Well, you do need egg to meet sperm for conception to take place, so that would be impossible. But assume you are talking about intercourse taking place 7 days prior to ovulation? Well, so far as I know, 5 days before ovulation is the earliest. Don't know where this 10% figure came from. A couple with no known issues aged 25-35 has 20% chances of conceiving if they bd every 2-3 days in the fertile window which is the day of ovulation, the day after ovulation and up to 5 days before ovulation. Sperm will only live if they make it to the uterus, which is less hostile than the vagina.

Agree w/ Mammoth. Sperm can live up to 7 days, but that is the max and that is not all sperm. It depends on how healthy it is and other factors. Also, sperm starts dying off after 2-3 days so there's not going to be many left after 7 days. So it's possible if you BD 7 days before O to get pg, but I don't think it's very likely.
