For anyone who has experienced a miscarriage (or, even worse, miscarriages), this is a must-read book. From Cohen's extremely detailed but easily understandable descriptions of how eggs and sperm are created and how they meet to create a human being to the debunking of common myths (still held by most doctors), you won't be able to stop reading.
One's first surprise is how humans ever manage to reproduce at all when approximately seven out of every ten conceptions fail. The next surprise is that early home pregnancy tests can be as much a curse as an announcement of happy news. By now knowing just days after conception that they are pregnant, most women will likely "experience" early miscarriages that would have gone unnoticed or been regarded as simply late periods a mere ten years ago. More of these women will believe they have a problem conceiving when what they are really experiencing is the body's very normal method of maintaining only those fertilized eggs most likely to develop into healthy babies.
Cohen describes extremely intriguing cellular studies of conceptions from the first moments of fertilization to weeks after implantation to demonstrate what really happens when sperm meets egg and the many things that can go wrong. Almost all of the early failures are due to either problems with implantation (often hormonal or a matter of bad timing) or chromosomal defects that occur at the very first stages of cell division, which are infinitely more common than anyone knew before. Even more surprising is the finding that it's not the age of the woman's eggs that causes the development of more babies with chromosomal defects (most commonly Down's Syndrome caused by an extra copy of chromosome 21) but rather how close the woman is to menopause (something she probably wouldn't even know without a uterine biopsy). In other words, and most beneficial to women looking for answers, it's not the woman's fault. A miscarriage is not caused by that glass of wine she had at the office party or the 5k race she ran last weekend or the shocking news that a loved one suddenly died.
In addition, the author explains, through many double-blind scientific studies, that many, if not all, of the "treatments" physicians offer for recurrent miscarriages are useless except as "something to do". The only "treatment" shown to have real, repeatedly verifiable, effects is a warm and nurturing relationship between the woman and her healthcare givers throughout her pregnancy. The good news is that even for women who have experienced up to 8 or more miscarriages, almost all will eventually bring a healthy pregnancy to term.
And, finally, Cohen acknowledges that, for most women who experience even one miscarriage among several successful births, losing a pregnancy, even it's just a week or two after conception, is an emotionally sad event that can be vividly remembered one's entire life.
