Miscarriage and Hormones

I've always wondered if my miscarriages were mainly due to hormonal imbalances. Here is an article that seems to support that, in many cases, miscarriages have a hormonal component:

Hormones predict miscarriage risk

Here is an excerpt from the BBC News Article (link above):

"At as early as six weeks' gestation, levels of three placental hormones - inhibin A, hCG and oestradiol - were up to four times lower in the women who went on to miscarry compared with the women who subsequently had a live birth.

These hormones are known to be critical for the embryo's nourishment and development.

Professor Jauniaux said: "If we are able to identify these clear hormone variations early enough, we believe there is a real window of hope for the development of preventative therapies for these patients."
