Is there a maximum number of times to donate?

The number of donations is subject to the Assisted Reproduction Law 14/2006 according to which the maximum number of children born in Spain that would have been generated with gametes from the same donor should not exceed six. 

For the purpose of the effective maintenance of this limit, donors must declare in each donation whether they have made other previous donations, as well as the conditions thereof, and indicate the time and the center in which such donations were made
