Does taking progesterone reduce miscarriage risk?
Ask the doctor
Q. My daughter is 42 and pregnant. She has had one miscarriage. I've read that progesterone may help prevent another one. Should she take it?
A. Miscarriage is more common as women get older, and for women in their 40s, over 40% of pregnancies end in miscarriage. The vast majority of the time, there is nothing that a woman or her doctor can do to change this outcome. Most of these are abnormal pregnancies, destined from the moment of conception to result in miscarriage, which is nature's way of ending them.
