People cared more about Aids and Alzheimer's, say, than had been expected. But the one thing that scored surprisingly low was infertility. Perhaps this is because we don't know what to think about childlessness in general, either enforced or voluntary, or how to place it. Until a few decades ago, it was regarded as a woman's function and duty to bear children if she married. To be a woman was to be a mother.
Men sow and women bear fruit.
The present gives birth to the future. If a woman had no maternal longings, that was her problem. On the other side of the coin, there was nothing a couple could do about problems in having children. And it was also a secret. Unnaturalness and incompleteness.
