What do you think of this timing method?

Ok, so another thought on this:

If there is any theory is shettles, dtd away from ovulation, PH killing or freezing y sperm, then if we dtd un-protected on cd9, and then I ovulate on cd17 - thats a 8 day cut off - so pregnancy is unlikely but if it happens, hopefully it would have been x sperm who survived. Then if we also dtd on positive opk on cd 16 then again thats a 7 day cut off so both times should have a lower sperm count. If I happen to ovulate earlier, like cd 14 - rarely happens, then we wont dtd and just hope the sperm made it from cd9.
Does that make sense?
Is that better than not having intercourse at all, or use condom on cd9, and then dtd on positive opk? I guess Im doing a bit of shettles but a back up intercourse on opk to give good chances of pregnancy ........... but with a 7 or 8 day abstinence in between. I just dont know which study to trust so thought Id try both together.

Also, do I just take sudafed 2 hours before dtd at positive opk, or at all attempts?
What is the maximum amount of times to take sudafed for swaying?

Ill get there eventually in my plan, the more I read the more I change my thinking and plan

XX and XY sperm live the same amount of time (Shettles was wrong in his assumption and mistook capacitated and uncapacitated sperm for XX and XY - he didn't test it, see point 2/3 here: http://genderdreaming.com/forum/show...rm-and-Y-sperm ). After 7 days or even 5 days you would have less surviving sperm in there, but chances are they would still be close to 50-50 XX and XY.

With a cut off of 5 days you have less than a 10% chance of conceiving each cycle. Obviously with a 7 day cut off it will be very very unlikely especially if you are doing other things to lower sperm count and decrease fertility. If you want to conceive fast (which I think I remember you saying you did) a cut off is really not the way forwards...

I think it's safe to DTD on the pos OPK - in fact that seems like the best option according to the majority of studies.

Here's a chart from a study of 200 women:

(Full study here: http://www.nejm.org/doi/full/10.1056...99512073332301 )

The fact that so many of the studies find different things about timing means that it most likely does not sway at all. The diet seems to be the most important thing and you said you're already doing that?

Thanks so much, thats been so helpfull!

Bumping this up just so more people can see the chart that rainbow posted. Not only is it a great chart but it comes from a well-designed study as well.

I am planning on getting that tattooed onto myself at some point in the future (not really!!!)
