Theories regarding biological rhythms were first developed during the 1920's. For more than 40 years, a number of Doctors and Professors from around the World have demonstrated the mathematical regularity and exactitude of these biological rhythms and the way they rule each human life.

Each human being, from the moment they are born, are ruled by their 'biorhythms' or 'circadian rhythm of nature'. It rules the alternance sleep/awakening season and the mechanism of hormonal secretion.

These Doctors and Professors identified three cycles: the 'physical' cycle, the 'emotional' cycle and the 'intellectual' cycle. They also found there is a positive and a negative phase in each cycle.

For example, when both physical and emotional cycles are in a negative phase, that's the day you feel like curling up under the duvet with a cup of tea and hiding from the world! Another example is from Japanese public transport companies - to maximize safety, they give their staff holidays when biological rhythms are at their lowest.
In 1962 and 1963*, in depth studies demonstrated that the mother's biorhythms at the time of her baby's conception are essential in the determination of the baby's sex. The biorhythms, according to their increasing or decreasing phase, modify the alkaline/acidic environment of the vagina as well as the electro-magnetism of the egg (ovum) membranes. As a result, the egg (ovum) is more likely to attract X or Y spem under the biorhythms influence.

* Article published in the 'New York Telegraph', December 28th of 1963
Women are more likely to conceive a GIRL when certain combinations between the emotional cycle and the physical cycle. Their inverse will produce a BOY. In addition, many women always ovulate at the peak of their physical or emotional cycle which explains why some of us tend to have three or four of a kind!
