Biological Sex
Females are humans with ovaries and males are humans with testes.
Most babies are born with a clear biological sex. Babies are
made when a sperm from the testes carrying either an x or a y chromosome, fuses
with an egg from an ovary carrying an x chromosome, to create a zygote. The
result 99.78% (1) of the time is a zygote with xx chromosomes or xy
chromosomes.
The zygote then further
divides to form the embryo which continues to develop and differentiate into
various structures, tissue types and organs. One of these organs is the bipotential
gonad that will ultimately develop into an ovary or a testes depending on multiple
complex factors and signals that affect its development. The key factors in this development is the SRY
gene which is normally only on the y chromosome.
The xy embryo, with the SRY gene and normal genetic and
hormonal functioning, will develop into a newborn male with testes. With normal genetic and hormonal functioning, as
the male matures and reaches puberty, increased testosterone production will
further develop the male with the typical male characteristics.
The xx zygote, without SRY and with normal genetic and
hormonal functioning, will develop into a newborn female with ovaries. With normal genetic and hormonal functioning, as
the female matures and reaches puberty, increased estrogen production will
further develop the female with the typical female characteristics.
With inherent normal differences in genetic and hormonal
functioning there is a natural variability of sexual characteristics with each
sex. There can be very masculine males
and less masculine males and the same variability within females.
In rare cases, 1.7% (1), there are conditions called Differences
in Sex Development (DSD) involving genes, hormones, ovaries, testes, reproductive
organs, and genitals, affecting newborn development or the further development
of the adult. These still result in a male or female with either ovaries or
testes, however, depending on the severity of the condition, the appearance, genitals,
reproductive organs, or ovary or testes function can differ significantly from
typical.
And in extremely rare instances, 1:100000 (2), there have
been individuals with both testicular and ovarian tissues, ovotestes, that may
be able to make sperm or eggs, but not both, and whose genitals, reproductive
organs and physical traits can be ambiguous.
There is a great deal of discussion regarding sexual identity
or gender. Recent research indicates that 1.6% of adults consider themselves
transgender, a different sex than assigned at birth, or nonbinary, their sex
can be either or both and vary (3).

Dr. Riittakerttu Kaltiala knows gender medicine. She is the top expert on pediatric gender medicine in Finland and the chief psychiatrist at one of its two government-approved pediatric gender clinics, at Tampere University in Helsinki, where she has presided over youth gender transition treatments since 2011.
Kaltiala thus concurs with NHS England, which recently noted that social transition—using a child’s preferred name and pronouns—is “not a neutral act” but rather one that can solidify what is otherwise likely to be a passing phase into a more permanent state of mind, or “identity,” and put the minor on a path to drugs and surgeries. The NHS now warns of the risks of social transition in children and recommends it only for adolescents who have been diagnosed with gender dysphoria and have provided informed consent.
The Finnish Paediatric Society, the counterpart to the American Academy of Pediatrics, has come out against governmental support for gender self-identification in minors in a statement to the Finnish parliament. Likewise, the Finnish Medical Association wrote that “the decision to limit legal gender recognition to adults is a good one.” These statements run directly counter to the American Academy of Pediatrics
