Before the release of TDF, the developing fetus has two tiny structures, the mullerian and wolffian ducts, and two small undifferentiated gonads, neither testes nor ovaries. Without the influence of TDF and testosterone, the gonads form into ovaries and the mullerian duct forms into the female internal sex organs, the wolffian duct disappears and the external sexual tissue becomes the labia major, clitoris, labia minor and clitoral hood. With the influence of TDF, the gonads become testicles and the wolffian duct forms the male internal sex organs, the mullerian ducts dissolve and the external tissue develop into the penis, scrotum, penile sheaths and foreskin. In other words, without testosterone all fetuses develop into females. Adam springs from Eve, not Eve from Adam.

As the primary sexual differentiation proceeds towards our physical gender, sometimes deviations occur. These anomalies are sometimes called "experiments of nature." One such "experiment" is a condition termed congenital adrenal hyperplasia (CAH) when the female fetus releases a steroid hormone form her adrenal glands which resembles testosterone. The resulting child often has confusing genitals ranging from deformed female genitals to an appearance of male genitals. If the child is raised as male, following any "adjusting" surgery and given male hormones at puberty, the individual develops as a "normal" but sterile male with XX chromosomes. On the other hand, if the infant is surgically corrected to female and given female hormones, there is a 50/50 chance of lesbian expression.

Another revealing "experiment of nature" is Androgen Insensitivity Syndrome. In this case, there is normal amounts of testosterone circulating in a XY chromosome fetus, but each cell of its body is unable to react to it. This is similar to Turner’s Syndrome in that neither the mullerian or wolffian ducts mature and the external genitalia develops into an approximation of normal female genitals, but differs in that TDF stimulates the gonads into becoming functioning testicles in a XY chromosome body. The child is raised as a girl and is seen as a normal female until she fails to menstruate because she has no uterus. If enough estrogen is produced by her testes, she develops into a completely normal appearing, sterile female with XY chromosomes and internal testicles.

Now we must leave the comfortable arena of biology and development and enter the more rocky, emotional and even political arena of psychology, anthropology, and sociology. An arena where deduction, speculation and circumstantial evidence is more evident than "hard fact."

The third, forth and fifth attributes all reside in the brain and there is controversy on both a congenital vs. environmental level and on a developmental one. It is still argued by some that sexual orientation is a choice and there is no difference in the mental abilities of men and women. Others argue that the evidence, both direct and circumstantial, is becoming overwhelming that these stands are incorrect.

Because of the controversy over whether significant differences in brain structure do exist between the genders, I will confine my discussion of the "Brain Sex" attribute to some behavioral differences that have been noted between morphological male and female infants and children. At all times keep in mind that Physical Gender does NOT always indicate "Brain Sex" Gender. And, while these differences are the norm, they are not absolute. Individual children may differ.

Even a few hours after birth, significant behavioral differences are noted between morphologically normal boys and girls. Newborn girls are much more sensitive to touch and sound than their male counterparts. Several day old girls spend about twice as long looking back at an adult face than boys, and even longer if the adult is speaking. A girl can distinguish between the cries of another infant from other extraneous noises long before a boy. Even before they can understand language, girls do better at identifying the emotional context of speech.

Conversely, during the first few weeks of infant life, boys are inattentive to the presence of an adult, whether speaking to the infant or not. However, baby boys tend to show more activity and wakefulness. At the age of several months, girls can usually distinguish between the faces of strangers and people they know--boys usually do not demonstrate this ability.

As infants grow into children, the differences seem to intensify and polarize. Girls learn to speak earlier than boys and do a better job of it. Boys want to explore areas, spaces and things, girls like to talk and listen. Boys like vigorous play in a large space where girls like more sedentary games in smaller spaces. Boys like to build, take things apart, explore mechanical aspects of things and are interested in other children only for their "use" (playmates, teammates, allies, etc.). Girls see others more as individuals--and will likely exclude a person because their "not nice," and will more readily include younger children and remember each other’s names. Girls play games involving home, friendship, and emotions. Boys like rough, competitive games full of "‘zap, pow’ and villainy." Boys will measure success by active interference with other players, preferring games where winning and losing is clearly defined. In contrast, girl play involves taking turns, cooperation and indirect competition. Tag is a typical boy’s game, hopscotch is a girl’s game.

If "Brain Sex" is controversial, the fourth attribute of Sexual Orientation is ever more so. Although there is public and political controversy, the overwhelming majority of medical and psychological practitioners agree that sexual orientation may prove to be mainly congenital, or at least firmly established in early childhood. The term "Sexual Orientation" is a bit misleading. It is more an erotic or love orientation in that Sexual Orientation determines the physical gender we find attractive, with whom we fall in love, and have romantic as well as sexual fantasies.

From experiments with animals, "experiments of nature" in humans, and genetic and neurological studies come a consistent, though still circumstantial, stream of evidence that indicates one’s sexual orientation is largely hormonally determined by the presence of testosterone at key periods in fetal development, and possibly even beyond. As we have seen with congenital adrenal hyperplasia (CAH), female fetuses exposed to testosterone-like agents develop a 50/50 chance of a lesbian versus heterosexual orientation if raised as girls. Studies of identical twins also indicate that when one twin shows homosexual or lesbian expression, there is a 50/50 chance of homosexual or lesbian expression in the other twin—whether raised together or apart.

The remaining 50% of determination may be continued hormonal development, environmental considerations or a combination. One interesting consideration with determination may be during our early postnatal development since the fetal stage for human babies is not completed during gestation, but continues for a year or more outside the womb. And during this critical time after birth, we have the highest level of testosterone present, excluding the onset of puberty--with many brain receptors to receive this powerful hormone. At any rate, between the ages of three and six years, one’s erotic orientation is established but may not be acted upon for decades, if at all.
