The Results Are In

The results of the great cereal/sex study are below. But first, I have to give credit where due! A huge thank you to the lovely Beth at I Should Be Folding Laundry. She did my incredible blog makeover, changing me overnight from boring black to fabulous. You can see more of her designs at BeDesign. As if that wasn't enough, she also sent her readers over to boost my research numbers. You are all awesome - thanks!

A few of you asked about why mom's diet would impact the sex of a baby at all. We all know that it's dad's little swimmers that determine the gender question. Well, make sure you are sitting down because this is good. Apparently, while dad's sperm has the X/Y code thing going for them, the father's contribution does not dictate the outcome. That's right, you heard me. The EGG can pick the sperm of her choice from among the likely candidates. Think Bachlorette coming to a fallopian tube near you. The lady gets the final say.

Here's my lay (giggle) interpretation of some biology - hopefully no one reading this is a real scientist. The egg has a membrane that can reject potential sperm suitors in favor of others. I really like this part. Girl embryos are a little hardier than boys. Girls are a little more likely to survive in slightly less than ideal conditions. Boy embryos are a little higher maintenance and do better in cushy quarters. If for example, there are less available resources, like lower blood sugar (due to skipping your healthy special K breakfast), eggs favor girl sperm slightly.

Um, what was that about the weaker sex?

Here's the salient point: In just slightly less than ideal conditions, the egg can reject her Y carrying sperm visitors and opt for the tougher, more resilient girls.

Is anyone else picturing this or am I just weird? The lovely Eggwina exits her ovary all dressed up and looking for a decent sperm. Y sperm sidles up to Eggwina at the Ovary Bar downtown, Fallopian Tube.
Y sperm: Hey, you're looking gloriously ripe for fertilization this evening, want to make a beautiful boy together?
Eggwina: You look like a nice Y, but conditions are a little harsh these days, what with all the coffee and no decent breakfast. I think my chances are better with an X.
Y sperm: Sweetheart, I'm tough. Check out this genetic material. I can take a little low blood sugar.
Eggwina: Yeah, big man, I'm sure you are. But, I need code with a little resiliency and staying power. I need a sperm that can take the heat. I need girl sperm.

Some visuals:


Last one, I promise.


Okay, okay. The original study found that 56% of woman in the 'high energy intake' category had boys. Cereal bumped that up even more. 59% of woman eating cereal daily had boys. We blew them away, my friends. Even with a margin of error for some iffy variables like questionable counting on my part, twins (not sure whether to count once or twice) and unclear breakfast choices, we have proven that cereal equals more boys. I counted ninety-two kids total. Out of fifty-one children conceived under the influence of cereal - 76% boys!!!! Forty-one conceived not under the influence of cereal - 63% girls!!!! Wow.

I love the new blog design!

Nice drawings too!

I had two boys and then two girls. i think I probably was eating better during the first to pregnancies, by the third and fourth just getting food down was an accomplishment!

Fun post!

Love your new design:):): It's darling!

According to the Proceedings of the Royal Society B:Biological Science, a recent study of 740 pregnant women found that those who ate more at the time of conception and whose diets had a broader range of nutrients, particularly potassium, calcium and vitamins C, E and B12, were more likely to have boys. Women who ate breakfast cereal were also more likely to have boys.

Researchers aren't saying that a dad's sperm doesn't determine its sex. What they think is that mothers may be able to favor the development of one sex infant rather than another. In IVF, for instance, high levels of glucose encourage the growth of male embryos and inhibit female embryos.

So yes --- the egg membrane can reject potential sperm suitors unless it's IVF and they do ICSI where hey inject sperm into the egg and then it's up to the embryologist to pick girl or boy sperm:)

I love your illustrations! Great "lay" interpretation (coming from another lay[wo]man) - it makes sense now! ^_^ And finally proves to the world that girls are tougher than boys! We knew it all along....

well that's pretty neat.

thanks for your comment today.

Well, I don't know what your original design was, but I love the new one! I would have never found you if it wasn't for Beth. Thanks for the comment today and for the "educational" lesson. Very interesting indeed.

Thanks - I adore it. My old one was pretty much plain black. I had no idea it could be so cute.

And Diva, you are a scientist aren't you?? Thank you for not mocking me!

Oh my god your graphics rock! Hope to see you Thursday.
