The Shettles Method is a gender selection method that was discovered in 1960 by a biologist called Dr Landrum Shettles. He later wrote a book called "How To choose the sex of your baby" where he published his finding.
A lot of couples would like to balance their family by a particular gender. Either Boy or Girl.
But the problem is the cost of IVF or other types of artificial sex selection is way too expensive.
You can plan your baby if you understand and follow the Shettles theory.
How Does the Shettles theory Work?
A baby's gender is determined the moment the sperm meets the egg during conception.
Dr Landrum Shettles discovered that the sperm of a man consist of two types of chromosomes (XY). While the egg of a woman has only one type of chromosome(X).
If the sperm with the X chromosome reaches the egg first a baby girl is conceived. But if the sperm with the Y chromosome reaches the egg first a baby boy is conceived.
The most interesting part of his discovery was the fact that he also discovered that this two types of sperm look, act and behave differently.
Here is what he discovered:
- The Y carrying chromosome sperm(boy sperm) is smaller and therefore swims faster but weaker.
- The X carrying chromosome sperm(girl sperm) is bigger and therefore swims slower. But is also strong and can withstand the acidic conditions of the vagina.
With this knowledge, you can take advantage weakness, strength and speed of the sperm to determine the sex of your baby.
So here is what Dr Landrum suggested If you want to have a boy:
Shettles for a Boy
To get pregnant with a boy, Shettles suggested that timing intercourse as close to ovulation is key and a deep penetration sexual position should be used.
1. Timing Intercourse
Shettles suggested that you make love on the day you ovulate or a day after ovulation to conceive a boy.
The logic and the technique behind this is based on the fact that the Male sperm swims faster and dies quicker while the female sperm swims slower and lives longer.
So by having sex the day the egg is released from the ovary(ovulation), the fast swimming boy sperm will be able to reach the egg first to fertilise it. There by increasing the chances of having a boy.
If you have sex too early before ovulation, the boy sperm(y) would be dead before the egg is released, thereby increasing the chances of the x sperm fertilising the egg.
Moreover, the slippery egg white cervical mucus produced at ovulation is alkaline which favours the conception of a male child.
2. Sexual Positions for a boy
He also suggested that to increase your chances of having a boy, the sperm should be released or placed as close to the cervix as possible.
The reason for this, is to help the Boy sperm escape the harsh environment in the vagina because of their weak nature.
A position that provides an opportunity for deeper penetration such as the doggy style should be used. And the father should deliberately make sure he ejaculates very deeply as close to the cervix as possible.
3. The Woman should have an orgasm first
He also advised for couples trying for a boy, the woman should have an orgasm first before the woman.
Because when a woman has an orgasm she produces more slippery cervical mucus which increase the Ph of the vagina.
Making the vagina more favourable and friendly place for the Y sperm to survive.
4. The man should abstain From ejaculation or sex 3-4 days before ovulation
Oh yes, you read that right. The Dad to be should avoid ejaculation at least 3-4 days before ovulation.
This would help increase or boost the concentration of the sperm count. Resulting in more stronger and matured boy sperm swimming to meet the egg.
Low sperm count favours the conception of a girl.
If you abstain for too long, say over 4 or 5 days or frequent release before ovulation would favour a girl.
For a boy, you can ejaculate and then abstain for 3-4 days before baby dancing at ovulation. This would ensure new and stronger sperm has been formed.
More Ways To Increase Your Chances of Conceiving a Male Child
5. Eat Alkaline Rich Foods or Diet
An alkaline CM favours boys. while an acidic CM favours girls.
The normal Ph of the vaginal is 4-4.5 which is slightly acidic in nature.
To boost your chances a vaginal PH of 7-9 is recommended to have a male child. So, it is recommended you start consuming alkaline rich foods months before ovulation or baby dancing(sex) to have a boy.
Eat Foods high in Potassium but low in calcium and magnesium
Foods such as baked potatoes with skin, leafy green vegetables, drink apple cider vinegar with water or lemon and water in the morning.
Shettles to get a Girl
The concept for conceiving a girl is the opposite for shettles strategy for a boy.
Dr Landrum suggests you do the following:
1. Have Sex 2.5 days to 3 days before Ovulation
The farther you have sex from ovulation the more you increase your chances for having a girl.
The sperm can survive up to 3 days (72 hours) in a woman. But the Y sperm because of their weak nature dies off faster than this.
Using this strategy, will help ensure that the X sperm who live longer have a greater chances of being alive to meet the egg by the time it is released 72 hours later.
This means you need to be able to pinpoint ovulation accurately. I normally suggest women have atleast 3 months of practise to pinpoint their ovulation.
It is very important to be able to do so. Having of sex 2.5-3 days is very key if using the shettles technique.
2. Sexual Positions for a girl
He suggested, you make use of a shallow penetration position like the missionary style when trying for a female child. The sperm should be ejaculated as far away from the cervix as possible.
This will ensure that the female sperm have a greater chance of surviving and thriving in the vagina. This is due to their strength and surviving skills.
While the weak male sperm struggle and find it difficult navigating their way upwards to meet the egg.
The missionary position is the most recommended position for conceiving a girl.
3. Woman Should Avoid Orgasm
According to Shettles, women should avoid having an orgasm if they want a baby girl.
This is because having an orgasm makes the vagina more alkaline and the male sperm would have the advantage of thriving and swimming fast up.
The X sperm thrives in the acidic vagina so you want to preserve this to boost their chances.
4. Girl Diet
Eat foods rich in calcium and magnesium and stay away from potassium rich foods.
To sway for a girl:
1. Drink 3 cups of milk everyday
2. Eat boiled egg
3. Eat acidifying foods like yogurt, grapefruit, oranges, corn.
4. Skip breakfast to reduce blood sugar level
Shettles Success Rate
What is the success rate of this method by Dr Landrum?
The method claims to have a 80%-85% success rate for a boy and 75%-80% success rate for a girl.
