Frequency and timing of intercourse:
shettles says in order to increase the
chances of having a girl, you should have
sex everyday from the end of your period
up to 2 1/2 to 3 days before ovulation.
After this point, do not have unprotected
sex until several days past ovulation.
Intercourse further away from ovulation
favors the larger slower moving x (girl)
sperm. The weaker y (boy) sperm will die
more quickly in the more acidic
preovulatory vaginal / cervical secretions
and by the time of ovulation there will be
a much larger concentration of x (girl)
sperm available to fertilize the egg.
Sexual position:
shettles suggests that if you are trying
to conceive a girl, shallow penetration
from your partner, preferably with the
missionary position, will deposit the
sperm closer to the entrance to the
vagina. This area is more acidic than
closer to the cervix and acidity will work
against the weaker "boy" sperm leaving
more "girl" sperm available to fertilize
your egg.
Sex and orgasms:
when trying to conceive a girl, shettles
recommends that you don't orgasm during
sex as the body produces substances after
orgasm that makes the vaginal environment
more alkaline, which favors the "boy"
sperm.
The contractions which accompany an orgasm
help move the sperm up and into the
cervix, giving the "boy" sperm an extra
chance at being available when your egg is
available for fertilization.
Take care
