Hi all

Yes, I really will get to part 3 of the Swaab paper (see earlier posts). With the holidays, I have not had time to summarize the science.

Here’s a little lighter fare for the holiday weekend. I don’t know if these hormones work differently in different sexual orientations. That would be interesting to find out. Grant money, anyone?

This article and others can be found at Hormones and Love

OVER the course of history it has been artists, poets and playwrights who have made the greatest progress in humanity’s understanding of love. Romance has seemed as inexplicable as the beauty of a rainbow. But these days scientists are challenging that notion, and they have rather a lot to say about how and why people love each other.

Is this useful? The scientists think so. (more…)

If you have not heard of Professor Milton Diamond at the University of Hawaii, you really should check out his research. He is one of the leading researchers in the field of transgender and intersex science. His website also has links to a large number of resources for LGBT folks.

Biology of Sexual Identity and Orientation – Part 2 December 22, 2009

Summarized from Sexual Hormones and the Brain: An Essential Alliance for Sexual Identity and Sexual Orientation

For many individuals, their anatomy, gender identity and sexual orientation fit the mold of heterosexual and cisgender. What does this mean? If a person has male genitals, they usually identify as male and like girls. For a long time, we have considered this normal and have used negative, hurtful words to describe humans who are gay, lesbian, bisexual or transgender. We’ve seen it as an illness, a choice, a sin, or just plain freaks.

Most of us don’t realize that our sense of sexuality extends beyond our genitals. (more…)

Over the next few days, I’ll be summarizing this article. I can’t print it in it’s entirety due to copyright restrictions. So I’ll summarize the information in bits and pieces.

Stay tuned. This will get interesting.

Sexual Hormones and the Brain: An Essential Alliance for Sexual Identity and Sexual Orientation

Alicia Garcia-Falgueras  Dick F. Swaab Netherlands Institute for Neuroscience, an Institute of the Royal Netherlands Academy of Arts and Sciences, Amsterdam, The Netherlands

Endocrine Development, 2010, vol 17, pp.22-35


The fetal brain develops during the intrauterine period in the male direction through a direct actionof testosterone on the developing nerve cells, or in the female direction through the absence of this hormone surge. In this way, our gender identity (the conviction of belonging to the male or female gender) and sexual orientation are programmed or organized into our brain structures when we are still in the womb.

However, since sexual differentiation of the genitals takes place in the first two months of pregnancy and sexual differentiation of the brain starts in the second half of pregnancy, these two processes can be influenced independently, which may result in extreme cases in transsexuality.

This also means that in the event of ambiguous sex at birth, the degree of masculinization of the genitals may not reflect the degree of masculinization of the brain. There is no indication that social environment after birth has an effect on gender identity or sexual orientation.

A while ago, I reported a study showing that individuals who had undergone sex reassignment surgery had no regrets. Here is another study, this time from France.

Study of quality of life for transsexuals after hormonal and surgical reassignment

Aim.—The main objective of this work is to provide a more detailed assessment of the impactof surgical reassignment on the most important aspects of daily life for these patients. Our secondary objective was to establish the influence of various factors likely to have an impacton the quality of life (QoL), such as biological gender and the subject’s personality.

Methods.—A personality study was conducted using Eysenck Personality Inventory (EPI) so asto analyze two aspects of the personality (extraversion and neuroticism). Thirty-eight subjectswho had undergone hormonal surgical reassignment were included in the study.

Results.—The results show that gender reassignment surgery improves the QoL for transsexuals in several different important areas: most are satisfied of their sexual reassignment (28/30),their social (21/30) and sexual QoL (25/30) are improved. However, there are differences between male-to-female (MtF) and female-to-male (FtM) transsexuals in terms of QoL: FtM have a better social, professional, friendly lifestyles than MtF. Finally, the results of this study did not evidence any influence by certain aspects of the personality, such as extraversion and neuroticism, on the QoL for reassigned subjects.© 2009 Published by Elsevier Masson SAS.
