For a long time, having children has been a young person’s game. Although ancient records are sparse, researchers estimate that, for most of human history, women most typically conceived their first ...

Sixty percent of miscarriages are caused by the failure of an embryo—the developmental stage before a fetus—to implant in the woman’s uterus. Part of the problem is that researchers have no idea how ...
