A reader writes: We do routinely offer emergency contraception to the victim

This is absolutely why Sarah Palin didn't pay for rape victims' exams in her city while mayor.

Dear John
I am a physician who has been doing these kits for 25 years. Although the process has changed a bit over the years, we have never collected fertilized ovum as evidence. This would be a very invasive procedure and, anyway, these kits are done within 72 hours of the rape during which time fertilization would not necessarily have occurred.
We do routinely offer emergency contraception to the victim.
Hope this helps
