The neurobiology of sexual partner preferences in rams

Prenatal Programming of Sexual Partner Preference: The Ram Model

TLDR
The results fail to support an essential role for neural aromatase in the sexual differentiation of sheep brain and behaviour and it is proposed that oSDN morphology and male‐typical partner preferences may instead be programmed through an androgen receptor mechanism not involving aromatisation.

Wired on Steroids: Sexual Differentiation of the Brain and Its Role in the Expression of Sexual Partner Preferences

TLDR
The major findings which support the hypothesis that the organizational actions of sex steroids are responsible for sexual differentiation of sexual partner preferences in select non-human species are reviewed.

The androgen receptor is selectively involved in organization of sexually dimorphic social behaviors in mice.

TLDR
It is demonstrated that organization of social and olfactory preferences in mice can be affected by perinatal DHT and lends support to the role of androgen receptor in organization of sexual differentiation of brain and behaviors.

Brain Development and Sexual Orientation

TLDR
Sexual orientation (homo- vs. heterosexuality) is one of many sex differences observed in humans that can result from differential postnatal experiences or from biological factors acting pre- or postnatally.

To What Extent are Prenatal Androgens Involved in the Development of Male Homosexuality in Humans?

TLDR
Some studies suggest that physical measures affected by prenatal androgens, including the index-to-ring finger ratio, growth indices, and facial structure, are more "feminine" in gay men, but many of these results are equivocal and may be confounded by other factors.

The volume of a sexually dimorphic nucleus in the ovine medial preoptic area/anterior hypothalamus varies with sexual partner preference.

TLDR
Results suggest that naturally occurring variations in sexual partner preferences may be related to differences in brain anatomy and capacity for estrogen synthesis.

TLDR
Understanding why same-sex sexual partner preference evolves in some species may involve abandoning a strictly functional perspective and, instead, approaching the issue from the perspective of each species' unique evolutionary history.

TLDR
The results suggest that neurons in the mPOA/AH play an important role in the integration of sensory cues which determine heterosexual partner preference in the male ferret, in addition to facilitating masculine coital performance.

Endocrine correlates of partner preference behavior in rams.

TLDR
The data suggest that the testes of the male-oriented ram have reduced capacity for T production, and the highest level of AA was found in the POA, which was significantly greater in female-oriented than in male- oriented rams.

A Comparison of LH Secretion and Brain Estradiol Receptors in Heterosexual and Homosexual Rams and Female Sheep

TLDR
Results show that the preovulatory LH surge mechanism that is a characteristic of the female does not occur in either homosexual or heterosexual rams, and the ER content of the AMY of homosexual rams is similar to that of ewes and differs from the heterosexual male.

TLDR
Some recent results obtained in oestradiol‐deficient aromatase knockout mice that provide evidence for a developmental role of ostradiol in olfactory investigation of volatile body odours are discussed, suggesting that: (i) oestrogens contribute to the development of the main Olfactory system and (ii) mate recognition is mediated by the main as opposed to the accessory o aroma system.

Luteinizing hormone, testosterone, and behavioral response of male-oriented rams to estrous ewes and rams.

TLDR
Lack of an LH response to sexual activity in homosexual rams was not a result of pituitary or gonadal insensitivity; within 1 h of a single injection of LHRH both LH and T increased.

Sexual Differentiation of the Vertebrate Brain: Principles and Mechanisms

TLDR
There is ample evidence of sexual dimorphism in the human brain, as sex differences in behavior would require, but there has not yet been any definitive proof that steroids acting early in development directly masculinize the humanbrain.
