The interstitial nuclei of the human anterior hypothalamus (INAH1-4) have been considered candidates for homology with the sexually dimorphic nucleus of the preoptic area of the rat. Volumetric sexual dimorphism has been described for three of these nuclei (INAH1-3), and INAH3 has been reported to be smaller in homosexual than heterosexual men. The current study measured the INAH in Nissl-stained coronal sections in autopsy material from 34 presumed heterosexual men (24 HIV- and 10 HIV+), 34… 

Figures and Tables from this paper

Galanin neurons in the intermediate nucleus (InM) of the human hypothalamus in relation to sex, age, and gender identity
Organizational and activational hormone effects on the InM are discussed and a sex difference in the younger age group (<45 years of age) is found and an age difference, with a decrease in volume and Gal‐Ir neuron number in males > 45 years is found.
Sex in the brain . Gender differences in the human hypothalamus and adjacent areas . Relationship to transsexualism , sexual orientation , sex hormone receptors and endocrine status
Women revealed more nuclear ERfJ-ir thann men of a low to intermediat e level, e.g., in the suprachiasmatic, supraoptic, paraventricular, infundibular, and medial mamillary nucleus, which indicate potential sex differences in ERfFJ expression.
A sex difference in the hypothalamic uncinate nucleus: relationship to gender identity.
It is proposed that the sex reversal of the INAH3 in transsexual people is at least partly a marker of an early atypical sexual differentiation of the brain and that the changes in INah3 and the BSTc may belong to a complex network that may structurally and functionally be related to gender identity.
Sex differences in the hypothalamus in the different stages of human life
" " Differential Brain Activation in Exclusively Homosexual and Heterosexual Men Produced by an SSRI
In the hypothalamus, the homosexual group exhibited a significantly smaller reduction in glucose metabolism in response to fluoxetine than the heterosexual group, which might be reflective of underlying neurochemical differences between homosexual and heterosexual men.
Neural correlates of sexual arousal in homosexual and heterosexual men.
Both homosexual and heterosexual men exhibited category-specific arousal in brain activity, and within the amygdala, greater preference-related activity was observed in homosexual men, but it is unclear whether this is a cause or a consequence of their sexuality.

The sexual differentiation of the human brain is most likely a multifactorial process including both sex hormone and sex chromosome effects, acting in parallel or in combination.
The ovine sexually dimorphic nucleus of the medial preoptic area is organized prenatally by testosterone.
Data demonstrate that testosterone acts during a prenatal critical period to organize the development of aromatase-expressing neurons into the male-typical oSDN in sheep.


A difference in hypothalamic structure between heterosexual and homosexual men
The measured volumes of INAH 3 indicate that INAH is dimorphic with sexual orientation, at least in men, and suggests that sexual orientation has a biological substrate.
Two sexually dimorphic cell groups in the human brain
A quantitative analysis of the volume of 4 cell groups in the preoptic- anterior hypothalamic area (PO-AHA) and of the supraoptic nucleus (SON) of the human brain was performed in 22 age-matched male

This finding of a difference in a structure not known to be related to reproductive functions supports the hypothesis that factors operating early in development differentiate sexually dimorphic structures and functions of the brain, including the anterior commissure and sexual orientation, in a global fashion.

It is suggested that androgens continue to exert organizational influences upon the developing brain after cytoarchitectonic patterns have been determined.
Sexually dimorphic regions in the medial preoptic area and the bed nucleus of the stria terminalis of the guinea pig brain: a description and an investigation of their relationship to gonadal steroids in adulthood
Attention to the sex differences in these areas may help elucidate more precisely the neural basis for sexually dimorphic functions, as well as the basic mechanisms underlying sexual differentiation of behavior and the brain.
Development of a Sexually Dimorphic Projection from the Bed Nuclei of the Stria Terminalis to the Anteroventral Periventricular Nucleus in the Rat
It is suggested that a sex- and region-specific activity influences the development of the projection from the BSTp to the AVPV, producing a sexually dimorphic architecture in pathways that convey olfactory information to the hypothalamus.
