Gender Selection

Gender or Sex Selection is a programme designed to influence the gender of your child combining the theories and techniques of 3 different approaches for maximum advantage. However, there are obviously no guarantees, although many of the authors of these theories claim very high success rates of 70-80%.

Sex Selection can be seen as meddling with nature and also as an indulgence, although, in practice, most people who make the effort to achieve a particular gender for their children do so for quite serious reasons. These may include the desire to avoid passing on a sex-related inherited disease, or to redress the imbalance in a family already oversupplied with one sex. There are, however, those who seek to influence the sex of their children for sexist reasons or because of the demands of a sexist society.

Therefore, Claudette only offers the Gender Selection programme to couples who have no history of fertility problems, who already have two children of the same sex and who are obviously wanting to have another child regardless of the gender as there are no guarantees to the programme.

Even without our interference, there are some surprising trends in nature’s allocation of boys and girls.

More girls tend to be born to:

  • Older parents
  • Parents with more children
  • Parent who take Clomiphene (a fertility drug, commonly known Clomid or Serophene)
  • Parents who conceive after some disasters, eg flood, smog and hepatitis outbreaks
  • Black Africans
  • Anaesthetists
  • American fighter pilots

Boys, however, predominate with:

  • Parents conceiving shortly after wars
  • Parents in the first 18 months of marriage
  • Parents having their first child
  • Parents giving birth at certain times of the year (often 9 months after a national holiday, a cold snap, or an energy blackout)
  • Parents who have more of the trace elements selenium and arsenic in their bodies
  • Caucasians
  • Jews

Is sex selection ethical?
Sex selection can offer the chance for more balanced, smaller families and more children feeling wanted. A girl who knows that her parents would prefer her to be a boy, or vice versa, has an unnecessary burden in life. If parents could choose their children with more success, there would be more love, less rejection and a reduction in family size. The pros and cons of sex selection were debated in a collection of essays in a book called Sex Selection for Children. This is a summary of some of the points raised.


  • Better population control
  • Better family planning
  • Happier families
  • Fewer unwanted children
  • Women’s status improved by being ‘chosen’
  • Avoidance of sex-linked diseases
  • Balanced two-child families


  • Preference for boys (historically)
  • Sex selection might only be available to certain groups (rich, educated)
  • Concentration of first- and second-born traits
  • Precedent for genetic engineering
  • Possible political abuse

Who’s responsible?
The debate through the ages about who is responsible…the man or the woman? According to Dr Shettles, a pioneer in the field of sex selection, it turns out fortunately to be both.

Dr Shettles, of Columbia Universities College of Physicians and Surgeons, a specialist in the field of reproductive physiology asserts that there are two types of sperm. The Androsperm is smaller, round-headed and contains the male-producing ‘Y’ chromosome. The Gynosperm is larger, oval-headed type carries the female-producing ‘X’ chromosome. The androsperm outnumber the gynosperm and are faster and more agile in favourable conditions but the female sperm shows greater survival capacity, being able to live longer and endure a more hostile or acidic environment in the vagina.

Although the “male” sperm start out with a considerable advantage in numbers, they end up only slightly ahead and live only 24 hours, whereas the ‘female’ sperm can survive up to 3 days. It’s a case of speed versus endurance.

So, according to Dr Shettles, the male contributes two types of sperm and the female supplies the environment which favours one or the other. As he says, a large single sex family could be the result of a highly acidic mother or a father who produces only or mainly androsperm. We cannot change the type of sperm that the father produces but we can change the environment of the mother.

What’s Involved.

The program involves monthly consultations for approximately 4 months prior to wanting to conceive in order to learn the three methods properly. Each consultation is approximately 1 hour to obtain your full case history and teach you how to chart your menstrual cycles. The consultation includes instruction in identification of fertility at mid-cycle through observation of body symptoms and monthly cycle charts to record observations as well as naturopathic treatment to regulate cycles and for menstrual, hormonal, reproductive and nutritional health.

The Three Gender Selection Approaches:

1.The Shettles method
This method relies on Dr Shettles’ observation of the characteristics of the gynosperm (female-chromosome-carrying sperm) and androsperm (male-chromosome-carrying sperm) as set out earlier. To take advantage of these different qualities, he recommends different procedures including intercourse positions, douches, timing in cycle etc to favour either gynosperm or androsperm.

2.The Dietary method
This method, involves a dietary plan based on the theory that eating specific foods affects the pH in the female reproductive tract which in turn will favour the androsperm or gynosperm. Boy or Girl? by Dr Francois Papa and Francoise Labro, Souvenir Press, UK, 1984 is the book written by the French doctor, who has used the method extensively and claims an 80 per cent success rate for sex selection by placing the prospective mother on a particular diet for at least one full month before the conception. Evidence was shown that sea worms immersed in a potassium solution produce males, and those in a magnesium solution, females. The diets I prescribe contain foods that are high in calcium and magnesium (for girls) and sodium and potassium (for boys). I also prescribe specific nutrients to optimise this pH.

3. Lunar Cycle
Dr Jonas, the Czech psychiatrist who was responsible for discovering and researching the lunar cycle of fertility and using it both for contraception and helping raise the odds in infertile situations, also claimed a very high rate of success for his sex selection theory based on the position of the moon. This may sound very esoteric but we forget that the moon governs all of the Earth's ocean tides and therefore our shipping channels around the world. It has an enormous influence on the Earth as well as our bodies, given we are also made up of 70% water.

He claims that when the moon is in a positive (male) sign of the zodiac, a boy is conceived, and vice versa. This is possibly connected to the effect of the moon on the acidity or alkalinity of the secretions of the endometrium and vagina, which then favour either gynosperm or androsperm

It is obviously recommended to combine all 3 methods to maximise results rather than simply using one method alone.

To quote Dr Jonas, ‘The worst that can happen is that a child is born whose sex is the opposite of what was wished for. However, this has happened before!’
