He help develop Norethisterone, a synthetic hormone that eventually made the pill possible.
Recently, in an Austrian magazine, he lamented the demographic catastrophe which the Pill has brought:
Djerassi outlined the "horror scenario" that occurred because of the population imbalance, for which his invention was partly to blame. He said that in most of Europe there was now "no connection at all between sexuality and reproduction." He said: "This divide in Catholic Austria, a country which has on average 1.4 children per family, is now complete."
He described families who had decided against reproduction as "wanting to enjoy their schnitzels while leaving the rest of the world to get on with it."
The fall in the birth rate, he said, was an "epidemic" far worse, but given less attention, than obesity. Young Austrians, he said, were committing national suicide if they failed to procreate. And if it were not possible to reverse the population decline they would have to understand the necessity of an "intelligent immigration policy."
I think we shouldn't blame the Pill, alone.
After all, the outlook made it possible to accept artificial contraception, preceded the Pill.
If the Pill hadn't been invented, we'd probably still have a demographic crisis on our hand. The birth control would just come in a different form.
