Our Members

Donor Sibling Registry membership has been growing steadily since our humble beginnings as a Yahoo Group back in September of 2000.

DSR Growth

The DSR is growing! 

As of January 1, 2024, the DSR has 5,118 total donors registered. 1,765 sperm donors and 3,353 egg donors. The larger number of registered egg donors is because facilities such as San Diego Fertility Center, Vios, Kindbody, Idaho Reproductive, Illinois Fertility Centers, and Oregon Reproductive Medicine are regularly writing the DSR into their parent/donor agreements so that connecting can happen right from pregnancy/birth. Imagine if just one sperm bank acknowledged the importance of these early connections and offered this as an option.
