The longevity increase associated with bisexual therapies has led to very sophisticated surgical and hormonal treatments for interventions in utero, in puberty, and during adulthood. The XX/XY dichotomy still exists, but in the context of a wide variety of habit, usage, and terminology
feeling of gender identity is formed in the hippocampus and hypothalamus in the second month; the original orientation is persistent. If the desire is to create a feeling of undifferentiation or ambivalence, alterations need to begin in utero
in the first eight weeks of gestation keep both the Müllerian and Wolffian ducts active, in what is still the bi-potential gonad. Anti-Müllerian hormones activated by genes in the Y chromosome can be allowed to attach only to one of the fetal Müllerian ducts. The effect is normally ipsilateral, each testis suppressing Müllerian development only on its own side, so
XY embryos then need a moderate level of androgen insensitivity introduced by the fourth week, in order to avoid masculinization of the hypothalamus, where sexual differences in the brain will be concentrated. XX embryos need the application of androgens to one Müllerian duct in order to stimulate the growth of a Wolffian duct. As that Wolffian duct develops, the Müllerian duct on that side will experience apoptosis
underlying genetic makeup is the difference between androgyny and gynandromorphy, often not discernable by body features. XX humans with conserved Wolffian ducts are gynandromorphs; XY humans with conserved Müllerian ducts are androgyns. In both, androgens and estrogens are supplied with hormone pumps such that the child is born with potential for both kinds of genital development in the body, awaiting the choices
prenatally selected bisexuality has the strongest positive correlation with longevity. Hormonal treatments begun at puberty or during adulthood also have positive effects on longevity, but the psychological set will be
hormonal treatments support the surgical addition of a functioning uterus in the abdominal wall above the penis
alteration of the clitoris into a small functioning penis, with testicles grown using either conserved Wolffian ducts or stem cells from the subject. Gynandromorphs can ordinarily father only daughters, as the construction of a Y chromosome from an X chromosome involves problematic
females adding functional reproductive masculinity are helped by a process imitating a natural 5-alpha-reductase deficiency
principal categories of self-image for gender include feminine, masculine, androgynous, gynandromorphous, hermaphroditic, ambisexual, bisexual, intersex, neuter, eunuch, nonsexual, undifferentiated, gay, lesbian, queer, invert, homosexual, polymorphous, poly, labile, berdache, hijra, two-spirit,
cultures deemphasizing gender are sometimes referred to as ursuline cultures, origin of term unknown, perhaps referring to the difficulty there can be in determining the gender of bears
