There is a large number of various theories and methods to natural sex selection but little study. As there’s no evidence that is solid doctors warn against using them as well 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…

Timing of sex – Shettles theory & Billings Method

What’s the idea?
Female semen are heavier and reside much much much longer than male sperm so 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 raise the likelihood of conceiving a child.

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

Confusingly, another concept exists according to findings that partners that did live together before n’t conceiving had more girls. These were regarded as less inclined to have sexual intercourse in the time of ovulation, backing within the proven fact that conceiving 4 or 5 times before ovulation ended up being prone to produce a child.

Intimate place

What’s the idea?
Male semen are far 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 generally are almost certainly going to endure the quick journey. Consequently, deeper roles should suggest a kid is much more most most likely.

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

What’s the success price?
maybe maybe maybe 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 days, maybe maybe maybe not moments.

Medical sceptics say that force of ejaculation and physics of sexual place 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 idea?
Abstaining for the days that are few making love increases your chances of conceiving a kid. The more the quantity of sperm, the greater amount of male sperm should be there, therefore theoretically there’s a better opportunity 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 probability of you conceiving a child can be greater, but there’s no sex factor.

Changing your daily diet

What’s the idea?
The minerals in your daily diet could influence your kcalorie burning while 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 nuts, soya beans and leafy vegetables).

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

Historic occasions have indicated that famine can lead to more males being created but also that ladies weighing not as much as 4.kg are more inclined to have girls. This can imply that the kind of food and nutritional elements open to the individuals played part, or that calories comes with an effect – however a low-calorie diet has a completely 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 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 same effectation of increasing genital secretions, which may be just like good at reducing its acidity – but nobody has recommended feminine foreplay as a way of conceiving guys.

Douching

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

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