Shettles technique, intimate position, timing – genuine or old wives’ tales? We consider the technology behind the theories and just how well they may actually work.

This competition happens to be closed

There is a large number of various theories and methods to normal sex selection but hardly any study that is scientific. As there’s no evidence that is solid doctors warn against using them as well really. Many people say there’s strong anecdotal evidence and that there’s no harm in attempting them, as not many techniques are intrusive.

Here’s a round-up of the very most sex that is popular techniques around…

Timing of sex – Shettles theory & Billings Method

What’s the idea?
Female semen are heavier and reside much much longer than male semen therefore then abstain (while the male sperm die), this should increase the chances of conceiving a girl if you have sex a few days before ovulation and.

Male semen are light and swim faster than feminine people so might be almost certainly going to achieve the egg. Consequently, sex in the time of ovulation should raise the odds of conceiving a kid.

Dr Landrum Shettles developed this concept in the usa into the 1960s. It’s complemented by the Billings Method, which can be about timing intercourse across the consistency of genital mucus (whenever it is thin and clear for males, thicker and stickier for females). It is stated that partners that way are apt to have males significantly more than girls.

What’s the success rate?
Advocates claim 7% but there’s only an amount that is tiny of proof in the united kingdom to guide it.

Confusingly, another concept exists according to findings that partners that didn’t live together before conceiving had more girls. These were considered to be less inclined to have sexual intercourse in the right period of ovulation, backing up the proven fact that conceiving 4 or 5 times before ovulation ended up being prone to create a kid.

Intimate place

What’s the idea?
Male semen are far more susceptible therefore the vagina becomes less acidic nearer to the cervix. Therefore if penetration is deep (woman-on-top or man-behind jobs), a man semen will enter an even more alkaline environment and generally are prone to endure the quick journey. Consequently, much deeper jobs should mean a child is much more most most likely.

Shallow penetration should favour your odds of conceiving a lady – the slower feminine semen are hardy sufficient to withstand the acid conditions at the entry to your vagina therefore might make it until the egg after a man semen have actually died down.

What’s the success price?
maybe perhaps maybe Not high, because the concept doesn’t remember that the real difference in lifespan between male and female semen is a matter of a few times, maybe perhaps maybe not moments.

Health sceptics say that force of ejaculation and physics of sexual position don’t play a role in getting the semen for their location more that’s quickly based on the chemistry of cervical mucus.

Male intimate abstinence

What’s the concept?
Abstaining for the day or two before making love increases your odds of conceiving a kid. The higher the amount of semen, the greater amount of male semen should show up, therefore theoretically there’s a better possibility that a male semen endures and fertilises the egg before a lady semen can achieve it.

What’s the success price?
Perhaps Not higher. Sceptics state that with more semen, the likelihood of you having a baby could be greater, but there’s no sex element.

Changing your diet plan

What’s the idea?
The minerals in what you eat could influence your kcalorie burning therefore the environment of one’s eggs.
– To improve conditions for male semen you will need potassium (in meat, bananas, apricots and celery).
– To improve conditions for feminine semen you may need more food that is magnesium-richin pea pea pea nuts, soya beans and leafy greens).

What’s the success price?
There’s no medical information on humans to guide the potassium or magnesium theories, although professionals state diet does appear to play some component in sex selection.

Historical activities demonstrate that famine may result in more males being created but also that ladies weighing not as much as are more inclined to have girls. This might imply that the sort of meals and nutritional elements offered to the individuals played a component, or that calories comes with an effect – however a diet that is low-calorie a really different impact to malnutrition.

Timing of orgasm

What’s the idea?
in the event that you reach orgasm before your spouse, your vagina becomes more alkaline, which produces a much better environment for male semen. Female sperm survive better into the naturally acid environment of one’s vagina, therefore climaxing first would favour the conception of guys.

What’s the success price?
Minimal. Extended foreplay gets the exact exact exact same effectation of increasing genital secretions, that could be just like able to reducing its acidity – but nobody has recommended feminine foreplay as a way of conceiving guys.


What’s the idea?
Male sperm favour alkaline conditions, therefore douching (flooding the vagina with a syringe) with an alkaline that is dilute, such as for example salt bicarbonate (baking soda) before sex advances the odds of conceiving a kid.

What’s the success price?
There’s a tremendously little bit of medical proof that backs up this concept, however some specialists warn females against placing salt bicarbonate within their vagina simply because they may well not understand how diluted making it, plus in any situation, the acid redtube. com within the vagina will there be for necessary security against infections like thrush.
