Dr Landrum Shettles a renowned expert on baby gender prediction developed a simple, three step, at home, all natural baby gender selection method, that he felt was “best supported by scientific evidence”.

He wrote a million copy best selling book explaining his methods called How To Choose The Sex Of Your Baby which you will find a link to by visiting my website below. Dr Shettles claims a 75%-90% success rate using his simple, all natural, at home methods, and many thousands of couples have enjoyed an even higher (up to 98%) success rate using these very same methods to help them choose to have the baby boy or girl they wanted.

The Shettles method is based on the fact that it’s the man’s sperm that determines whether a baby is a female or male. This is because the woman’s egg carries only the (x) or (girl) chromosome, and the man’s sperm comes in two varieties, one carrying the (x) or girl sperm (which results in a girl baby) and the (y) or boy sperm (that results in a boy baby.) Dr Shettles also realized that the girl sperm was physically larger, stronger (longer lived), and a slower swimmer (slower to reach the egg.) The boy sperm is smaller, more fragile (dies off quicker), and is a much faster swimmer (will win the race to fertilize the egg most of the time.)

Dr Shettles realized that the timing of conceptual intercourse had a profound effect on the sex of the resulting baby. The depth of penetration during conceptual intercourse also plays a role in the gender of the resulting baby. The mother-to-be will have to learn how to track her day of ovulation as precisely as possible as this too plays a role.

If a boy baby is desired abstain from sex until the day before ovulation, and abstain again the second day after ovulation. Also when trying to conceive a boy sexual positions that allow deep penetration are best (“doggie style” or missionary position with the woman’s legs extended up towards her head.) Why is this? Because of the differences in the two sperm. This timing, and deep penetration allows the fast swimming boy sperm to win the race to the fresh waiting egg, resulting in the boy baby you want.

If you want a baby girl, you should only allow shallow penetration when having sex to conceive. Abstain from sex for a couple of days before ovulation until a couple of days after. Again, this will ensure the weaker boy sperm cannot survive the time and distance needed to successfully fertilize the egg, resulting in the girl baby you desire.

Shettles also realized that the mother-to-be’s bodily ph also plays a role in baby gender prediction. A lower ph (higher acidity) favors the girl sperm, while a higher ph (more on the alkaline side) favors the boy sperm.

Don’t leave anything to chance (if you are serious about choosing the gender of your baby.) You’ll need a guide to take you through the entire process step by step. You’ll find these guides at my website, so pick one up and raise your chance of success from a mere 50/50 to well over 90%!
