International co-operation and dialogue in the field of fertility and sterility can be said to have truly commenced in 1951 in Rio de Janeiro with the formation of the International Fertility Association (IFA). Eminent scientists from various parts of the world became members and triennial World Conferences in Fertility and Sterility were organized, the first in New York, USA, in May, 1953.
At the Sixth World Conference held in Tel Aviv, Israel in 1968, the IFFS was born. The International Fertility Association remained as an affiliate to represent members with no national society. A constitution and by-laws were drawn up and remain today to govern the actions of IFFS.
Membership has grown and at present, over 65 National Fertility Societies are affiliated. It is estimated over 50,000 specialists worldwide concerned in the areas of fertility and sterility are brought together under one umbrella organization.
