Girl/Boy, Boy/Girl

Whilst I’m sure a lot of couples would be happy just to have a baby of any size shape or variety, I also think that there are a lot who do have a preference over boy/girl some even try ‘swaying’ towards a particular sex. Maybe they’ve had 3 boys already and would love a daughter – maybe they want 2 of the same sex so they can form a great friendship. Whatever the reason there are various methods which claim to be successful in gender swaying.

Shettle’s Method.

Dr. Landrum Shettles first published his theories on pre-conceptual sex selection in 1970. They are based on the assumed differences between the X (girl) and Y (boy) sperm. The ‘boy’ sperm are supposed to be faster but more fragile (man flu excuses already?) than ‘girl’ sperm, which are thought to be slower but more resilient and have more ‘staying power’ (girl power!).

Bearing this in mind, the Shettles suggests that the timing of sexual intercourse during her cycle is the most crucial element for conceiving a baby of the desired sex. For boys, the method advocates timing sex to be as close to ovulation (or the woman’s egg release) as possible, but abstaining from sex for several days before this point in time, meaning that the faster ‘boy’ sperm will get to the egg first. For girls, the method recommends timing sex for the 2 to 4 days before ovulation, then abstaining from 1 to 2 days before ovulation until a few days after ovulation, giving the ‘girl’ sperm chance to sit in wait for the egg as the weaker ‘boy’ sperm will no longer be in contention.  The Shettles method claims an 80% success rate for boys and a 75% success rate for girls.

There is no guarantee of success of course as it can be very difficult to calculate your cycle  exactly, as they can alter slightly month to month. However as this method has no financial outlay it might be worth a shot!!


The idea that changing a woman’s diet for several weeks before she conceives to influence gender, originated from German studies in the 1940’s looking at the environment that influenced the reproduction of worms (ugh). In 1980 a research study was published aimed at testing this theory on determining the sex of babies in humans. It was thought that through diet, the mineral (or ‘ionic’) imbalance in the woman’s body could help gender selection. The ionic balance was thought to affect the chemical make-up of her egg and/or her vaginal secretions. You are in effect trying to alter your bodies Ph levels. A high Ph means your body is more alkali which supposedly favours boys where as an acidic Ph supposedly favours girls!

The boy diet can include – bacon, ham, sausages (and other salty meats), meat, fish (especially if dried and salted), salted chips and nuts, rice, pasta, potatoes, most fresh vegetables, bananas, apricots and most fresh fruits, white bread, pastries, fruit loaf, honey, jam, soups and carbonated drinks.

The girl diet can include – dairy products, yoghurt, ice cream, eggs, mineral waters, fresh fruit juice, rice, pasta, salt-free bread and butter, no salt in foods and only small amounts of fish, meats and fresh vegetables and fruits.

However the diet does contradict everything else we are told as it may not be balanced enough to provide much needed vitamins and minerals for a healthy conception and pregnancy. The boy diet seems to be high in salt, and the girl diet high in dairy, we are always recommended to eat healthy balanced diets and these are a little extreme. I would simply not be able to follow this as I love food too much, and the ‘girl diet’ would be a big no no for me as a life without bacon or intact just generally salty food is unthinkable 😉 .

After having 1 of each I have no shame in admitting I always wanted boys – I was a tomboy I played with Star Wars figures and Castle Grayskull, I skateboarded and climbed trees all the princess stuff was pretty alien to me. It doesn’t mean I love my daughter less than my son in any way.

Would you/did you try to sway? Did it work?
