It would seem that Im jumping into the middle of an argument here so forgive me if Im not aware of what may have been discussed previously. I think one of the issues at hand with this article is the phrase substantially increased mid-term pregnancy loss. Statistically this could be just a few percentage points and it also refers to mid-term. Unfortunately rape victims may still implant and show pregnancy within the first few weeks. Im sure most such pregnancies are aborted before midterm and this may skew human data on the survivability of the embryo.
In plain English this journal appears to be saying that stress reduces the chance of a full term pregnancy. Personal antidotal evidence suggests this may be true since my girl friend lost 4 pregnancies with her ex-husband and she was very stressed during that marriage.
As far at this notion that if you were raped you shouldnt get pregnant - I dont know where that started but the idea is reprehensible (IMO).
Im sure most such pregnancies are aborted before midterm and this may skew human data on the survivability of the embryo. Actually, not. At least one study has shown that women who conceive through rape are less likely to have an abortion than women who freely choose to become pregnant.
Stress can reduce the number of implantations, and the number of early miscarriages (those that occur before the woman even suspects she is pregnant). That, along with the fact of physical injury caused by rape, decreases the chances of getting pregnant through rape. Stress can also cause later miscarriage.
