Current Problems in Fertility : Based on the IFA Symposium Held in Stockholm, Sweden, April 2–4, 1970. Sponsored by Åhlen-stiftelsen, Sven Och Dagmar Saléns Stiftelse, and Roland Lundborg, M.D.

The tremendous increase in the output of scientific articles on reproduction Is symptomatic of the growth of science within this field. Last year about 20. 000 tItles were listed. There is, conse quently, a need for limited meetings, where actual problems in re production can be surveyed and discussed openly. In the IFA sympo sium in Stockholm 2-4 April 1970, 120 delegates from 18 different countries took part. The papers discussed on this occasion all have great general interest in the field of reproduction.
