Let us guide you along week-by-week!)
It's been a while since I read up on the Shettles method, but if it is what I think it is (you have sex days before ovulation so only the stronger, female sperm survive?) then it worked for us. Not that we used it intentionally, but I ovulated extremely late in my cycle and it worked out that the odds were higher for a girl.
I have no idea how accurate it is for the boys (faster sperm - boy - reaching the egg quickly the closer it is to ovulation) because we didn't know anything about that when we had our boys - it just worked out that way.
It seems to have more scientific basis than some of the other things out there (the Chinese Lunar Calendar for example - which was incidentally, right for me lol!).
Good luck! I honestly thought this one was a boy (I think when you have two boys, you just expect a boy), so I was shocked when we were told it's a girl - and still a little worried that the ultrasound was wrong, even though she gave me her guarantee that it was definitely a girl lol!
my sil tried the shettles method & is due with her 4th boy in March.
i really think it's a crapshoot.
I think you still pretty much have a 50/50 chance. If it really worked, than most/all IVF/IUI babies would be boys! This is obviously not the case.
That being said, I don't know what we're having yet, so I don't know if the general theory was right for us or not.

Not necessarily - since IVF and IUI would put all sperm next to the egg, so it's a 50/50 shot. It's supposed to be the female sperm are slower swimmers, but survive more days, so it takes them longer to get to the egg - if they are put up next to the egg with IUI, they have as good a shot as the male sperm.
At any rate, I agree, I don't think it's entirely accurate - just possibly a slightly better chance for one gender over the other.
We tried Shettles for a boy but I won't find out if it worked for a few more weeks.
I hope it did.
I asked my OB about the Shettles Method and his response to me was, "Don't you think if it worked that I would have a son?" He has FIVE daughters. lol
According to that I should be having a boy but I'm having a girl. It might work for some people but it's clearly not going to be a sure thing.
EDIT We only had sex on the evening of ovulation and the morning after.
Most research I've read on Shettles has debunked it.
If I went by Shettles, I *should* be having a boy since I was tracking ovulation and timed sex as closely as possible. She's a little girl. I wasnt using the Shettles method, just the "best chance of getting pregnant this month" method.
t.bird:my sil tried the shettles method & is due with her 4th boy in March.i really think it's a crapshoot.
I agree. I think it's 50/50 any way you spin it.
I know someone who swears by Shettles and she has a boy and girl, and got the sex she "wanted" using shettles. I tried it, and I also tried some other OWT, but I'm not so sure about how accurate it is. Also, we don't know what we are having yet (though I'm pretty sure it's a girl).
But the Shettles method also says that because the male sperm are so fragile that some men who work in certain fields can only have girls, because their work situations kills off all their male sperm.
But I wouldn't put much stock in this.
It is nonsense to say the Shettles Method "worked" because you got a girl. You have a 50/50 percent chance in the first place, so while have the couples who try it get their way, that doesn't mean it works.
I read the book "The impatient woman's guide to getting pregnant" and it has an interesting chapter on gender choice. It says that research has shown that the Shettles method is actually more likely to give you the gender that you didn't want! Research shows that with the right combination of timing (which is silly if you want to optimise your chances of conception) and food choices (extra calcium for a girl, I believe), you can change your odds. But it would be something like 53/47, not anything to base your nursery theme on.
Never tried it, though I know people who have. I don't buy into it.
Various claims have been made for methods of selecting the sex of the infant through the deliberate timing of intercourse. Shettles and Rorvik recommend that couples who wish to have a boy should time their intercourse to coincide with ovulation, with up to 85 percent success claimed for the selection of boys and 80 percent for the selection of girls.25 In contrast, Zarutskie et al. concluded in their review of the published literature that if there is any tendency, it is for more females than males to be conceived when coitus occurs close to ovulation.33 We previously reported a possible association between the sex of the baby and the length of the follicular phase.34 However, we found no association between the sex of the baby and the timing of intercourse in relation to ovulation. We conclude that the deliberate timing of intercourse around the day of ovulation has no practical value in sex selection.
In summary, we have described the fertile days of the menstrual cycle for a group of healthy women. By analyzing data on the day of ovulation (identified by means of hormone assays of daily urine specimens) and daily records of sexual intercourse, we found that all conceptions resulted from intercourse that occurred during a six-day interval ending on the day of ovulation. The sex of the baby was not related to the timing of intercourse in relation to ovulation.
and more... (I looked this up when my friend told me about it, so I know the key words to google already if your wondering why I have this off the bat haha).
Editor?The widely held idea that spermatozoa bearing the Y chromosome (Y sperm) swim faster than those bearing the X chromosome (X sperm) seems to have originated from Shettles's work in 1960, using phase-contrast microscopy.1 He claimed to have observed ?two distinct populations? of spermatozoa.1 After attempting to count the chromosomes, he concluded that the smaller heads contain the Y and the larger the X chromosome. There were no intermediate types.1 The following year he reiterated these findings, adding that smaller headed spermatozoa can migrate more rapidly and fertilise the egg more often in the distal part of the tube.2
Reading Shettles's reports in Nature and other peer reviewed journals, many researchers thereafter believed that Y sperm swim faster than X sperm. The finding particularly influenced research on sperm separation.
Although several attempts have been made to correct this impression, it was not until the development of computer assisted sperm analysis (CASA)3 that reliable observations could be made. So far, researchers have found no morphological differences between human X sperm and Y sperm.4 Neither mature sperm nor their precursors possess significant morphological differences between X and Y genotypes4; and Y bull sperm do not swim faster than X sperm.5

A.C.Soup!!!:I was wondering if any of you used this method and it worked? I have two boys and would really love to try for a girl. Many people had mentioned "Shettles Method" and wanted to see if it holds any truth.
(I hope I don't sound too creepy)
Hey! Weren't we on the tri boards together way back when - I believe you were on bedrest for a good part of your pregnancy? Anyhoo, just wanted to sy congrats on the 2nd LO - Hope you are doing good :)
