Donated: So far, Gordy has visited Denmark, England, Germany, Mexico, Scotland, and Sweden to donate sperm. In the U.S., he’s provided donations to people in California, Colorado, Arizona, Oregon, Kansas, Alaska, Seattle, Florida, Pennsylvania, Illinois, Hawaii, and North Carolina, according to the Daily Mail.
He makes the donations via artificial insemination using his sperm or through sexual intercourse, which he says accounts for about 10 percent of his donations.
Gordy stays in contact with the families he’s helped get pregnant, and he’s met at least nine of his children in person. In fact, he manages a group chat dedicated to the mothers of his kids, who use the space to talk and exchange photos and videos of their children, who are all half-siblings, he said.

"For those wondering about the nitty-gritty of it all, the dad has been open about providing women with fresh samples of sperm, often in a menstrual cup that they will then insert themselves, though in the past he said he kept it old fashioned.
The 44-year-old has also weathered some criticism and controversy, with five women successfully suing Ari for child support and some raised eyebrows after he donated to an 18-year-old woman living in a homeless shelter back in 2018."-

Donor: "Louis"
Origin: Dutch
Donated: From 1982 for 20 years (3x weekly to three clinics); donated until he was in his 50s.
"Louis" admits to dropping out of university, working at a bank, and failing in a number of relationships. He felt that he must be a bit autistic because he found it hard to connect with people so he decided to donate.
He openly admits to lying at least once in his qualifications. “It said I was university-educated, that I was a boss at a bank and that I had no interest in being contacted by future children,” he says. “The pharaohs built pyramids,” he says. “These children are my pyramids.”
One online sibling registry believes there could be up to 1000 children. Children of his have reported encountering other half siblings multiple times on Tinder, the dating app and those are only the siblings they know about.
