The desire to bring new life into the world runs deep in human nature. We know instinctively that children are worthy of the greatest care, and that the mission of parents is among the noblest in life. If our natures did not tell us this so strongly, the pain of childbirth—with all the toil, trials, and heartbreak that follow—would never seem worth it.
The pain of unfulfilled desire for children runs equally and correspondingly deep. In Jewish and Christian Scripture, infertility is almost a byword for anguish, much as having children is a byword for joy, chief among the blessings of God (“Your wife shall be like a fruitful vine…” “The barren wife shall bear seven sons….”). From the beginning of our species to its present, the importance of raising and forming the next generation has been self-evident to all generations.
