Professionals in the field of sexual pharmacology research gathered at the international symposium organized by the Esteve Foundation on October 9-12, 1994 in Majorca with the purpose of seeking answers to related issues. How can pharmacology contribute to clinically improve a number of existing sexual problems? What are the repercussions on the sexual function secondary to the use of drugs for the treatment of other diseases? These are some of the aspects included in the submissions of studies performed both in animals and humans, and compiled in volume number 6 of the Esteve Foundation Symposia series, edited by John Bancroft from the Royal Edinburgh Hospital.
