So I like scientific articles and science in general (I’m a doc), and I’ve been researching TTC information (from reputable sources e.g. medical journals). This article is very interesting and I thought I’d share with you all. It explains timing of BD in relation to O, and also talks about whether the sex of the baby could be influenced by timing of BD.
For those who are not into reading the entire thing, here are some interesting key points that will help with timing BD, especially if you know when you ovulate: from this large group of women who were TTC, no pregnencies resulted from having intercourse the day after ovulation. The chance of conceiving is highest on the 2 days leading to O and on the day of O. Only 6% of pregnencies could be firmly attributed to sperm that were three or more days old. Cycles producing male and female babies had similar patterns of intercourse in relation to ovulation. Nearly all pregnancies can be attributed to intercourse during a six-day period ending on the day of ovulation.

@sovix: Thanks for the great info! I was just wondering what our chances were since we BD’d on the day I had a positive OPK. We were hoping to BD a couple days before, but I ended up getting sick and DH had to work overtime (till 2am one night). I’ll definitely remember this next month if we don’t get a BFP! Thanks again!!!

Very interesting article…. have you found any others about natural sex selection? This is something I’ve been researching a lot, but I’m finding contradictory info.

@sovix: Thank you for this! I feel like there’s so much sketchy info out there about this topic; but the NEJM is as solid as it gets.

Glad it helped! This is the most clear article I’ve found.
Regarding sex selection, it seems that there were slightly more girls conceived on the day of O compared to a few days before O, but this was not statistically different. Plus, these could be chance findngs because the sample wasn’t that large. The authors concluded that there is no difference between girls and boys babies in terms when you have intercouse.

Thanks for that update. When I asked my OB about sex selection, she said “You’ve got a 50-50 chance no matter how you look at it.” Here’s to a healthy baby!

Very interesting!! We are on month 6 with (known) issues: almost no cervical mucus, very low bbt, and shorter-than-average luteal phase. We are babydancing every other day! Hope we catch that little egg.

As a scientist, I love seeing people look to legit journal articles instead of all the conflicting random sites all over the internet. 🙂

@sovix: thanks for this, and especially the summary – it is great to read ‘real’ research!!
happily, all of this is in line with most things I’ve read here on the bee and other websites 🙂

Thanks for sharing. What is BD?

Very neat 🙂 I’m one of the 6% who conceived with sperm older than 3 days -we had sex 5 days before I ovulated 🙂 Yay for super sperm!

Baby dance, I think, someone correct me if I’m wrong.
