This competition has become closed

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 evidence that is solid medical experts warn against using them too really. Some individuals say there’s strong anecdotal evidence and that there’s no harm in attempting them, as hardly any practices are intrusive.

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

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 when you have intercourse several days before ovulation then abstain (as the male sperm die), this will boost the likelihood of conceiving a woman.

Male semen are much lighter and swim faster than feminine people so can be more prone to achieve the egg. Consequently, making love regarding the time of ovulation should raise 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 sex across 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 significantly more than girls.

What’s the success price?
Advocates claim 7% but there’s only a small quantity of medical proof in britain to guide it.

Confusingly, another concept exists predicated on findings that partners that didn’t live together before conceiving had more girls. These were regarded as less inclined to have sexual intercourse at the right time of ovulation, backing within the indisputable fact that conceiving 4 or 5 times before ovulation ended up being more prone to make a kid.

Intimate place

What’s the idea?
Male semen are far more susceptible in addition to 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 therefore are more prone to endure the quick journey. Consequently, much much much deeper roles should suggest a child is much more most most most likely.

Shallow penetration should favour your odds of conceiving a lady – the slower feminine semen are hardy sufficient to withstand the conditions that are acidic the entry towards the vagina therefore might make it until the egg after the male semen have actually died off.

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

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

Male abstinence that is sexual

What’s the concept?
Abstaining for a couple of days before making love increases your odds of conceiving a kid. The more the amount of semen, the greater amount of sperm that is male show up, therefore theoretically there’s a larger possibility that the male sperm 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 probability of you conceiving a child could be greater, but there’s no sex element.

Changing your diet plan

What’s the idea?
The minerals in your daily diet could impact your metabolic process together with environment of one’s eggs.
– To improve conditions for male sperm you’ll need potassium (in meat, bananas, apricots and celery).
– To improve conditions for feminine semen you require more food that is magnesium-richin pea redtube.com pea nuts, soya beans and leafy greens).

What’s the success price?
There’s no clinical data on people to aid the potassium or magnesium theories, although specialists say diet does appear to play some component in sex selection.

Historic activities demonstrate that famine can lead to more males being created but also that ladies weighing lower than 4.kg are more inclined to have girls. This can imply that the kind of meals and nutritional elements offered to those individuals played a component, or that calories comes with an effect – but a diet that is low-calorie a extremely various impact to malnutrition.

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 much better environment for male semen. Female sperm survive better when you look at the obviously acid environment of the vagina, therefore climaxing first would favour the conception of men.

What’s the success price?
Minimal. Extended foreplay gets the exact exact same effectation of increasing genital secretions, that could be in the same way capable of reducing its acidity – but no body has recommended feminine foreplay as a way of conceiving men.

Douching

What’s the idea?
Male sperm favour alkaline conditions, so douching (flooding the vagina via a syringe) having an alkaline that is dilute, such as for instance salt bicarbonate (baking soda) before sexual intercourse escalates the likelihood of conceiving a child.

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