There are at least 10,000 test-tube children in the U.S. (some doctors estimate as many as 40,000). They have been born in the last 25 years as the result of artificial insemination, with the doctor using semen supplied by a carefully chosen anonymous donor. Their legitimacy has always been a matter for speculation. A Canadian court has ruled donor babies illegitimate, but in the U.S. the question had remained moot. Last week a tangled divorce and custody case projected it into the headlines...

Under the new system, the output of a desirable bull can be stockpiled in the frozen state and be ready for use at any time in any part of the world. None need be wasted because...
