Sperm donor reunites with some of children he fathered

SEATTLE -- A unique family reunion took place this holiday weekend between a sperm donor and some of the two dozen children he's fathered.

Five half-siblings met up with Dr. Todd Whitehurst in Seattle.

He was a sperm donor while in graduate school at Stanford University and now many of the kids are college-age themselves.

Every year, Whitehurst, who lives in San Francisco, meets up with some of his kids in a different city.

Whitehurst was contacted by the Donor Sibling Registry and started meeting the donor-conceived children years ago.
