The focus of the Donor Sibling Registry (DSR) is to assist individuals conceived as a result of sperm, egg or embryo donation who are seeking to make mutually desired contact with others with whom they share genetic ties. This may include:
Their own or their child's half-siblings, or
their own or their child's genetic father or mother, or
their own genetic offspring.
Egg, sperm or embryo donors who are willing to have contact with the children born as a result of their donations are VERY WELCOME!
