Portuguese law provides that gametes (spermatozoa and oocytes) are provided by altruistic volunteers. Before being admitted as donors to Ferticentro, donor candidates are subject to a rigorous process of evaluation of their health and fertility; those who carry a genetic disease or have a familial predisposition of any such problem are excluded.
Ferticentro has a sperm bank and a bank of oocytes of its own, in which there are hundreds of samples of donors of all ethnic origins, so that it is possible to assign a donor with physical characteristics as close as possible to those of the couple or receiving woman.
At Ferticentro we also work in a network with banks of international gametes, which we liaise with in situations of couples or women with less frequent physical characteristics than those found in the Portuguese population.
