Tips to have a baby boy

Determining the Time of Ovulation: Determining when you ovulate is vital when you are learning how to conceive a boy. Shettles recommends that you have sex as early as 24 hours before ovulation to no more than 12 hours past ovulation in order to increase your chances of conceiving a boy. Having sex too far in advance to ovulation will dramatically decrease your chances of conceiving a boy. The timing of intercourse in relation to ovulation is a vital factor in increasing your chances of having a boy.

Frequency and Timing of Intercourse: Shettles says in order to increase the chances of having a boy, you should have sex no earlier than 24 hours before ovulation to 12 hours after ovulation.Intercourse closer to ovulation the faster but less robust Y (boy) sperm. The cervical mucus present at ovulation is less acidic and "slippery" enough to help the Y (boy) sperm reach the egg more quickly.

Sexual Position: Shettles suggests that if you are trying to conceive a boy, deep penetration from your partner, preferably with the "doggy style" position, will deposit the sperm closer to the cervix giving the more aggressive and quicker moving "boy" sperm a head start to fertilizating the egg first.

Sex and Orgasms: When trying to conceive a boy, Shettles suggests that orgasms during sex are a good thing 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.

Considerations for the Men: Have your partner wear boxers. Wearing tight fitting underwear increases the heat levels around the testes and can, in turn, lower the sperm count. Wearing loose fitting underwear helps keep the testes cooler.Have your partner drink a caffeinated beverage right before sex. This makes the Y-Sperm more active.

Tips to have a baby girl

Determining the Time of Ovulation: Determining when you ovulate is vital when you are learning how to conceive a girl. Shettles recommends that you have sex 2 1/2 to 3 days BEFORE ovulation in order to increase your chances of conceiving a girl. Having sex closer to ovulation will dramatically decrease your chances of conceiving a girl. The timing of intercourse in relation to ovulation is a vital factor in increasing your chances of having a girl.

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.
