You ARE either Male(w testes) or Female(w ovary)

Biology

Humans have sexual reproduction organs called gonads. Females have ovaries.  Males have testes

The developmental biology of humans defaults to producing a female. If there is a functioning SRY gene present and with normal functioning developmental biology a male will be produced. 

The SRY gene is normally on the Y chromosome. 

EXCEPTION In extremely rare (1:100,000) instances of birth defects or developmental disease affecting genes and normal development there can be an individual born with ambiguous or malformed genitalia and/or who is unable to develop into a fully formed adult. The result can be an individual without a functioning gonad, with impaired functioning of one type of gonad, with one gonad if one type and a not fully developed gonad of the second type. There has never been an individual with both a functioning ovary and functioning testes. 

Adults should be free to claim to be whatever sex they want to be: male, female, trans-male, trans-female, binary, fluid, etc,. But there are issues with letting everyone act however they want including but not limited to; trans females competing with females in sports; trans females with male genitalia exposing themselves to females.  There can also be issues with gender conversion treatments and procedures for children because, for the most, part these are irreversible and result in sterility and lack of sexual satisfaction. Gender conversion of children should be limited to rare instances where due to genetic and/or hormonal aberrations it is clear that such treatment is warranted.

And last, people should be free to have loving and sexual relationships with whichever consenting adults they choose. 

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.

 Sexual Identity

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
