Old Fashioned Ways to Tell the Sex of a Baby

half dozen natural ways to choose your baby's sex activity – and their success rates

Shettles method, sexual position, timing - real or old wives' tales? We expect at the science behind the theories and how well they announced to work...

There are a lot of different theories and approaches to natural gender selection but very piffling scientific study. As in that location's no solid evidence, medical experts warn against taking them likewise seriously. Some people say there's strong anecdotal evidence and that in that location's no harm in trying them, as very few methods are intrusive.

Here'southward a round-up of the almost popular sexual activity selection methods around…

1 Timing of sex – Shettles theory & Billings Method

What's the theory?
Female person sperm are heavier and live longer than male sperm so if yous have sex activity a few days before ovulation and then abstain (while the male sperm die), this should increase the chances of conceiving a girl.

Male sperm are lighter in weight and swim faster than female ones and then are more likely to reach the egg. Therefore, having sex on the day of ovulation should increment the chances of conceiving a boy.

Dr Landrum Shettles developed this theory in the US in the 1960s. It'due south complemented by the Billings Method, which is most timing sexual activity effectually the consistency of vaginal fungus (when it's thin and clear for boys, thicker and stickier for girls). Information technology's said that couples using this method tend to have boys more than girls.

What's the success rate?
Advocates claim 75% simply in that location's only a tiny amount of medical evidence in the Great britain to support it.

Confusingly, another theory exists based on observations that couples that didn't live together before conceiving had more girls. They were idea to be less likely to have sex at the time of ovulation, backing upwardly the thought that conceiving four or 5 days earlier ovulation was more likely to produce a male child.

2 Sexual position

What's the theory?
Male sperm are more vulnerable and the vagina becomes less acidic closer to the cervix. And so if penetration is deep (woman-on-top or human being-behind positions), the male person sperm will enter a more than element of group i environment and are more probable to survive the short journey. Therefore, deeper positions should mean a boy is more likely.

Shallow penetration should favour your chances of conceiving a girl – the slower female sperm are hardy enough to withstand the acidic conditions at the entrance to the vagina so could make it through to the egg after the male sperm take died off.

What's the success rate?
Not high, since the theory fails to take into business relationship that the difference in lifespan between male person and female person sperm is a thing of days, non minutes.

Medical sceptics say that force of ejaculation and physics of sexual position don't play a part in getting the sperm to their destination more than quickly – that's determined by the chemical science of cervical mucus.

iii Male sexual abstinence

What's the theory?
Abstaining for a few days earlier making love increases your chances of conceiving a boy. The greater the book of sperm, the more than male sperm should exist present, so theoretically there's a greater hazard that a male sperm survives and fertilises the egg before a female person sperm can reach it.

What'south the success rate?
Not loftier. Sceptics say that with more than sperm, the chances of you lot getting pregnant may be higher, simply there'south no gender factor.

4 Irresolute your diet

What'due south the theory?
The minerals in your diet could affect your metabolism and the environment of your eggs.
– To improve conditions for male sperm you need potassium (in meat, bananas, apricots and celery).
– To ameliorate conditions for female person sperm yous need more than magnesium-rich food (in nuts, soya beans and leafy green vegetables).

What'southward the success rate?
There's no scientific data on humans to support the potassium or magnesium theories, although experts say diet does seem to play some part in gender selection.

Historical events have shown that famine can result in more boys being born merely also that women weighing less than 54.5kg are more likely to have girls. This could hateful that the type of food and nutrients available to those people played a role, or that calorie intake has an effect – just a low-calorie diet has a very different event to malnutrition.

5 Timing of orgasm

What'southward the theory?
If you achieve orgasm earlier your partner, your vagina becomes more element of group i, which creates a improve environs for male sperm. Female sperm survive better in the naturally acidic environs of your vagina, then climaxing get-go would favour the conception of boys.

What's the success charge per unit?
Little. Prolonged foreplay has the same upshot of increasing vaginal secretions, which could be just as effective at reducing its acidity – but no one has suggested female foreplay every bit a method for conceiving boys.

half-dozen Douching

What's the theory?
Male sperm favour alkaline conditions, so douching (flooding the vagina via a syringe) with a dilute element of group i solution, such every bit sodium bicarbonate (blistering soda) before intercourse increases the chances of conceiving a boy.

What's the success rate?
At that place's a very small amount of medical evidence that backs up this theory, but some experts warn women against putting sodium bicarbonate into their vagina because they may not know how diluted to make it, and in whatsoever case, the acid in the vagina is there for necessary protection against infections like thrush.
