Is there any truth to this?

My husband told me that he heard that the girl sperm can swim a longer distance than the male sperm and that depending on what day of the month we have intercourse it could give us more a chance to have a girl. Is this true or is it an old wives tale?

  • It is true but his sperm will determine the sex not the time of the month so that is a old wives tale.

  • You can increase your chances of having a boy or a girl by choosing the right time for intercourse. Sperm carrying X-chromosomes lives longer and swims slower than male Y-carrying sperm. Therefore, if you have intercourse about 3 days prior to ovulation, you have a better chance of conceiving a girl; and the closer to ovulation you have sex, the better the chances are of having a boy

  • The x chromosome is bigger, therefore, sperm carrying it are slightly heavier. I don't know if they actually live longer. So if all things are equal, the sperm carrying female chromosome will be a little slower, giving the boys the first round at the egg, but also the first opportunity to empty out of the tubes, leaving the females behind. However, I don't believe that all sperm are created equal in terms of speed, so it's not a guarantee or anything.

    I do know that some fertility clinics that do family balancing will centrifuge the sperm-- at certain speeds, the female sperm will collect at the bottom, leaving the male sperm floating in the suspension. They will then inseminate you with one or the other-- depending on what you want. The probability of success is greater in these instances, but still, not 100%.

  • No. The Shettle's method has been disproven over, and over and over. Shettle's was the only person to show successful numbers based on his theories.

  • IF you want to have a girl.... You have to have sex a day or two before you ovulate. Girl spermies swim longer and further.. So the boy spermies will die off before the girl, so when you finally drop an egg, the girl spermie is there
