SELECTION OR DETERMINATION
OF BABY GENDER

Selection or determination of baby
gender is an important part of the family planning process.
Technically it is more complicated than calculating the optimal
time of conception. Predicting baby gender can only be done with
mathematical modeling of the Energy Exchange of the partners’
reproductive systems and defining the optimal state of these
systems.

Many processes are running
simultaneously in the human body and most of them are cyclical
(occurring after the same number of days each period). As more
physical processes are factored in, the model will more accurately
predict the future baby’s gender.

An example of mathematical
modeling of partners’ reproductive systems is shown below. Here,
the red line shows possible times for spontaneous ovulation, the
green line for ordinary ovulation, and the blue line for the peak
of sperm activity. The ideal situation is when both types of
ovulation and the man’s fertility peak coincide. The period of likely male
conception is shown in blue, whereas the period for female
conception is shown in pink. The resulting projection is plotted;
on the horizontal axis all the days of the month are present, with
each vertical line corresponding to 12:00 noon. The vertical axis
is the probability of conceiving a baby with the given gender.

To find the probability, one needs
to imagine a vertical line running from the day of interest to the
curve. Then imagine a horizontal line from this point to the left
axis, which gives us the probability.

In this example, on the evening of
August 7, 2003, the probability of conceiving a boy will be about
86%.
