Women participation in Spanish sociological journals is analysed during the period 2001-2005, by means of bibliometrics and Social Network Analysis. There is a predominance of men (75,08% of authors) compare to women (24,92%), despite the fact that there is a majority of women ending University studies. This inequality starts to be perceived from the beginning of their research and professional development and it intensifies with time. As a result, only a reduced number of women reach the highest positions in the academic rankings, which correspond to authors with the highest productivity. Related to that, it has been observed a phenomenon of bottleneck, according to it as the number of women writers reduces, the productivity threshold increases. There must be studied in depth the barriers that make difficult the development of a professional course among women and to carry out a diachronic monitoring of the professional occupation and their contribution to papers.
