Who's Your Daddy?
The question of whether or not to connect donors and their offspring has yet to be aggressively addressed by the sperm bank community at large, but the issue is increasingly relevant.

"The industry is self-regulated," said Alice Ruby, executive director of the Sperm Bank of California. "The American Society of Reproductive Medicine recommends no more than 25 children from the same donor for a population of 800,000."

In a city the size of New York that could mean 250 offspring from one donor.

The self-imposed limit at the Sperm Bank of California is 10 families per donor worldwide, with each family free to produce as many offspring as they like from that donor, according to Ruby. But that sperm bank — the only non-profit one in the U.S. — is more conservative than most.
