If eighty percent of human embryos are spontaneously aborted in menstruation
I would not rely on this data. No one has truly studied this, as they would have to examine large numbers of menstrual fluids from large numbers of fertile women who are on not using birth control. There is no money in this. There is money though in scaring women into believing that infertility treatments are needed because the natural chance of becoming pregnant is unlikely. Personally I feel the average female reproductive system is built better than only 20% of fertilized eggs being accepted by the womb. The female body is complex, but it is made to hold onto life with hormones and nutrients. Did you hear about
the woman who weighed 37 pounds at the time of conception?
And also, if a woman's body spontaneously rejects a baby, God's will is done completely. This is not an "abortion." It is as you imply a dead baby and should be respected as such. And I can think of no better tribute to that human life than for God to have decided that life had to take the shortest route possible to his kingdom and the last person the baby touched was his/her mommy.
"It is as you imply a dead baby and should be respected as such." This is where anti-Catholics start saying, "Do you require a funeral for a period?"
If only God knows whether a short-lived conception occured, then God can concern himself with that. I don't believe He places any burden on the mother. Which is not to say that possible abortifacients become acceptable, only that there is no burden in natural events.
