Dear premier,

What if first child be a boy then will there be only boys. I don't know where you have gathered such information,.
Eventhough certain studies suggest the certain couples with certain blood groups have a chance to have more male babies than the other groups burn it doesn't mean reverse. And as a fact blood groups is not determining factor for sex of the child .it's exclusively the genes . You have 50 percent chance for gettin a boy or girl in each pregnancy irrespective of the number if pregnancy or blood group . Rest is just by luck or by god .may both favour you .
Thank you

Hi,
Thanks for choosing HCM,

its false dear

sex of a baby is not related to the blood groups

it depends on sex chromosomes xx in female and xy in male
egg or ovum in mother has x chromosomes
sperm in father either has x or a y chromosome

if sperm with x chromosome fertilises the egg ,result is xx meaning a female child
if sperm with y chromosome fertilises the egg ,result is xy meaning a male child

so its the kind of sperm that is going to fertilise your egg that decides the sex

for sure same blood group of couple has nothing to do with the determination of sex of the baby
so keep your fingers crossed and wait for your baby
hope your queries are answered
wish you good luck
feel free to contact me for further queries
thank you
