REVIEW
Sari M van Anders
Largely based on pre-theory that ties high testosterone (T) to masculinity, and low T to femininity, high T is mainly studied in relation to aggression, mating, sexuality, and challenge, and low T with parenting. Evidence, however, fails to support this, and the social variability in T is better accounted for by a competition-nurturance trade-off as per the Steroid/Peptide Theory of Social Bonds (van Anders et al., 2011). Four key domains are discussed: adult-infant interactions, sexual desire, sexual behavior, and partnering...

Membership in a valued group can provide an individual with a variety of benefits. As a result, people should be motivated to avoid being misidentified as a member of an outgroup, particularly a stigmatized outgroup. We argue that when group membership is not readily identifiable, concern over potentially being mistaken for a member of the outgroup (i.e., social contagion concerns) can be potent and can lead to avoidance of the outgroup. The current work shows that after controlling for negative attitudes toward homosexuality, social contagion concerns independently predict anxiety and avoidance in response to imagined, anticipated, and actual contact with a lesbian or gay individual...

People have a fundamental motive to view their social system as just, fair, and good and will engage in a number of strategies to rationalize the status quo (Jost & Banaji, 1994). We propose that one way in which individuals may "justify the system" is through endorsement of essentialist explanations, which attribute group differences to deep, essential causes. We suggest that system-justifying motives lead to greater endorsement of essentialist explanations because those explanations portray group differences as immutable...

OBJECTIVE: To assess anal oncogenic human papillomavirus (HPV) and anal cytology as screening tests for detecting high-grade anal intraepithelial neoplasia (AIN 2+), as this is an immediate anal cancer precursor. DESIGN: Cross-sectional study of 401 HIV-positive men who have sex with men (MSM). The endpoint was histologically confirmed AIN 2+ obtained by high-resolution anoscopy. Cytology and biopsy specimens were assigned random numbers and independently assessed by two pathologists...

REVIEW
J P De Cecco, D A Parker
This paper begins with a summary of the biological research on homosexuality that occurred in the late 1980s and early 1990s. It then summarizes the treatment of this research chiefly by the print media. It then adumbrates the presuppositions about sexuality and gender upon which the reports were based. It is argued that the presuppositions, which are asserted without being examined, date back to the nineteenth century. They ignore the historical, sociocultural, and humanistic research of the last two decades that collectively comprise the field of gay, lesbian, and bisexual studies...

G Schmidt, U Clement
This study attempted to replicate a series of investigations by Gunter Dörner and his associates that concluded that more homosexual men are born in wartime than in times of peace. That conclusion is based on Dörner's belief that war induces stress in pregnant women and that stress causes a drop in fetal androgen levels which in turn leads to the development of a homosexual "orientation". The replication not only failed to support the Dörner conclusion but also found that even those cities that suffered the most severe bombing during World War II showed no evidence of increased numbers of homosexuals...

W J Turner
Despite the absence of phenotypic manifestations in alternating generations characteristic of X-linked disorders, a thesis is presented that a major type of Kinsey grades 5 and 6 male homosexuality is determined by a gene in the Xq28 region. A total of 133 families in 78 kinshps of male and female homosexual probands, in addition to 116 families (including those of 40 famous homosexuals) from the literature, revealed an unbalanced secondary sex ratio in the maternal generation of male, but not of female, homosexuals...

#12
REVIEW
R Blanchard, P Klassen
In men, sexual orientation correlates with the number of older brothers, each additional older brother increasing the odds of homosexuality by approximately 33%. It is hypothesized that this fraternal birth order effect reflects the progressive immunization of some mothers to Y-linked minor histocompatibility antigens (H-Y antigen) by each succeeding male fetus, and the concomitantly increasing effects of H-Y antibodies on the sexual differentiation of the brain in each succeeding male fetus. This hypothesis is consistent with a variety of evidence, including the apparent irrelevance of older sisters to the sexual orientation of later-born males, the probable involvement of H-Y antigen in the development of sex-typical traits, and the detrimental effects of immunization of female mice to H-Y antigen on the reproductive performance of subsequent male offspring...

Paul Cameron
Homosexual interaction was involved in 11 (48%) of 23 and 10 (45%) of 22, that is, about half of two nationwide databases of newspaper stories about teachers sexual involvement with pupils reported by Cameron and Cameron in 1998. Whether this relationship holds at a local level was examined by searching all indexed 'sex crimes' in the Boston Globe from 1991 through 1998 for local stories about sex between pupil and teacher. Of the 21 teachers in 20 stories, 11 (52%) interacted homosexually with pupils. Thus it appears that nationally and locally, as reported in newspapers, about half of the molestations by teachers are homosexual...

REVIEW
M J MacCulloch, J L Waddington
Theories on the classification and aetiology of male homosexuality are reviewed, particularly recent hypotheses on the role of prenatal hormonal influences on brain sexual differentiation and subsequent sexual object choice in the male. Female as well as male brain sexual differentiation may be hormonally determined, and so primary homosexuality in both sexes may be due to abnormalities in foetal exposure to hormones, leading first to physical mis-differentiation and later to homosexual behaviour in genetically and phenotypically normal men and women...

#16
M King, E McDonald
Forty-six homosexual men and women who were twins took part in a study of their sexuality and that of their co-twin. Discordance for sexual orientation in the monozygotic pairs confirmed that genetic factors are insufficient explanation of the development of sexual orientation. There was a high level of shared knowledge of sexual orientation between members of twin pairs, and a relatively high likelihood of sexual relations occurring with same sex co-twins at some time, particularly in monozygotic pairs. The implications of these results for the study of the origins of sexual orientation and for twin research are discussed...

#17
REVIEW
William H James
This note considers two hypotheses on the causes of homosexuality and paedophilia in men, viz. the hypotheses of maternal immunity and of postnatal learning. According to the maternal immune hypothesis, there is progressive immunization of some mothers to male-specific antigens by each succeeding male fetus, and there are concomitantly increasing effects of anti-male antibodies on the sexual differentiation of the brain in each succeeding male fetus. An attempt is made to assess the status of this hypothesis within immunology...

Peter Zachar, Kenneth S Kendler
We compare astronomers' removal of Pluto from the listing of planets and psychiatrists' removal of homosexuality from the listing of mental disorders. Although the political maneuverings that emerged in both controversies are less than scientifically ideal, we argue that competition for "scientific authority" among competing groups is a normal part of scientific progress. In both cases, a complicated relationship between abstract constructs and evidence made the classification problem thorny.

COMPARATIVE STUDY
A B Chun, S Rose, C Mitrani, A J Silvestre, A Wald
OBJECTIVES: To evaluate the structure and function of the internal (IAS) and external (EAS) anal sphincters in anoreceptive homosexual men and to determine whether anoreceptive intercourse (ARI) is associated with a higher risk of incontinence in this population. METHODS: We studied 14 anoreceptive homosexual males and 10 age-matched non-anoreceptive heterosexual males in a controlled, prospective cohort study. Subjects underwent evaluation of resting and maximum squeeze anal canal pressures (maximum squeeze pressure obtained over resting pressure) by station pull-through technique, using a manometric perfusion catheter followed by endoanal ultrasonography to evaluate the structure of the IAS and EAS...
