(Newser) – When Cynthia Daily, her partner, and their son vacation with other families, "it's wild," she says. The kids "all look alike." That's because Daily turned to a sperm donor seven years ago; using the number assigned to her donor, she later searched an online registry for her son's half-siblings, some of whom her family now holidays with. Turns out there are 150 of these kids, and that number is growing. While Daily's son's clan is one of the biggest groups of brothers and sisters to share one donor dad, it's becoming less of an anomaly, reports the New York Times, which says 50-plus-member groups are appearing more frequently in online registries.

The concerns are growing in number, too. Some worry of the potential for rare genetic diseases to spread throughout the population. Others fear the real possibility of accidental incest, as unwitting half-brothers and half-sisters often live near the same sperm bank—and each other. “My daughter knows her donor’s number for this very reason,” says the mother of one teen. "She’s had crushes on boys who are donor children. It’s become part of [her] sex education." Critics are clamoring for a legal limit to be imposed on how many kids one donor can father, and some blindsided donors may agree.

I told them I was captain of the football team, chair of the debate club, and editor of the law review at Harvard, but I was really just using the money to buy model airplane glue. One time I went in with both hands bandaged and asked the nurse to help me out.

These people are idiots. There is no other way to explain a behaviour that could have dire consequences for future generations And I don't think any less of the people that for a fee facilitates this activity.

Does anyone remember the "tradition" of royalty demanding to screw virgins on their wedding night, like in Braveheart? And we wonder why the English have weak chins and bad teeth! I do not think anyone's genes are so incredible that they need to propagate 150 children, and the chances of increasing recessive gene disorders in the population does increase with this practice. I think donor limits, at least for each country in which you donate, are a good idea.
