Sperm for Girls and Boys Yes. The X sperm (which are the sperm that make females) live longer than the Y sperm (which are the sperm that make males). However, the Y sperm swim faster, so the chances are equally good that you will get a girl or a boy. If the Y sperm swim fast enough before they die to fertilize the egg, then you'll have a boy. If the Y sperm don't reach the egg before they die, chances are an X sperm will get there shortly, and then you'll have a girl.
Here is more input and advice:
  • X sperm are stronger than Y sperm but both will perish very quickly if allowed to dry out.
  • The female carrying sperm are the slower sperm because of the genetic material it carries. The female sperm contain an X chromosome, while the male carrying sperm contain a Y chromosome. The Y chromosome is very small and contains very little genetic material in comparison to the X chromosome, so the male carrying sperm are able to swim faster and reach the egg sooner than the X carrying sperm.
  • A baby's gender is determined by the chromosomes in the sperm, not the egg. XX makes female, XY makes male, all eggs contain an X chromosome, so sperm donates other X or Y chromosome. Female sperm live up to 5 days, male sperm up to 3 days. (Egg lives 12 to 24, maybe even 36 hours after ovulation.) Female sperm live longer but swim slower than male sperm. (Vaginal environment supposedly contributes to sperm longevity, alkaline/acidic - male sperm prefer baking soda douche prior to sex, female prefer acidic (vinegar) (supposedly) - but most importantly of all, male swim quicker, so for male baby, have sex within 6 hours before ovulation, to beat female sperm to egg. Vice versa, for female baby, have sex 3-4 days before ovulation, for better chances of having a girl baby. Test for ovulation with home ovulation testing kit, get familiar with when you ovulate, and plan accordingly for future ovulations and future timing of intercourse.
  • Men produce two types of sperm, those containing the X chromosome, female sperm, and those containing the Y chromosome, male sperm. Sperm are being produced continuously, they take about a month from the beginning until they are mature. As the Y chromosome is smaller than the X chromosome the male sperm is lighter and faster than the female sperm and therefore gets a head start towards the egg. Female sperm being heavier have more staying power and can keep going for longer.



This is not really true

What your discussing is Dr. Landrum Shettles method and his research has been question by better scientist than him. He was trying to sell a book.

There's no dispute that the X chromosome is bigger than the Y chromosome, as this photo clearly shows. But the sex chromosome is only one of the 23 chromosomes carried by a sperm -- in total, an X sperm carries only 2.9% more genetic material than a Y sperm. As you can see, the difference isn't that great.

Total DNA in X Sperm
Total DNA in Y Sperm (2.9% less)
Data from the study shows that, not only are X and Y sperm indistinguishable from one another, even abnormal sperm cells with the wrong number of chromosomes -- too many or too few chromosomes -- cannot be identified by having a different shape or size.
