Using a nationally representative sample of young adults, I identify the family-demographic correlates of sexual orientation in men and women. Hence, I test the maternal immune hypothesis, which posits that the only biodemographic correlate of male homosexuality is the number of older brothers, and there are no biodemographic correlates of female homosexuality. For men, I find that having one older brother does not raise the likelihood of homosexuality. Although having multiple older brothers… 

Fraternal Birth Order, Family Size, and Male Homosexuality: Meta-Analysis of Studies Spanning 25 Years

The fraternal birth order effect is the tendency for older brothers to increase the odds of homosexuality in later-born males and in homosexual subjects with masculine versus feminine gender identities is compared and evidence for the reliability of the effect was consistent.

Detecting and Correcting for Family Size Differences in the Study of Sexual Orientation and Fraternal Birth Order

Two fraternal birth order studies published in the last 5 years were surveyed for failures to find a statistically significant excess of older brothers for the homosexual group and suggested that the mean family size of the homosexual groups was smaller than that of the heterosexual comparison groups.

Birth Order and Sibling Sex Ratio of Children and Adolescents Referred to a Gender Identity Service

The greater frequency of only children and elevated numbers of older sisters among the homosexual female group adds to a small literature on sibship characteristics of potential relevance to the development of gender identity and sexual orientation in females.

The Effect of Religious Background on Sexual Orientation

Does religious background influence sexual orientation? Research on the etiology of sexual orientation has focused almost exclusively on biological influences; however, the evidence suggests that

Findings support the existence of two maternal immune responses influencing male sexual orientation and possibly also cross-gender behavior and identity.

Gender Nonconformity and Birth Order in Relation to Anal Sex Role Among Gay Men

The results suggest that the fraternal birth order effect may apply to a subset of gay men who have a bottom anal sex role preference and that this subgroup is more gender-nonconforming, but there were no significant associations between fraternalBirth order and gender nonconformity at the individual level.

THE RELATION OF BIRTH ORDER TO SEXUAL ORIENTATION IN MEN AND WOMEN

Results are consistent with the hypothesis that the high birth order of homosexual men reflects the progressive immunization of certain mothers to H-Y antigen by succeeding male fetuses, and the increasing effects of H- Y antibodies on sexual differentiation of the brain in succeeding male Fetuses.

Homosexuality in men and number of older brothers.

The range of possible theories of the birth order phenomenon is restricted to those that can explain not only why older brothers increase the probability of homosexuality in later-born males but also why older sisters neither enhance this effect nor counteract it.

Evidence of familial nature of male homosexuality.

There is a significant familial component to male homosexuality, with heterosexual index men having about as many homosexual brothers as would be predicted given national prevalence figures for homosexuality, but homosexual index men had about four times as many gay brothers, although in both cases most brothers were heterosexual.

Fraternal Birth Order and the Maternal Immune Hypothesis of Male Homosexuality

The maternal immune 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.
