Accor- dingly, until fairly recently it was a medical act with a limited scientific basis which was practised more or less clandestinely. The development of semen preservation has totally changed the conditions of artificial insemination, especially in regard to flexibility and safeguards in its application. Although the use of fresh semen continues, it is now clear that the future of arti- ficial insemination is closely linked to semen preservation. During the past two decades, semen banks have been developed in many countries. This has most often been the result of the initiative of individual physicians in either the private or public sectors. In France, a national system of semen banks (CECOS) was begun in 1973.
