There is a large 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 taking them as well really. Many people say there’s strong anecdotal evidence and that there’s no harm in attempting them, as hardly any techniques are intrusive.

Here’s a round-up of the very most popular intercourse selection techniques around…

Timing of sex – Shettles theory & Billings Method

What’s the theory?
Female semen are heavier and reside much much longer than male semen 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 woman.

Male sperm are much lighter and swim faster than feminine people so might be more prone to achieve the egg. Consequently, making love at the time of ovulation should boost the odds of conceiving a kid.

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

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

Confusingly, another theory exists predicated on findings that partners that did live together before n’t conceiving had more girls. These people were considered to be less inclined to have intercourse during the right time of ovulation, backing within the indisputable fact that conceiving four to five times before ovulation ended up being prone to create a child.

Intimate place

What’s the idea?
Male semen are far more susceptible and also the vagina becomes less acidic nearer to the cervix. Therefore if penetration is deep (woman-on-top or man-behind roles), a man semen will enter a far more alkaline environment and are usually very likely to endure the brief journey. Consequently, much deeper roles should suggest a kid is more most likely.

Shallow penetration should favour your odds of conceiving a lady – the slow feminine semen are hardy adequate to withstand the conditions that are acidic the entry to your vagina so might make it until the egg after a man semen have actually died down.

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

Health 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.

Male intimate abstinence

What’s the idea?
Abstaining for a couple of days 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 larger opportunity that a male semen endures and fertilises the egg before a lady semen can achieve it.

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

Changing your diet plan

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

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

Historic occasions have indicated that famine can lead to more guys 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 those individuals played a component, or that calories posseses an effect – but a diet that is low-calorie a various 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 significantly better 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 males.

What’s the success price?
Minimal. Extended foreplay has got the exact exact exact same aftereffect of increasing genital secretions, which may be in the same way with the capacity of reducing its acidity – but nobody has recommended female foreplay as a way of conceiving guys.


What’s the theory?
Male sperm favour alkaline conditions, therefore douching (flooding the vagina using a syringe) by having an alkaline that is dilute, such as for instance salt bicarbonate (baking soda) before sexual intercourse advances the odds of conceiving a child.

What’s the success price?
There’s a rather tiny amount of medical proof that backs up this theory, however some professionals warn ladies against placing sodium bicarbonate within their vagina since they may well not understand how diluted making it, as well as in any instance, the acid within the vagina will there be for necessary security against infections like thrush.
