does shuttles method work? x

Unless you had an ultrasound to pinpoint your DAY of ovulation then you do not know when you really got pregnant. You can only get pregnant around ovulation time, so it is normal for all pregnancies to occur around about O day. :)

I have 3 of 4 boys conceived with very regular cycles and cutoffs (one was an oopsie right after I got off AF, one was that we were TTC but my husband changed his mind and we stopped BD before we thought I could possibly get pregnant, one was a true Shettles attempt and my husband was actually away for the weekend when I ovulated. the other boy was a sneak attack and I have no idea when I BD with him) Then I got my daughter very late at night the day before O day (and my O was confirmed by ovulation) and that would be a Shettles boy timing.

So for me, 4 Shettles opposites.

On the other side I thought maybe it can work in terms of "sperm reduction"??? Or does sperm reduction has to occure already in the testicles???

To clarify, SOMETHING about the way Shettles is/was done seems to work for people and that is why it has endured. But it's NOT the timing of the BD and that has been proven, I believe, beyond any reasonable doubt. Timing intercourse does not work, it doesn't sway.

Sperm numbers may sway to some extent (so a long cutoff might possibly sway) but MOST importantly, our data is showing that one attempt sways pink big time. And since Shettles was always done with one attempt, it is very likely that the perception that Shettles worked was because the one attempt and not becuase of the cutoff. So, what we are doing now, with good results, is putting that one attempt on a day of the cycle where the odds of conception are good and getting 70% success for pink with that.
