Ovarian dysfunction or failure is common in premenopausal women receiving chemotherapy. Danger can be projected by the patient age and drug dosage. About 30% of women below age 35, 50% of women aged 3540, and 7590% of women in their 40s may experience permanent cessation of menstrual function after chemotherapy, leading to premature menopause.
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.
