Medical taking part in procreation in gamete and embryo donation is recent in France and has been included in the field of medically assisted procreation as defined by a law since 1994. Theses activities are strictly regulated. If procreation using donor sperm has been broadly carried out for 30 years in the CECOS leading to the birth of approximately 40,000 children, oocyte and embryo donation had a more recent and limited development. The main questions to which are faced the couples procreating through gamete and embryo donation is whether their child should be told about its origin since they have to build a parenthood and a filiation which are not first depending on biological and genetic links.
