovarian carcinogens. Glutathione (GSH) is critical for detoxification of the reactive metabolites of PAHs. Therefore, we h...
