Ending the anonymity of egg donors in shared donation programs could reduce the number of participants

The Brazilian Federal Council of Medicine seems to be increasingly flexible with regard to maintaining mandatory secrecy on the identity of donors.

This study aimed to evaluate if loss of egg donor anonymity could affect shared donation programs in Brazil
