|Polycystic Ovary Syndrome (PCOS) is the most common endocrinopathy of women of reproductive age and the most common cause of anovulatory infertility in developed countries. Diagnostic criteria, as suggested in the Rotterdam Consensus Statement (2003) include (i) oligo- and/or anovulation, (ii) hyperandrogenemia and/or
hyperandrogenism (clinical signs of high androgen levels: hirsutism, acne, alopecia) and (iii) polycystic ovarian morphology on ultrasound examination.
The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
