The two images accompanied bioZhena’s Weblog post “The perils of IVF, of ARTs, of giving birth at old age – part 2”, at http://biozhena.wordpress.com/2012/04/18/the-perils-of-ivf-of-arts-of-giving-birth-at-old-age-part-2/ . Gist: Tidbits from a debate at a LinkedIn group about DANGERS OF IN VITRO FERTILIZATION. And I offer Google Ngram evidence for why I was justified to exclaim, “Damn the bloody Pill”. People debate hotly burdening future generations with debt – but we don’t seem to care about burdening them with health consequences of the daft but so prevalent postponement of motherhood until it’s too late. Consequences, potential until experienced: Birth defects in IVF kids, and – theoretically, speculatively - epigenetic harm in subsequent generations of offspring. Do we really demand the direct human harm and suffering proof before reconsidering…? Is ambulance chasing the way?

When you enter phrases or key words into the Google Books Ngram Viewer, it displays a graph showing how many times those phrases have occurred in a corpus of books (here English-language books) over the selected years (here 1960 to 2008, last year of data availability). See Ngram 10 in “The perils of IVF, of ARTs, of giving birth at old age – part 2” at http://to.ly/d0iq . It shows the data for the number of books on IVF (blue) and for the number of books about the Pill (red). Books about the Pill appear and grow in numbers in the 1960s (when the Pill was launched in the market) while IVF books only appear some 10 years later. By 1980s the IVF book numbers grow fast and far exceed the number of books about the contraceptive Pill. Even more significantly, the IVF book volume does not exhibit a declining trend (such as occurs in the Pill data after 1980). IVF books continue to be written at a relatively steady rate, significantly higher in numbers than the declining books about the Pill.

... two World Wars, and the Great Depression in between. Those two generations had it tough but, on the other hand, their health, the health of humankind, was not yet assaulted by the sex-steroid chemicals that were introduced in the 1960s.
In a previous bioZhena’s Weblog post ( http://to.ly/5f2W ), you can see evidence that oral contraceptive use directly and negatively impacts the cervical crypts, which brings about the difficulty to conceive. The bottom line is this: “After 3 and up to 15 months of contraceptive pill use, there is a greater loss of the S crypt cells than can be replaced.” The S crypts are needed for conception.
