The show was particularly wrenching, though, when juxtaposed with two recent dispatches from the world of midlife, upper-middle-class infertility. Last month there was Vanessa Grigoriadis’s provocative New York Magazine story “Waking Up From the Pill,” which suggested that a lifetime on chemical birth control has encouraged women “to forget about the biological realities of being female … inadvertently, indirectly, infertility has become the Pill’s primary side effect.” Then on Sunday, The Times Magazine provided a more intimate look at the same issue, in which a midlife parent, the journalist Melanie Thernstrom, chronicled what it took to bring her children into the world: six failed in vitro cycles, an egg donor and two surrogate mothers, and an untold fortune in expenses.

In every era, there’s been a tragic contrast between the burden of unwanted pregnancies and the burden of infertility. But this gap used to be bridged by adoption far more frequently than it is today. Prior to 1973, 20 percent of births to white, unmarried women (and 9 percent of unwed births over all) led to an adoption. Today, just 1 percent of babies born to unwed mothers are adopted, and would-be adoptive parents face a waiting list that has lengthened beyond reason.

Some of this shift reflects the growing acceptance of single parenting. But some of it reflects the impact of Roe v. Wade. Since 1973, countless lives that might have been welcomed into families like Thernstrom’s — which looked into adoption, and gave it up as hopeless — have been cut short in utero instead.
