The kin selection hypothesis posits that male androphilia (male sexual attraction to adult males) evolved because androphilic males invest more in kin, thereby enhancing inclusive fitness. Increased kin-directed altruism has been repeatedly documented among a population of transgendered androphilic males, but never among androphilic males in other cultures who adopt gender identities as men. Thus, the kin selection hypothesis may be viable if male androphilia was expressed in the transgendered… 

Transgendered Male Androphilia in the Human Ancestral Environment

TLDR
Research indicates that the mothers, paternal grandmothers, and maternal grandmothers of fa’afafine produce more offspring than those of male gynephiles, which is consistent with the Sexually Antagonistic Gene Hypothesis, and research indicating that the fa�'AFafine’s avuncular cognition exhibits elements of adaptive design.

Evolutionary Perspectives on Male Androphilia in Humans

TLDR
Research has repeatedly furnished support for the Kin Selection Hypothesis in Samoa where transgendered male androphiles (fa’afafine) exhibit elevated avuncular tendencies compared to women and gynephilic men.

Evolutionary Developmental Perspectives on Male Androphilia in Humans

TLDR
Evidence suggests that the transgender form was likely ancestral to the sex-gender congruent form, and research has repeatedly furnished support for the kin selection hypothesis in Samoa where transgender male androphiles (fa’afafine) exhibit elevated avuncular tendencies compared to women and gynephilic men.

Evolving research on the evolution of male androphilia

TLDR
Research indicates that the mothers, paternal grandmothers and maternal grandmothers of fa’afafine produce more offspring than those of male gynephiles, which is consistent with the Sexually Antagonistic Gene Hypothesis, and research indicating that the fa�’AFafine’s avuncular cognition exhibits elements of adaptive design, indicates that they have a common etiological basis.

Femininity and Kin-Directed Altruism in Androphilic Men: A Test of an Evolutionary Developmental Model

TLDR
Findings suggest that femininity is key to the expression of kin-directed altruism among androphilic males and may have been important in the evolution of male androphilia.

Elevated Kin-Directed Altruism Emerges in Childhood and Is Linked to Feminine Gender Expression in Samoan Fa’afafine: A Retrospective Study

Androphilia refers to sexual attraction toward adult males, whereas gynephilia refers to sexual attraction toward adult females. The kin selection hypothesis posits that androphilic males help kin

Is Male Androphilia a Context-Dependent Cross-Cultural Universal?

TLDR
The results show that male same sex behavior as well as male androphilia is much more common than previously estimated in the standard cross-cultural sample (SCCS), making an argument that male andphilia is a context-dependent cross- cultural universal.

Two Behavioral Hypotheses for the Evolution of Male Homosexuality in Humans

TLDR
It is argued that the modern notion of sexual identity has corrupted the understanding of sexuality as a fluid and functional product of evolved cognitive mechanisms, and reliance on categorical sexual archetypes subverts the ability to characterize sexual variance.

Comparative Reproductive Output of Androphilic and Gynephilic Males in Samoa

TLDR
It is contended that absence of reproductive output is a near absolute cross-cultural universal characterizing non-Western, transgendered androphilic (“third-gender”) males.

Familial patterning and prevalence of male androphilia among Istmo Zapotec men and muxes

TLDR
This is the first study that has compared cisgender and transgender androphilic males from the same high fertility population and demonstrated that the two do not differ with respect to the familial patterning of male androphilia.

Sexual Orientation in Men and Avuncularity in Japan: Implications for the Kin Selection Hypothesis

TLDR
The research presented here suggests that a collectivistic cultural context is insufficient, in and of itself, for the expression of an adaptively designed avuncular male androphilic phenotype.

Male Sexual Orientation and Avuncularity in Canada: Implications for the Kin Selection Hypothesis

TLDR
Canadian androphilic men exhibited a significantly greater cognitive dissociation between altruistic tendencies directed toward kin versus non-kin children relative to gynephilic men and androphobic women, consistent with the Kin Selection Hypothesis.

Avuncular Tendencies and the Evolution of Male Androphilia in Samoan Fa’afafine

TLDR
The greater avuncular tendencies of fa’afafine relative to gynephilic men are consistent with the predictions of the kin selection hypothesis for male androphilia, however, further research is needed before deeming male andphilia an adaptation for promoting elevated av uncularity.

Does Geographic Proximity Influence The Expression of Avuncular Tendencies in Canadian Androphilic Males

TLDR
Canadian androphilic males exhibited significantly higher avuncular (uncle-like) tendencies when comparing groups for willingness to engage in altruistic behavior towards nieces and nephews that could be performed from a distance, according to the Kin Selection Hypothesis.

Offspring Production among the Extended Relatives of Samoan Men and Fa'afafine

TLDR
This study compared the reproductive output of the paternal and maternal line grandmothers, aunts, and uncles of 86 Samoan androphilic males, known locally as fa'afafine, and 86 Samoa gynephilic males and suggested that male androphilia is associated with elevated reproduction among extended relatives in both the maternal and paternal line.

Comparative Reproductive Output of Androphilic and Gynephilic Males in Samoa

TLDR
It is contended that absence of reproductive output is a near absolute cross-cultural universal characterizing non-Western, transgendered androphilic (“third-gender”) males.

Is Transgendered Male Androphilia Familial in Non-Western Populations? The Case of a Samoan Village

TLDR
The present study indicated that transgendered male androphilia is familial in this particular Samoan village, thus adding to a growing literature demonstrating that male andphilia and gender atypicality have consistent developmental correlates across populations.

Maternal Inheritance and Familial Fecundity Factors in Male Homosexuality

TLDR
The familial history of male homosexuality is examined, and the so-called “fertile female” hypothesis for this trait in a contemporary British sample is tested, to find that white and non-white homosexual men had a significant excess of maternal but not paternal line male homosexual relatives compared to heterosexual men.

Birth order and male androphilia in Samoan fa'afafine

TLDR
Results indicate that relative to gynephilic males, fa'afafine tend to have more siblings and are generally later born when birth order is quantified using Slater, fraternal and sororal indices.
