[Psycho-sociological profile of a series of 850 sperm donors].

We present a retrospective study on a series of 850 sperm donors who came to CECOS-Lyon for the last 17 years. This study allows to determine different parameters on the social situation of donors: age, socioprofessional category, number of children etc. The donor population presents a great homogeneity in its constant renewal. From these data it seems easier to adapt the information messages to a certain population of men to make them aware of sperm donation.
