August, 2014 | INT BRAZ J UROL doi: 10.1590/S1677-5538.IBJU.2014.04.01 40th Edition The International Brazilian Journal of Urology was founded in 1971 with the name of Jornal Brasileiro de Urologia (Brazilian Journal of Urology), official organ of scientific publishing of the Brazi- lian Society of Urology. It represented the realization of the Brazilian urologists dreams: the development of their own scientific journal. Since 1927, the year in which the Society was founded, the idea of a scientific magazine was pursued with frustrated titles as “Clínica Urológica” (Urologic Clinic), “Archivos Brasileiros de Clínica Urológica” (Brazilian Archives of Urological Clinic) and “Revista Brasileira de Uro- logia” (Brazilian Magazine of Urology), that were discontinued (1). In 1973 it was published almost by hand (which is considered the number zero edition) the Jornal Brasileiro de Urologia (JBU) (Brazilian Journal of Urology), but only after January 1975 the journal started to be printed continuously, under the leadership of Alberto Gentile, who was considered the founder of JBU and his first editor, then called editor-in -chief (1). Due to the growing internationalization, in 2000 the name of the journal was changed to Brazilian Journal of Urology, including articles in English and Portuguese, and in 2002, it was adopted the name International Brazilian Journal of Urology (IBJU), including all articles in English. Ten years ago IBJU was indexed at PubMed/Medline and became an open access journal with free access to all articles at www. brazjurol.com.br. IBJU has some aspects that distinguish it from other magazines: likewise, all articles are submitted to a blind peer-review and primarily publishes original articles, reviews, challenging clinical cases and vide- os. It pioneered the publishing of the Video Section. On the contrary, it is a free access magazine that does not charge the authors including the translation to English of the Portuguese submitted articles. We have reached the 40th Edition, and thirty-eight countries are being published, with a median of 700 articles of submitted papers per year. There is a renowned Editorial Committee and many reviewers of all over the world, to whom we thank for their voluntary effort for reviewing our articles free of charge. IBJU philosophy is to publish well conducted articles and researches, interestingly to urologists, whether or not the article will be cited; we have increased the number of published articles per year, with a lowering of our impact factor, in order to accommodate more papers, to attend the authors who seek IBJU. We know that investigators must publish their work in order to disclose their findings and to excel in the scientific community, the main reason of the existence of a magazine. I am sure that the dreams of the Brazilian Society of Urology pioneers were accomplished. IBJU is worthy of pride by the Brazilian urologists and is earning a growing place in the international urological community. RefeRence 1.

The methods on how the human semen should be evaluated are provided by the Analysis; Andrology; Diagnosis; World Health Organization, which periodically releases manuals that include specific Spermatozoa; Reference Values; protocols and reference standards. In 2010, the WHO published new criteria for human Therapeutics semen characteristics that were markedly lower than those previously reported. In this review initially it is discussed the limitations of semen analysis as a surrogate measure of a man’s ability to father a pregnancy. Secondly, it is analyzed methodology issues Int Braz J Urol. 2014; 40: 443-53 that could explain why the newly released reference values were different from those earlier reported.
