@AstoriaK:  Thanks for bumping this! DH’s SA is scheduled right on O and he has to abstain for 48hrs. This gives me at least a bit of reassurance that we aren’t wasting a month.

Thanks for reposting! This makes me feel a little better we didn’t BD O+1 (or on O day if you believe FF, which I think is off by a day).

Super helpful – thank you!  I’m -3, -1, and 0…so toes and fingers crossed. 🙂

Interesting factoid related to this:

Since it’s the sperm that determines the baby’s gender, based on whether the sperm cell carries an X or a Y chromosome, you can try to time intercourse relative to ovulation to increase the chances of conceiving a girl or a boy. (There are no guarantees, of course, but you can work the statistical probabilities in your favor.)

The X chromosome is bigger and heavier than the Y chromosome (due to the difference in shape). As a result, “male sperm” carrying the Y are smaller, lighter, faster, and more fragile than the “female sperm” that carry the X, which tend to be bigger, heavier, slower, but also heartier and longer-lived. So, if you are hoping to conceive a boy, your likelihood of doing so is greatest right around the time of ovulation (within a day or two, as well as the day after). If you want to conceive a girl, you will have better luck if you time intercourse for several days before ovulation.

In Impatient Women’s Guide to Getting Pregnant, she cites that in a study of pregnant women 43% had BD’d on 1-O.   That was the only day we BD in my FW.

I was wondering about this today. My question was along the lines of how long can sperm live, and I guess it’s somewhat related to this post. 

It seems like 2 days prior to O gives the highest probability. Wow! I would think the closer you are to O the better. I think it takes some time for the little fellow to swim his way up lol!

@lovemygsp:  Glad to help by bumping! We only got O-4 in so I was trying to find out how likely it would be to actually get pregnant with that timing and these charts were really helpful. I thought other people might be interested, too!

@aliciapdx:  That’s what I read, but I don’t think the little fellow can survive as long, but I guess it all depends on the individual and circumstances. 😉

@candy11:  My OBGYN said at least 72hr but in some people (depending on CM and body chemistry) it can live long.

Why would 4 days before O be a higher chance of conception than 3 days before O…that’s good news for me this month, but it doesn’t make sense!

I’ve always wondered about this! Glad it has been bumped up. OP – thanks for posting, although it was a few months ago 🙂
