Moreover, improvement of quality of scientific papers is necessary. For this purpose, criticism of published studies is a way to increase the quality of articles and make them clear. In Avicenna Journal of Phytomedicine, volume (5), issue (2), year 2015, an article entitled “Effects of aqueous extract of celery (Apium graveolens L.) leaves on spermatogenesis in healthy male rats” was published and the papers like this should be appreciated. However, the paper has some drawbacks which if not resolve, could be misleading for researchers who tend to use it or do research in its direction. So, with all due respect to the research team, we decided to evaluate the paper ambiguities in order to improve the quality of future articles.
