    Hi Ladies,

    As my thread name suggests i was just wandering if any of you had practised the shettles method, or do you know anybody that has and how did it work out?

    Since i found out about it, it has fascinated me!!!!

    Thanks in advance

    this is what i did for my college extended assignment. shettles claims his method can sway the 50-50 balance to 75-90% success rate in favour of a child of a desired gender.
    - i can tell you that not only do i know a handful of people who have done it and succeeded, but from the survey i did with 83 participants, those who did try it were looking to conceive girls.

    i can also tell you that in my assignment i put shettles theory to the test, and put it into a chi-square formula. basically its a statistical formula used to determine if chance (nature) is responsible or if there is anything to his method.

    my result, is that gender inheritance is not due to chance and there is something in his method. i can explain this in more detail if you like?

    this topic fascinates me!

    well basically, yes the ovum is randomly fertilised by x or y sperm. however, the timing of intercourse around or on ovulation determines inherited gender. (as we know - or are told)

    now according to the punnett square that is used to predict the outcome of a particular cross or breeding experiment, a child has a 50-50 chance of being male or female. this we know, however, as humans have so few children (unlike insects, animals etc) chance (nature) is never questioned.

    therefore, the chi square test is a statistical equation that determines if a result is down to chance or not. out of shettles case studies in the book, apparently not 'cherry picked', 46 couples were successful in gender selection and 6 were unsuccessful. placing this in the chi sqare gives us an answer of 25.14 (can show calculation if anyone interested).

    this score is then compared to the deviation figure of 3.84 (on a chi square results table) - the object is to find the deviation figure and if the results are smaller than the deviation figure then chance is the reigning factor, however if the end figure is larger than the deviation figure then it is not down to chance.

    the results of shettles case studies was 25.14 - a larger number than 3.84 - shettles theory is not due to chance.

    so my sceptical husband and i put it to a 'real test'...between 83 survey participants, they have a total of 129 children. of those 52 are girls and 77 boys. technically the girl boy ratio should be 50% therefore 64.5 - which is half of 129 (or near enough), but as its not, the figures are placed in a chi-square test.

    the result was that we ended up with an answer of 4.844 - which is still larger than the deviation figure of 3.84 meaning that there is something more than just chance.

    however, just because the figures say that gender is not due to chance alone it doesnt mean that everyone is choosing their childs gender. BUT, looking back at when my boys were conceived - i knew nothing about the method at the time, but dh and i realise we never had a chance of conceiving a girl.....

    my very sceptical hubby and complete figure freak is now a believer...purely down to that test! does this make sense?

    when I was pregnant I read a book by dr robert winston about fertility, from his theory I predicted I would have a girl. I presume its a similar theory 'time of conception influences the baby being either a boy or girl?
