Sooooo…. just wondering….. if DH and I have sex everyday (or every other day) starting 5 days before the O day, sperm from which one of these days is most likely to fertilize the egg? The one from 5 days ago or 3 days ago or the day right before O?
I have not been able to get an answer to this anywhere. This has just piqued my curiosity. I figure if the sperm can live up to 5 days in my body wth the right kind of CM, then which ones are likely to fertilize the egg?

@Sasha2011: The day before O would be the most likely though sperm I believe can live up to 4 days.

I think it depends entirely on the hardiness of his sperm and the environment inside you. I don’t think there would be any way to tell without doing some really elaborate test to see how long his sperm live, on average, in your business. And even then, that wouldn’t tell you which particular ejaculatioin had successfully fertilized your egg. Like maybe the ones from five days prior are still alive, but they’re too tuckered out to break into the egg.

@Sasha2011: Are you asking if a 5d, 3d, Od sperm are all waiting in the same place, which would fertilize?
I dont think anybody really knows the answer to that. (ALthough I have heard that sperm only last 3 days in your body.) The whole which sperm fertilizes is kinda a mystry. They dont know why sperm X makes it and ther other thousands dont.
The goal of having sex so often is to just have sperm there since the egg only survives 12-24 hours.

@KoiKove: This. My husband and I had sex on O-1 and O. I have no idea which day’s “deposit” did the trick, but one of them worked!

I think sperm from O day! On your O day, there will be a lot more sperm around from O-1 than from O-3 or O-5, because sperm ‘die’ off after a certain period of time. So if all sperm are equal, then just by probability, it’s more likely recent sperm fertilized an egg!

I’ve seen a chart that showed that people who had sex O-2 were most likely to get preggers. I’ll search the bee and see if i can find it.

I feel like regardless of day as it relates to your O date, it’s literally the fastest/strongest/closest single sperm to ovulate the egg. But I definitely may be wrong, there’s literally no scientific evidence I know or have read to support that thought.

Thanks bees! I was wondering that in general but also, once we have baby #1, I wanted to try for the other gender in baby #2. And we all know how unpredictable O day can be so I could be doing it back-2-back for a few days but might end up with an early or late O.
Aaaah! I need to stop over thinking this. NOW!
