This competition happens to be closed

There are a great number of various theories and methods to normal sex selection but almost no study. As there’s no evidence that is solid doctors warn against using them too seriously. Some individuals 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 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 longer than male semen therefore when you yourself have intercourse several days before ovulation then abstain (as the male sperm die), this will boost the odds of conceiving a lady.

Male semen are light and swim faster than feminine people so might be prone to achieve the egg. Consequently, making love regarding the time of ovulation should raise the likelihood 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 can be about timing intercourse across the consistency of genital mucus (whenever it is thin and xnxx videos clear for males, thicker and stickier for women). It is said that partners that way are apt to have men a lot more than girls.

What’s the success rate?
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 predicated on findings that partners that did live together before n’t conceiving had more girls. These people were regarded as less likely to want to have sexual intercourse in the right time of ovulation, backing within the indisputable fact that conceiving four to five times before ovulation ended up being prone to make a kid.

Sexual place

What’s the idea?
Male semen tend to be more susceptible additionally 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 tend to be more prone to endure the journey that is short. Consequently, much much much deeper roles should suggest a child 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 towards the vagina therefore might make it until the egg after the male sperm have actually died down.

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

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

Male intimate abstinence

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 male semen should be there, therefore theoretically there’s a better opportunity that the male semen endures and fertilises the egg before a lady sperm can achieve it.

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

Changing your diet plan

What’s the idea?
The minerals in what you eat could impact your metabolic process plus the environment of one’s eggs.
– To improve conditions for male semen 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 pea nuts, soya beans and leafy greens).

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 may result in more males being created but also that ladies weighing significantly less than are more inclined to have girls. This can imply that the sort of meals and nutritional elements accessible to those individuals played a component, or that calories has an effect – but a low-calorie diet has a various impact to malnutrition.

Timing of orgasm

What’s the theory?
in the event that you reach orgasm before your spouse, your vagina becomes more alkaline, which produces a much 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?
Little. Extended foreplay has got the exact exact same effectation of increasing genital secretions, that could be in the same way able to reducing its acidity – but no body has recommended foreplay that is female a way for conceiving men.


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 example salt bicarbonate (baking soda) before sex advances the odds 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, plus in any instance, the acid within the vagina can there be for necessary security against infections like thrush.
