crashing... they have lots of gender specific info related to diet prior to conception affecting gender at ingender.com.
I did do alot this time diet wise for gender swaying. But won't know if it "worked" until baby is born :) And as far as cravings go, I don't get any during pregnancy really so can't comment on that part.
Hmm, I haven't heard that theory, about the varied diet. I know when I got pregnant with DS, I had just finished yoga teacher training and was eating super healthy. I had a super easy pregnancy with him. Not one second of morning sickness. I had no cravings or food aversions. It was a pretty amazing and easy pregnancy, aside from being persistently breech and requiring a c-section. So, trade-offs?
With DD, I wasn't exactly as super fit and eating as wholesomely as I was when I was pregnant with DS. Also, I was still nursing. I had serious chicken aversions while pregnant with her, but I did crave really good hamburgers. I also wanted sweets, and conversely spicy hot wings and salt and vinegar chips. And cherry icees.... Oddly... I gained less with DD than with DS! I also had mild to moderate morning sickness.
This time, I don't know the sex and we're waiting to find out but it has been the hardest pregnancy so far in terms of horrible and constant nausea. I have more food aversions, although I can now tolerate chicken - but only if its seriously minced up with a bunch of other stuff - and that's only been in the last couple weeks. I also want hamburgers again. And pretzels (but I think that is because I am trying to quell the nausea). I was not out of shape, but I wasn't eating as super healthy as I was when I got pregnant with DS, although I do cook at home almost every night. I was also still nursing (am still nursing) DD when I got pregnant.
My first child is a boy, and protein is the thing that most made me feel sick to my stomach.. So im not really sure how true that is.. though I do think that maybe just having more of an appetite in general may mean a baby boy..or at least that's an old wives tale ive heard. If that's so, then I must be pregnant with a GIRL right now because I have not had an appetite at all!
Kyamo, I have to agree with you. The man's contribution to the pregnancy determines whether it will be a boy or girl. Unless the theory is that a Y sperm somehow "knows" something about the nutrition of the particular egg it is fertilizing, the nutrition thing sounds weird to me.
I definitely want more salt this time around than last time and want to eat more junk. Last time (it was a boy), I wanted a lot of meat to eat; that was the thing that was most satisfying. I could see the mother's dietary cravings or possibly even needs being slightly different whether she is carrying a boy or a girl, but not necessarily that conception of either gender is related directly to diet...??
My understanding of those studies is that diet won't determine sex, but that a good diet will make boy babies more likely to "stick" - apparently boys need more and/or a greater variety of nutrients. I'm not a scientist so I don't if that is accurate or the studies are valid, but that is the way my nurse sil explained it to me. My mother, who had very unusual gynecological problems and suffered several miscarriages, knows at least three of them were boys and thinks the others were too. Throughout history you can seen patterns in documented families of stuggles to have male children - multiple pregnancies losses with only the female babies delivered to term. So I think it is possible. I don't know about the size thing. My boys were pretty big, and my sister's boys were big, but my sil's boy was tiny - he weighed half as much as my ds2! My one girlfriend with girls had smaller to average babies - I think they were in the 6lb range. I don't know anyone who has one or more of each so I can't compare.
I also craved protein during my prior pregnancies and had boys. I ate eggs everyday, and with ds2 I ate a lot of chicken liver and beef as well. I have been having a real aversion to eggs and most meat this pregnancy. Actually I don't have much of an appetite at all, so maybe that means a girl. We'll find out soon :)
I'm suprised to hear that there has been a decline in boys - we have all boys on both sides of our families, and we only have one set of friends with girls.
The sperm that carry Y chromosomes die faster than the X chromosome sperm. I suppose it's possible that a woman's diet could affect the pH of her vagina enough that it would kill off a higher number of male sperm and allow the female sperm to get to the egg.
It's generally believed that timing certainly influences gender....having intercourse closer to ovulation makes it more likely to create a boy because the male sperm are faster. Maybe people with better diets have more frequent sex, which leads to more boys.
the thinking is that you can change ph of the cervical fluid and the polarity if the egg, making it so that only one kind of sperm would have the best chance for surviving the fluid and then being attracted to the egg. <shrug>
father's age is a factor as well as frequency of sex=fresher sperm factor and ph levels----it is a combination
