Surrogacy and donor-conceived siblings: Connecting families



Surrogacy, especially when combined with egg or sperm donation, has the potential to create connections between families that would not have existed otherwise. This includes the relationship between donor-conceived siblings - children conceived with the same donor's egg or sperm but born to different families. Understanding this unique relationship and fostering a positive connection can add an enriching dimension to the surrogacy journey.

The Concept of Donor-Conceived Siblings

Donor-conceived siblings are children who share a biological connection through a common egg or sperm donor but are raised in different families. In surrogacy situations where donor gametes are used, the potential for donor-conceived siblings exists.

The Significance of Donor-Conceived Siblings

The significance of donor-conceived siblings varies widely among families and individuals. For some, the biological connection is important and worth exploring, while for others, it may not hold the same significance. There is no right or wrong approach - it largely depends on the perspectives and preferences of the involved families.

Connecting Families: Donor Sibling Registry

One way families with donor-conceived children can connect with each other is through the Donor Sibling Registry. This online registry allows people conceived through sperm, egg, or embryo donation to make connections with half-siblings and/or the donor. By providing a platform for communication, it facilitates an open dialogue and potential relationships among donor-conceived siblings.

Navigating Relationships among Donor-Conceived Siblings

Maintaining a relationship among donor-conceived siblings can bring about unique opportunities and challenges. These relationships can provide a sense of identity and belonging, but it may also raise complex emotions and questions. Each family must navigate these relationships in a way that best suits their circumstances and respects the feelings of all involved.

Age-Appropriate Discussions with Donor-Conceived Children

Discussing the concept of donor-conceived siblings with children requires age-appropriate communication. Younger children can be told that they have siblings who share a special connection with them, while older children can understand more complex ideas about genetic connections and the role of a donor.


The potential for donor-conceived siblings in surrogacy adds another layer to the complex and beautiful journey of creating a family. The connection between these children can be a source of enrichment and understanding, providing an extended sense of family and shared identity. However, it also requires sensitive navigation and respect for the feelings and experiences of all parties involved.
