Can't answer; I'm not a scientist. But as for your earlier post, I said that I do err on the side of caution ("I'm not going to go out and get shot up with Depo-Provera" which is a birth control injection). I do, however, believe that birth control should be and should remain legal, and I think conflating it with abortion does the pro-life movement a huge disservice.

you don't have to be a scientist to know the difference between birth control and abortion.
"birth control" : NFP, condoms, vasectomy, tubal ligation, spermicide, sponge.....
abortificants: hormonal pills, shots, and patches, IUDS
the pro-life movement is exactly that - pro-life.
When there are practices that result in the death of human beings it is necessarily a "pro-life" issue.
