Polycystic ovary syndrome PCOS is a common reproductive and endocrine disorder affecting up to 17.8% of reproductive aged women [1]. It is a life-long condition and although the exact cause is yet to be identified, it is believed to have genetic origins, influenced by the uterine environment and behavioural factors [2]. PCOS presents with irregular menstruation and/or signs of hyperandrogenism ...
Primary ovarian insufficiency (POI) is a clinical spectrum of dysfunction. Overt POI presents with oligo/amenorrhea and hypergonadotropic hypogonadism before age 40 years. involves chronic health problems to include increased morbidity mortality related estradiol deficiency the associated osteoporosis cardiovascular disease as well psychological psychiatric disorders loss reproductive hormones ...
The relative capacities of oligodeoxynucleotides, covalently linked to cellulose, to bind estradiol receptor complexes (E2R) of mouse uterine cytosol have been shown to follow the order oligo(dG) > oligo(dT) greater than or equal to oligo(dC) > oligo(dA). The E2R . oligo(dT)-cellulose-binding reaction is more sensitive to Cibacron blue F3GA than is E2R . oligo(dG)-cellulose or oligo(dC)-cellulo...
Functionalizable synthetic molecules with nanometer sizes and defined shapes in water are useful as molecular scaffolds to mimic the functions of biomacromolecules develop chemical tools for manipulating biomacromolecules. Herein, we propose oligo(N-methylalanine) (oligo-NMA) a peptide-based scaffold minimal structure high density functionalizable sites. Oligo-NMA forms shape without hydrogen-b...
BACKGROUND The risk for amenorrhea following treatment of systemic lupus erythematosus (SLE) patients with low-dose intravenous cyclophosphamide (IVCY) has not been fully explored. Our objective was to ascertain the incidence of amenorrhea following treatment with low-dose IVCY and the association between amenorrhea and the clinical parameters of SLE. METHODS A case-control retrospective stud...
BACKGROUND Secondary amenorrhea is a condition in which there is cessation of menses after at least one menstruation. It is a symptom of different diseases, such as hormonal disturbances which range from pituitary to ovarian origin, as well as chromosomal abnormalities. Knowledge of the distinct cause of secondary amenorrhea is of tremendous benefit for the management and monitoring of patients...
Animal studies indicate that gonadal hormones at puberty have an effect on the development of masculine and feminine traits. However, it is unknown whether similar processes occur in humans. We examined whether women with anorexia nervosa (AN), who often experience primary amenorrhea, exhibit attenuated feminization in their psychological characteristics in adulthood due to the decrease/absence...
BACKGROUND Primary amenorrhea due to 46,XY disorders of sex differentiation (DSD) is a frequent reason for consultation in endocrine and gynecology clinics. Among the genetic causes of low-testosterone primary amenorrhea due to 46,XY DSD, SRY gene is reported to be frequently involved, but other genes, such as SF1 and WT1, have never been studied for their prevalence. METHODS We directly sequ...
Secondary amenorrhea in women of reproductive age may be an indication of an undiagnosed, chronic condition and appropriate treatment is dependent upon accurate diagnosis of the underlying etiology. A thorough clinical assessment and a few common laboratory tests can easily identify the most frequent causes of secondary amenorrhea. However. in these cases, misdiagnosis is unfortunately common a...
