This article aims to question the widely accepted idea that female university students in Spain have, in the past, tended to opt for degrees in the field of humanities. Based on an analysis of the official statistics that are currently available, the paper demonstrates that Spanish female university students showed a clear preference for scientific studies, first medicine and later pharmacy. This pattern was not affected by Franco's regime and remained stable until the great transformation of Spanish universities during the 1960s. Finally, the paper argues that the basic reasons for this preference for the scientific field were equal access to the prestigious male baccalaureate curriculum, which was a characteristic of the Spanish model for incorporating women into secondary education, and the uneven prestige of the professions to which the degrees provided access. The conclusion drawn is that, historically, pharmacy was the most common professional career pursued by female university graduates in Spain.
