This thread is analogue of thread «нейронаучный вестник» in English. Here I will public references on scientific studies and news relevant to sexuality and to fundamental neurobiology.

 And let's  start with this  news    Is spontaneous change of sexual orientation possible?

Coarse disruption of masculinization of the brain in male rats dose not eliminate masculine sexual behavior, although produce disinhibition of female sexual behavior. What does it mean? Prenatal factors are not the most critical factors in the development of sexual behavior...Realy?

What about sexual behavior of genetic male mice with complete androgen insensitivity syndrome? These mice have female phenotype with male sexual behavior (they try to mount female mices), because estradiol is critically needed in sexual differentiation of the mouse brain. It means that testosterone produces its effect indirectly in the process of sexual differentiation of the brain, specifically testosterone is aromatized, converted to estradiol by special ferment, and then effect of estradiol is mediated by nuclear estrogen receptors. Therefore these mice despite their mutation have properly functioning biochemical machinery of sexual differentiation of the brain.

But humans with this condition have not only female phenotype, they also have female gender identity and female sexual behavior! What does it mean? Any ideas?

It is a fascinating book about the biological and psychological studies on homosexuality. Author’s view on sexual orientation is based on modern neuroscience and, in my opinion, is not biased by political agenda.

I totally recommend to everyone who is interested in sexual orientation research to read this book.

I am reading this book now with great pleasure.

It is one of the rare studies of fetishism. The paper was published in 1996, one year before the death of senior author of the study, Kurt Freud. If you don't know who is Kurt Freud shame on you!

And big thanks to Michael Seto for sharing this wonderful paper with us in researchgate.

Дочитал наконец :)
Цитата:
В заключение исследования убедительно свидетельствуют о том, что рассмотренные половые особенности, присутствующие в КС, конкретно не связаны с синдромом, но более вероятно, связано с основной гипогонадизм. Гипогонадизм, более хромосомной аномалией, может лежать в основе изменения в эмоциональном мозге наблюдается у больных КС. Гипогонадизм также подкрепляет высокий риск гипертриглицеридемии и сексуальной дисфункции, наблюдаемой в КС.

И, наконец, можно предположить, что ТРТ может производить улучшение КС-связано с повышенным риском МетС и CV, помимо улучшение половой функции. Однако дальнейшие исследования вмешательства необходимы, чтобы подтвердить эту гипотезу.

В соответствии с этой точкой зрения, раннее распознавание и TRT было зарегистрировано не только значительно улучшить минеральную плотность костной ткани, жировой массы тела, силы, целенаправленную мышление и чувство собственного достоинства, но и сексуальной дисфункции (Myhre и др, 1970;. Бекер , 1972; Skakkebaek и др, 1981;.. Nielsen и др, 1988;. Кюблер и др, 1992;. Zitzmann и др, 2002; Nieschlag и Behre, 2004; Zitzmann и Nieschlag 2004).

Поэтому мы полагаем, что TRT следует начинать как можно скорее для того, чтобы вернуть в исходное состояние гипогонадизм связанных признаков и симптомов (в том числе и сексуальной дисфункции), а также, чтобы избежать нежелательных последствий андрогенной недостаточности.
В конце любопытный вывод :)

В целом согласен, хотя я тут не специалист, опыта мало.

New Cantor's article about pedophilia. More importantly this article is devoted to nonoffending pedophiles.

I have understood why sleep deprivation can alleviate depression symptoms.

"The study also found that rapid eye movement sleep (REM) deprivation may alleviate clinical depression because it mimics selective serotonin reuptake inhibitors (SSRIs). This is because the natural decrease in monoamines during REM is not allowed to occur, which causes the concentration of neurotransmitters in the brain, that are depleted in clinically depressed persons, to increase. "

The idea is interesting. But I personally prefer "RDT" ("medical fasting") with a similar purpose. Sleep deprivation can distract from work and social life, and "RDT" - virtually no negative effect on it, does not interfere. The effect on these biochemical processes in the brain, the body - rather predictable known.
While I have no objection against the use in complex therapy and this method. The criterion - the relative efficacy and harmlessness.

Apparently, I also treat with respect and attention the author of this book, this direction. Although I myself go on a different path.

I gave a rapid look at the book but I cannot believe there is so much shift toward heterosexual attra tion during adult age... is the author so reliable?
I believe in kirill theory about neuroplasticy of the brain (why is this not considered in paraphilias and homosexuality?).
Do you know some people that is became more heterosexual with some psychoterapy? I don t know anyone...

I agree! I'm gay and I know that no one has become heterosexual as a result of psychotherapy, although even in modern history there have been many attempts to "convert" gays.

I do not trust the authors affiliated with NARTH.

Sorry for the errors, I translate Google Translator.

You could check references in the book. I checked his claims, in general they are right, but he was not very exact, but it is popular science book, not strictly scientific, so some exaggeration could be tolerated, but readers should remain critical. Whitehead also mentioned neuroplasticity, but he didn’t elaborate this topic discussing mechanism of neuroplasticiy. In fact he made only few references on the literature about this topic quoting Norman Doidge’s book “The brain that changes itself”. Norman in chapter about sexuality described sadomasochism in details and made very interesting theoretical conjectures about the etiology of this condition: fusion of different brain systems.

Changing sex arousal toward children is necessary. "Bisexualizing" homosexual people can considered ethical correct?
I mean... we dont know exactly why a person is homosexual, so going to psychoterapist for "bisexualizing" can be a sufference for them? Because maybe exploring themselves can reveal paining trauma...

The question arises, what is heterosexual attraction :)
And why is a gay man who "became a little heterosexual" - remains gay, but a hetero who has become a little gay - refers to gays?



I believe in kirill theory about neuroplasticy of the brain (why is this not considered in paraphilias and homosexuality?).
I'm considering, of course. This is our general theory with Kirill :)

I know such people, it's my job :)
Moreover - you can see them here on the forum. And to talk :)

There is a more difficult and unpleasant option - when a person does not perceive what happened to him as an injury!
When he himself protects his .. not executioners, but those who determined his development in this direction.
Psychotherapy in this case is more difficult, and sometimes impossible.

Why "bisexualizing" go to psychotherapy? Why, in this context, is non-heterosexuality viewed as the result of trauma?
Usually this is the result, as a result of studying the past of this child or adult.
Another issue is that heterosexual people also have traumas, and even stronger ones, often.
Therefore, we are interested in a reliable, true analysis of the past - without prejudice!
IMHO.

Is it possible that heterosexuality is the result of trauma? Does it happen that the gay traumatized in childhood and he became heterosexual? It is incorrect to treat any non-heterosexuality as an injury. Do not you think so?
No, I do not think so.
But in a different sense.
And heterosexuals have traumas.
However, injuries are very different from each other, and people are very different from each other.
Therefore, we analyze the entire childhood, the past of man - and not just "looking for only what looks like a trauma."

Then why in this thread are only the so-called "injuries" of gays and bisexuals considered? When will viewed heterosexuals injuries in the thread?
