چکیده

polycystic ovarian syndrome is a hetrogenous condition with a broad clinical and pathologic spectrum that may reflect the effects of diverse etiologic factors. polycystic ovarian syndrome is an abnormality in the maturation of the follicles which can result in abnormal composition of follicular fluid. by analysis and comparison of the biochemical composition of human follicular fluid in normal and polycystic ovaries, we undertook to find the etiology of arrested follicular development in this syndrome and to gain an insight into the role of biochemical constituents of follicular fluid on follicular development.the results of our study indicate hiher concentration of potassium, lower concentration of testosterone and higher level of ph in normal ovaries relative to polycystic ovaries. in conclusion, potassium and testosterone concentrations and ph level seem to be some of the most important factors in the oocyte maturation and the acquistion of follicular development; and changes in them may have important role in the etiology of polycystic ovarion syndrome.

ENVIRONMENTAL FACTORS AND POLYCYSTIC OVARIES

This study was designed to investigate the effect of environmental factors on the appearance of polycystic ovaries (PCO) during the first two decades of life. Ninety-four female-female twins who underwent a transabdominal ultrasound at the Royal Hospital for Women were sent a questionnaire asking about their birth details, feeding history as a baby, childhood illnesses and vaccination as w...

Anti-Mullerian hormone is increased in follicular fluid from unstimulated ovaries in women with polycystic ovary syndrome.

BACKGROUND Anti-Mullerian hormone (AMH) may have a role in disordered folliculogenesis in polycystic ovary syndrome (PCOS). Though there have been several investigations into circulating AMH levels in patients with PCOS, no previous studies have compared AMH concentrations in the follicular fluid of unstimulated ovaries in women with PCOS with that of normally ovulating women. METHODS Follicu...

An imbalance between apoptosis and proliferation contributes to follicular persistence in polycystic ovaries in rats

BACKGROUND Cystic ovarian disease is an important cause of infertility that affects bovine, ovine, caprine and porcine species and even human beings. Alterations in the ovarian micro-environment of females with follicular cysts could alter the normal processes of proliferation and programmed cell death in ovarian cells. Thus, our objective was to evaluate apoptosis and proliferation in ovarian ...

Bilateral Polycystic Ovaries.

The writing of an article about this condition presents considerable difficulties. It is found in a numbet of separate disorders and is not therefore an entity in itself, though a common final mechanism may be typically involved. Moreover, a number of matters are involved about which knowledge is confused, fragmentary or uncertain. It is proposed to consider various aspects of the subject separ...

The follicular excess in polycystic ovaries, due to intra-ovarian hyperandrogenism, may be the main culprit for the follicular arrest.

This review exposes the follicular abnormalities responsible for anovulation in polycystic ovary syndrome (PCOS). The putative pathophysiological explanations involve the principal intra- and extra-ovarian regulators which intervene during normal folliculogenesis to control the initial recruitment and growth and then the cyclic recruitment. We propose the hypothesis that the follicular problem ...

Hormonal and Biochemical Profiles In Follicular Fluid of Unovulated Follicles in Superovulated Goats Ovaries

The composition of follicular fluid (FF) varies with the cyclical hormonal changes and developmental stage of follicle. During superovulation programme, the large number of unovulated follicles is a major constraint and affects adversely the embryo recovery. An attempt was made to study the hormonal and biochemical profiles of unovulated follicles in goat superovulated with either Synthetic FSH...
