Talk:Bruce effect

Language
The lead says, "In mice, pregnancy can only be terminated prior to embryo implantation..."

Problem: Pregnancy is defined as beginning at embryo implantation. You can't terminate what hasn't started.

I'm not sure how to re-write this to be accurate. The concept to be conveyed is that this effect can happen only somewhere in between conception ("Day 1") and the start of the pregnancy (day 4 in mice; equivalent of day 6 post-conception in humans or what's called day 20 on a last-menstrual-period basis).
