There is a growing theory that vegetarians and vegans are more likely to conceive girls. The same is true of women who eat low-calorie diets (check out the BBC on that one). In some of the calorie-related studies, that calorie disparity has been slight (i.e., women conceiving boys ate about 2400 calories a day, whereas women conceiving girls ate around 2250 a day).
So, what’s your experience? If you’ve also had boys, speak out. I’m just curious to see how true that theory holds here.

It’s the men who decide the sex not us:)

Yeah the only options to women’s contributions are X chromosomes, so those particular studies seem illegitimate.

it’s true that men are the only ones who can contribute a Y chromosome, but there are a lot of old wives’ tales and some scientific studies that say certain ueterine environments and/or timing can contribute to the likelihood of the X sperm or Y sperm reaching the egg faster. so maybe there is something about the diet that creates a more ideal environment for the X sperm?
all i know is that my friend who is vegan had a girl. =P

But isn’t it the man’s sperm that determins the sex of the baby?

I’m not either (I eat poultry and seafood) but I have two girls so maybe we’ll attribute it to a lack of red meat 🙂

I was told, in one of my college courses by a prof with a phd in the psychology and clinical study of sex that what actually determines the sex of a baby is the acidity of the woman’s vagina. So, a woman’s whose PH balance is more acidic is likely to have a female child bc female sperm can last longer in an acidic environment where make sperm do not survive in an environment where the PH balance is highly acidic. The prof did tons of research on it. I don’t remember all the legistics but I remember being in the class and finding her theories and research to be interesting and it all checked out.

My friend has been vegan her whole life and has 2 boys!

My cousin who’s a strict vegetarian is pregnant with a boy!

@bijou214: Yes, I have read similiar things. Apparently, sperm carrying X chromosomes (female) are slower (since they are heavier) than those carrying Y chromosomes but that they live slightly longer within the female reproductive tract. And that the consistency of the cervical mucus determines which sperm are able to swim better and reach the egg first.
So, maybe a woman’s pH (acidic vs alkaline) can have have a bigger impact than previously thought on the quality of her cervical mucus and, therefore, influence the gender of her baby.
I do remember one thing after reading Taking Charge of your Fertility http://www.tcoyf.com : that the best day to conceive a boy is on the actual day of ovulation, but if you want to conceive a girl, then have sex a day or two before ovulation.
By The Way, I was a vegetarian at the time I conceived and had a girl. 🙂

That study has been proven false….typically, having sex a couple days before ovulation has a TINY bit of a better chance of producing a boy, day of, girl.
In any case, the egg does have a ‘say’ in which sperm it accepts and the environment of the uterus/fallopian tubes also favor different sperm (high calcium diets=slightly higher chance of girl, high starch diets= slightly higher chance of boy, things like that…it’s not a huge difference). But if a sperm is deformed, the egg doesn’t have to bond with it and it will reject it. The egg has it’s own receptors that choose to bind with the receptors of sperm that it finds to be strong, that way there’s less chance of miscarriage. An egg won’t accept just the first sperm…often it takes a few sperm until one is “accepted”.
It’s pretty reasonable for people with different diets to be slightly more likely to have boys or girls, but in any case, the difference is minimal, maybe a couple percentage points in either direction. Vegetarians/Vegans will still have boys, meat eaters will still have girls.

@Holly77: Yes, I’m aware. I’m not talking about that. But the environment also plays a role in which sperm makes it home, in any case.

I’d like to point out that I’m aware that this is one study and not necessarily reflective of birth patterns as a whole. Yes, I’m aware that only men can contribute ‘Y’ and ‘X’ as well – that women can only contribute an X chromosome. That’s basic biology.
I was only looking for anecdotes. I’m not one who believes in restricting my calories to x amount a day, or eating a strictly vegetarian diet, convinced it will give me a girl – even the studies point out somewhat miniscule differences in the rates. We might be in dire straits if dietary differences could upset gender balances to a severe degree.

I’m not a mom or TTC, but I’m a long-time vegan and even longer-time vegetarian. This is so intriguing! I’m really curious about a potential link now.

@Mrs. Gremmlin: I’m a vegetarian, but definitely not for these purposes. I’d say that moms who are desperate for a girl are likely to be disappointed, but in any case, it couldn’t hurt – just like the millions of other theories out there about vaginal acidity/dietary restrictions, etc. It might boost your odds a bit, however slight.
