This is really interesting jj! Please post any more bits you might find:agree: So this info could add weight to the ewcm for boys thoughts as maybe it is definately the girls who can make it through the more hostile cm possibly????!
Agreed definitely interesting, if only they tested gender of the longest survivig ones too
Yes the gender results would have been interesting.
Was there/did I miss the health of the babies. If the baby was conceived on 5-7 days before Ov did it have problems?
I know DS1 was conceived the day before my period was due... little monster :)
That is def. interesting although the WHO info is not at all similar to what I've read. I would suspect that some of those numbers are inaccurate (as in, people did not ovulate when they think they did). A LOT of people do NFP and it's a very reliable method of birth control - this would not be the case if any large % of sperm stayed alive for many days.
ETA - here is just one set of data from FF "In a recent analysis of 119,398 charts from women charting with Fertility Friend, we found that 94% of women who became pregnant had intercourse on at least one of these three days. For conception purposes, it is thus ideal to have intercourse during a three day fertile window which includes your ovulation day and the two previous days. " The three days they mention are O-2, O-1, and O day. Plus there was a lesser but still significant number on O-3. That leaves a very small % for longer cutoffs and O+12.
I don't believe the numbers that were attributed to the WHO.
