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

This competition has become closed

There are a great number of various theories and ways to normal sex selection but almost no study that is scientific. As there’s no solid proof, doctors warn against using them too really. Some individuals 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 sex that is popular techniques around…

1 Timing of sex – Shettles theory & Billings Method

What’s the theory?Female sperm are heavier and reside much much longer than male sperm therefore when you yourself have intercourse a couple of days before ovulation after which abstain (whilst the male sperm die), this would raise the likelihood of conceiving a lady.

Male semen are much lighter and swim faster than feminine people so might be prone to reach the egg. Consequently, making love at the time of ovulation should boost the likelihood of conceiving a child.

Dr Landrum Shettles developed this concept in the usa within the 1960s. It’s complemented by the Billings Method, which will be about timing intercourse all over persistence of genital mucus (whenever it is thin and clear for men, thicker and stickier for females). 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 according to findings that partners that didn’t live together before conceiving had more girls. These were regarded as less likely to want to have intercourse during the right period of ovulation, backing within the indisputable fact that conceiving 4 or 5 times before ovulation had been more prone to create a kid.

2 intimate place

What’s the idea? Male semen tend to be more susceptible plus 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 are also almost certainly going to endure the brief journey. Consequently, much much deeper roles should suggest a child is more most most most most likely.

Shallow penetration should favour your odds of conceiving a girl – the slow feminine semen are hardy adequate to withstand the conditions that are acidic the entry into the vagina therefore will make it until the egg after the male semen have actually died down.

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

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

3 Male intimate abstinence

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

What’s the success price? perhaps Not higher. Sceptics state by using more semen, the likelihood of you conceiving a child are 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 metabolic rate therefore the environment of the eggs. – To improve conditions for male sperm you’ll need potassium (in meat, bananas, apricots and celery). – To improve conditions for feminine semen you may need more magnesium-rich food (in pea nuts, soya beans and leafy vegetables).

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

Historic occasions demonstrate that famine may result in more men being created but also that ladies weighing lower than 54.5kg are more inclined to have girls. This can imply that the sort of meals and nutritional elements accessible to the individuals played a component, or that calories posseses an effect – however a low-calorie diet has 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 an improved environment for male semen. Female sperm survive better into the environment that is naturally acidic of vagina, therefore climaxing first would favour the conception of guys.

What’s the success price? Minimal. Extended foreplay has got the exact exact exact 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 men.

6 Douching

What’s the theory? Male sperm favour alkaline conditions, therefore douching (flooding the vagina via a syringe) by having a dilute alkaline solution, such as for instance salt bicarbonate (baking soda) before sexual intercourse boosts the odds of conceiving a kid.

What’s the success price? There’s a really little bit of medical proof that backs up this concept, many specialists warn ladies against placing salt bicarbonate within their vagina simply because they might not understand how diluted making it, as well as in any instance, the acid into the vagina will there be for necessary protection against infections like thrush.
