Abstract
"Se está llevando a cabo un experimento antropológico, con aplicación de biotecnología, iniciado sin garantía de éxito. Puede sintetizarse en la idea cultural de superación de los dos sexos biológicos. Sin embargo, es un hecho que el sexo corporal está determinado en la herencia recibida a nivel del par de cromosomas sexuales XX o XY. Los órganos gónadas y cerebro, al igual que las estructuras secundarias sexuales, «tienen» sexo. Los experimentos de la biotecnología con roedores para conseguir gametos in vitro desde células inmaduras de macho o de hembra, o cambiar el tipo de gameto que genera un organismo macho, o a la inversa, no ha dado resultados, que pudieran extrapolarse a humanos. Hoy por hoy, transmitir la propia vida de forma independiente de la identidad biológica corporal es mera ciencia ficción. El desarrollo armónico, que aporta y mantiene la identidad personal, permite que coincida el sexo cerebral y psicológico con el corporal. Las personas transexuales se sienten del sexo opuesto al de su cuerpo. La causa, que es genética, hace que en la etapa prenatal de la vida el cerebro esté expuesto a un exceso de esteroides. Investigaciones recientes sugieren una disfunción en la percepción cerebral del propio cuerpo, que no es una simple cuestión de preferencia dependiente del entorno social o del aprendizaje. Por ello, se debate que la armonía psique/corporalidad se alcance con las intervenciones quirúrgicas y los tratamientos hormonales que cambian el sexo genital y los caracteres sexuales secundarios. Existen, además, personas con condición intersexual, de origen genético, con un trastorno del desarrollo gonadal –«ovotesticular»–, que presentan ambigüedad en las estructuras gonadales y en los genitales. Se trata de una malformación que no conlleva efectos cerebrales, ni transexualismo. Los investigadores recomiendan no tener prisa en asignarles desde el nacimiento un sexo, de forma arbitraria". ["An anthropological experiment with the application of biotechnology is being conducted, although without any guarantees of success. It might be summarized within the cultural idea of overcoming the existence of two sexes. However, it is a fact that body sex is determined by a heritage of sex chromosomes XX or XY. Gonads and brain, as well as secondary sexual structures, «have» sex. Biotechnology experiments with rodents to obtain gametes in vitro from immature cells of male or female, or change the type of gamete generating a male body or vice versa, have yielded no results that could be extrapolated to humans. Today, transfer of life independently of body’s biological identity is mere science fiction. The harmonious development, which provides and maintains personal identity, can match brain sex and psychological, with the body. Transsexual people feel the opposite sex of their body. The cause is genetic, generated in the prenatal stage of life when the brain is exposed to excessive steroids. Recent research suggests a dysfunction in brain’s own body perception, and not a simple matter of choice depending on social or learning environment. Thus, it is argued that harmony psyche / body is achieved with surgery and hormone treatments that change the genital sex and secondary sexual characteristics. There are also people with intersex condition, genetically based, with a disorder of gonadal development –«ovotesticular»– that have ambiguity in the gonadal structures and genitals. This is a malformation that involves no brain effects of transsexualism. The researchers recommend no hurry to assign a sex at birth, arbitrarily".]
