Making babies by any method other than the usual way is the immense subject of this book. It is not surprising that when procreation is moved from the bedroom to the lab bench, confusion is born. This author does an admirable job in weaning the confusion away from the tools so you can decide if you want to use them. I came away from her compassionate reporting with the distinct sense that new-fangled conceptions are a long lever bending our culture profoundly.
