Hi all. Hope someone can help. We are TTC a girl using shettles. I have just had the LH surge smily face on the clearblue wee sticks (yay!). Do I stop BDing now? Sorry to have to ask, I read the book and left in back home in the UK - we're overseas now.
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 so yes, stop having sex since ovulation will most likely occur about 24 hours after the time when you get a positive result for the lh surge on your ovulation predictor kit.. 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.
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.
When trying to conceive a girl, Shettles recommends that you dont 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.
