Let’s flash back to grade school/jr high/high school/whenever you got Sex Ed for a moment… There is this thing called the Egg. It is introduced to a thing called a Sperm. The egg is an X, the Sperm is either an X or a Y. Two Xs and the resulting baby is a Girl, an X and a Y and the baby is a boy.
It is a bit more complicated (see below) but for most intents and purposes the biological sex of the fetus happens at the biological level (hormones, etc).
Not at the social/ locational/ dietary/ environmental levels such as what Mom is eating for breakfast.
Funnyily enough while looking up the technical terms for the (see below) educational aspect of this rant I came across another example of stupidity.
From the site childbirth.org (where "birth is a natural process not a medical procedure") I found this internet quiz that you could take that would tell you the gender of your unborn baby. An online test mind you... not any of the medically relevant sort of things... you know, with doctors or trained professions....
There were a whole bunch of questions regarding urine color, shape of tummy, sleeping patterns... and then these darling questions that made me want to band my head against something wooden and scream.
The Dad-to-be is
gaining weight right along with me.
is not gaining weight.
My mother's hair color is
not gray (natural or dyed).
My age at the time of conception was:
Conception took place in the month of....
Hang a thread with a needle over your belly. The thread moves
from side to side.
If someone asks you to show them your hands, you:
Show them palm up.
Show them palm down.
How do you pick up a mug?
Body of the mug.
Now wait... before you just assume that these questions have NOTHING to do with ANYTHING, here is the explanations:
Dad-to-be hasn't been gaining weight along with Mom-to-be, so it will be a girl.The maternal grandmother doesn't have gray hair (dyed or natural), so a girl will be born.Since the sum of the mother's age at conception and the number of the month of conception is an odd number, it will be a girl.A needle on a thread held over you belly moves from side-to-side, so it will be a girl.You show them the palm of your hand, so it's a girl.You use the handle, so it's a boy.
The site also had advice on fertility and feeding the baby but I didn’t want to vomit on my keyboard….
Things like this make me seriously doubt my future ability to write fiction... because I can't make crap like this up. (Some lame thread of rational thought that my parents had implanted or something -Thanks Mom!)
I know I know I know that having babies is a great wonderful natural thing... (even if it is sort of kind of like a medical procedure.... sometimes) but there are times when I think there ought to be some sort of a test beforehand. (Heck, you need a license to drive, to fish, to hunt to get married.... ) I kid (mostly) but sometimes I really wonder about people.
Ok time to take a breath, eat some soup, try to ignore the pounding Harvey Danger song in the back of my mind*, and get back to work.

At 4 weeks of age the fetus undergoes the Development of wolffian ducts
In both the male and the female the Wolffian duct develops in to the trigone of urinary bladder, a part of the bladder wall. However, further development differentiates between the sexes in the development of the urinary and reproductive organs.
In a male, it develops into a system of connected organs between the testis and the prostate, namely the rete testis, the efferent ducts, the epididymis, the vas deferens,and the seminal vesicle. The prostate forms from the urogenital sinus.
For this it is critical that the ducts are exposed to testosterone during embryogenesis. Testosterone binds to and activates androgen receptor, affecting intracellular signals and modifying the expression of numerous genes.
In the mature male, the function of this system is to store and mature sperm, and provide accessory semen fluid.
In the female, in the absence of testosterone support, the Wolffian ducts regresses, and inclusions may persist. The epoophoron and Skene's glands may be present. Also, lateral to the wall of the vagina a Gartner's duct or cyst could develop as a remnant.
