But its still the egg that decides which sperm gets in isnt it?!? Or is a sperm both x and y ?!? Can you tell i didnt study Biology that hard at school?!?
The sperm are either x or y chromosome. It is believed that the x-chromosome sperm can swim quicker but do not live as long which provided the theory behind Shettles method that you can try and help predict the sex of your baby by having sex at certain times after the woman produces her egg. The theory saying that if you have sex quickly after the egg has just been produced then the x-chromosomes whilst outrunning the y-chromosomes will all have died before reaching the egg meaning there is more chance of your baby being male, if you wait until after the egg has virtually completed its journey then the x-chromosomes will reach it much quicker than the y-chromosomes and still be alive meaning more chance of a female baby. Unfortunately the egg doesnt really choose which sperm gets to be the lucky one and none of them are wearing "x" & "y" t-shirts to indicate which chromosome they are carrying. It isnt until several weeks after the foetus is developing before it can be determined which chromosome was being carried and therefore the sex of your baby. You've had enough of them - surely you know how it works by now!!  |

You've had enough of them - surely you know how it works by now!! Thank you So stretching it, I AM right! It is the female that decides what sex the baby will be, even if the egg does not know which sperm it is letting in Like if you have $100 in one hand and nothing in the other and I get to choose - it is MY choice that decides if I pick the $100 , not yours. True?? |

Women rule the world basically. They control everything.
Washing, ironing, cooking... the list is endless.

True??
But the egg doesnt get to "choose" which sperm fertilizes it. Fertilization occurs when one of the sperm penetrates the wall of the egg - neither the sperm nor the egg decide, so technically it is neither. |

Interestingly.....the only people who are afraid of losing their hair tend to be people with hair.
The only people who are bothered if you are fat are thin people
The only people who are bothered if you smoke are non smokers
so I would like to say to all the miserable people out there....GET HAPPY!!!!!!!
Thank you for letting me get that off my chest

Is it possible for someone who has no hair to be afraid of losing their hair?  |
