The first thing to understand, if you want to influence the
gender of your child, is how nature selects the sex of a baby.
This is determined by the sperm. Each sperm contains one
chromosome, an X for a girl and a Y for a boy. Nature has
organized it so that there are slightly more male sperm than
female – for every 100 female sperm there are 110 male ones. The
ovum or eggs also only contain one chromosome but this is always
an X. So if the sperm is carrying an X chromosome and it is
combined with the X in the egg, the fetus will be a XX or girl.
If the sperm is carrying a Y chromosome and it is combined with
the X in the egg, then the fetus will be a XY or boy. Next we
need to look at how the X and Y sperm differ. Y (boy) sperm are
smaller and weaker than X (girl) sperm but they are speedier and
can move faster than their female counterparts. Bearing in mind
that the X (girl) sperm are tougher (and I know we’ll get
comments about THAT in the YinOva waiting room next week!)
