Varicocele is known as dilatation of the pampiniform plexus of the spermatic cord and has long been thought to be related with male infertility. It is assessed that 10-15% of men and adolescent boys have varicoceles, and in men with irregular semen analysis, the occurrence of varicocele reached 25%. In fact varicocele is the most commonly seen and correctable cause of male factor infertility. The aetiology and pathophysiology of varicocele is difficult and likely multifactorial.
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.
