Do gay people have low testosterone
Evaluation of physical signs of prenatal testosterone exposure in lesbian men
Objective: In recent years, studies regarding the biological etiology of homosexuality possess focused on the sexually dimorphic maturation of the mind during fetal being. Prenatal testosterone may play an crucial role for the differentiation of the brain and sexual orientation (1). Based on this view, homosexuality may be caused by inadequate testosterone levels during the development of the brain. Moreover, prenatal testosterone levels are thought to masculinize 2nd to 4th finger length ratio (2D:4D) as well as other sexually dimorphic features. Women usually include a higher 2D:4D than men. Thus the aim of the present investigation was to judge 2nd to 4th finger length ratio (2D:4D) that is claimed to indirectly reşect the effects of prenatal testosterone levels on intellect in homosexual male individuals.
Methods: The research included 40 men aged 18-35 years, who defined themselves as homosexual and 40 men aged 18-34 years, who defined themselves as heterosexual. A personal questionnaire, which is developed by our group and deeply interested some sociodemographic numbers of subjects, and Bem Sexual Role Inventory (
Brain responses differ in gay, unbent men
The brains of homosexual men respond more like those of women when reacting to a chemical derived from the male sex hormone, new evidence of physical differences related to sexual orientation.
The finding, published in Tuesday’s issue of Proceedings of the National Academy of Sciences, shows differences in physiological reaction to sex hormones.
Researchers led by Ivanka Savic at the Karolinska Institute in Stockholm, Sweden, exposed heterosexual men and women and lesbian men to chemicals derived from male and female sex hormones. These chemicals are thought to be pheromones, molecules known to trigger responses such as defense and sex in many animals.
Whether humans respond to pheromones has been the subject of debate, although in 2000 American researchers reported finding a gene that they believe directs the human pheromone receptor in the nose.
Biological basis to sexual orientation?
In the Swedish study, when sniffing a chemical from testosterone, the male hormone, portions of the brains involved in sexual activity were activated in gay men and straight women, but not in straight men, the researchers found.
When they sn
Most people think of testosterone as a "male" hormone. That is, a hormone that is responsible for much of what we think of as characteristically male such as assertiveness, impulsivity, competitiveness and, of course, sexuality. There is substantial evidence that this is largely correct. Most of this evidence comes from studies on other species, particularly rodents. Many people imagine that humans, with their greater brains, are liberated from the control exerted in other species such as rodents by hormones like testosterone. But are they right? Have we really shrugged off our biological heritage?
When it comes to the sexuality of women, most people would suppose that it is the traditional ovarian hormones, estrogen, and progesterone, that might compete a part, if indeed, women’s sexuality is in any way subject to control by hormones. It’s certainly the case in animals such as rats or cats. Is there any vestige of a similar process in women? But here there is a surprise as well.
Let’s start with males. Rats are born very immature, looking like fetuses. The testes of a new-born male rat secrete testosterone. If the testes are removed, then he grows up to behave more like a female
Homosexuality, one of the many different sexual behaviors exhibited by humankind, has been rejected, persecuted, and denied. Are the studies that seek to find causation moral? Is this search for the "why" of homosexuality a continuation of the heterosexist assumption that heterosexuality is normal and homosexuality abnormal? Are assumptions being made that homosexuality is a disease and should therefore be treated medically? Is the research currently entity done heterosexist? Studies that are entity performed currently and those done in the recent past have shown that there are sturdy connections between male homosexuality and biology. By presenting the scientifically significant studies that I hold come across, I intend to cut down the ignorance surrounding homosexuality and the behaviors often establish with it, and to show some of the correlations between biology and male homosexuality.
Throughout my research of homosexuality, I wavered back and forth, debating the morality of this look for for a lead to. It seemed that finding a result in for homosexuality was somewhat akin to finding the lead to for a disease. Unhappy with the association of homosexuality with abnormali
