Baby gender vs. Blood renewal

[crystaldrops]

Yea by this calculation, my sis and I should both be boys. Im gonna agree that these are all just wives tales. They are fun to look at tho! I should have a girl if we conceive by my birthday!
I have heard theories about certain woman not being able to carry boys or girls because their immune systems just do not accept them. Their body actually rejects the sperm of embryos of that specific sex. Not sure if that is a proven medical theory....

i'm sure it is nit proven but interesting too!

the only thing i can say that proves all these gender selection things wrong is... how do you explain boy/girl twins then.......

good point!!
