Reproductive toxicity is the condition generated by some chemical substances that interferes with the normal process of reproduction in the human body. It includes the adverse effects in the sexual functioning and fertility of males and females as well as responsible for the developmental toxicity in the off springs. There are many chemical substances that are found to be detected for causing reproductive toxicity. One of the well known groups of substances which are toxic for reproduction is known as Teratogens that causes birth defects. Another group of substance includes endocrine disruptors that cause reproductive toxicity. However, there are many substances that are known to be toxic for reproduction but do not fall into either of these categories like lead compounds. Recently the reproductive toxicity has focused its study on the aspects of occupational and or environmental exposures to the hazardous chemicals; and their effects on the reproduction and developmental biology.
High-impact journals are those considered to be highly influential in their respective fields. 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.
