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

This competition has become closed

There are a great 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 too 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 most extremely popular intercourse selection techniques around…

1 Timing of sex – Shettles theory & Billings Method

What’s the theory?Female semen are heavier and reside much 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 much lighter and swim faster than feminine people so can be more prone to achieve the egg. Consequently, making love at the time of ovulation should boost the odds of conceiving a child.

Dr Landrum Shettles developed this concept in the usa when you look at the 1960s. It’s complemented by the Billings Method, which can be about timing intercourse across the persistence of vaginal mucus (whenever it is clear and thin for men, thicker and stickier for women). It is stated that partners that way are apt to have guys a lot more than girls.

What’s the success price? Advocates claim 75% but there’s only a small level of medical proof in britain to aid it.

Confusingly, another concept exists predicated on findings that partners that did live together before n’t conceiving had more girls. These were considered to be less likely to want to have sexual intercourse during the period of ovulation, backing up the proven fact that conceiving four to five times before ovulation ended up being more prone to create a child.

2 intimate place

What’s the idea? Male semen tend to be more susceptible together with vagina becomes less acidic nearer to the cervix. Therefore if penetration is deep (woman-on-top or man-behind jobs), the male semen will enter an even more alkaline environment and are usually very likely to endure the journey that is short. Consequently, much much much deeper jobs should suggest a child is much more most most most most likely.

Shallow penetration should favour your likelihood of conceiving a lady – the slow feminine semen are hardy sufficient to withstand the conditions that are acidic the entrance to your vagina therefore will make it through to the egg after a man semen have actually died down.

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

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

3 Male abstinence that is sexual

What’s the concept?Abstaining for the day or two before making love increases your chances of conceiving a child. The more the amount of semen, the greater amount of sperm that is male be there, therefore theoretically there’s a better possibility that the male semen endures and fertilises the egg before a lady semen can achieve it.

What’s the success price? Not high. Sceptics state by using more semen, the probability of you conceiving a child might be greater, but there’s no sex element.

4 Changing your daily diet

What’s the idea? The minerals in your daily diet could influence your k-calorie burning as well as the environment of the eggs. – To improve conditions for male semen you will need potassium (in meat, bananas, apricots and celery). – To improve conditions for feminine semen you require more food that is magnesium-richin pea pea pea pea nuts, soya beans and leafy vegetables).

What’s the bi sex chat success price? There’s no medical information on people to aid the potassium or magnesium theories, although specialists state diet does seem to play some component in sex selection.

Historic activities have indicated that famine can lead to more men being created but also that ladies weighing lower than 54.5kg are more inclined to have girls. This can imply that the kind of meals and nutritional elements accessible to the individuals played part, or that calories posseses an effect – but a diet that is low-calorie a various impact to malnutrition.

5 Timing of orgasm

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

What’s the success price? Minimal. Extended foreplay has got the exact same aftereffect of increasing genital secretions, which may be in the same way able to reducing its acidity – but no body has recommended foreplay that is female a way for conceiving guys.

6 Douching

What’s the idea? Male sperm favour alkaline conditions, therefore douching (flooding the vagina using a syringe) with a dilute alkaline solution, such as for instance salt bicarbonate (baking soda) before sex boosts the likelihood of conceiving a kid.

What’s the success price? There’s a tremendously tiny amount of medical proof that backs up this concept, many specialists warn females against placing salt bicarbonate within their vagina since they may well not understand how diluted making it, as well as in any instance, the acid when you look at the vagina will there be for necessary security against infections like thrush.
