Until the last two decades or so, secrecy reigned in the world of sperm donation. Few sperm banks provided access to information about donors and many advised parents to keep kids in the dark about their donor-conceived origins. But now, more donors are opting for transparency. That shift, coupled with direct-to-consumer DNA testing, has made it easier for offspring to find their donor dads and half-siblings. We'll talk to one donor about his experiences connecting with his 17 adult kids and we want to hear from you: what has been your experience with donor conception? Have you connected with a donor parent or child? Please share your experience.
