Mark Twain said once: “Rumors of my death have been greatly exaggerated.” If environmental factors in sexual orientation could talk, they might say the same thing. For sure, social or family factors in influencing sexual attractions have been written off by numerous scholars and media. However, a new Danish study may prompt a fresh evaluation of the role of social factors in sexual orientation.
The study, to be published in the October, 2006 issue of Archives of Sexual Behavior by Danish epidemiologist Morten Frisch and statistician Anders Hviid reported the analysis of data from two million men and women. The research suggests a link between environmental factors such as geographic birthplace and family relationships and the probability of marrying a same-sex or opposite-sex partner. The massive study also finds that the number of brothers and sisters increases the probability of marrying heterosexually. This finding contradicts a recent, widely touted Canadian study of birth order that found the number of older brothers increased the probably of homosexuality in men.
The Danish researchers found no evidence that having older brothers increased the likelihood of men marrying homosexually. On the contrary, they found that older siblings increased the probability of heterosexual marriage. The choice of homosexual versus heterosexual marriage serves as an obvious, although not perfect, assessment of sexual preferences.
Regarding the fraternal birth order effect, the authors said, “…we found no indication that older brothers were particularly common in these homosexual men.”
The researchers found for each additional year one’s parents stay married, the probability of heterosexual marriage in the children increased by 1.6% among sons and 1.0% among daughters. In contrast, the rate of homosexual unions decreased by 1.8% among sons and 1.4% among daughters for every year of intact parental marriage. Summing these effects over years of childhood and adolescence contributes to a noteworthy impact.
Regarding homosexual marriages, the researchers found that birth place relates to the sexual orientation of marriage partner. Being born in urban settings increased the probability of homosexual marriage and decreased the probability of heterosexual marriage. Frisch and Hviid noted, “…our study may be the first to show that birth place or some correlate thereof influences marital choices in adulthood.”
The authors also confirmed previous research suggesting that children who experience parental divorce are less likely to marry heterosexually than children reared in intact families.
Frisch and Hviid reported that “for men, unknown paternal identity, parental divorce, short duration of cohabitation with both parents, and long duration of father-absent cohabitation with mother were all associated with increased rates of homosexual marriage.”
For women, homosexual marriage rates were elevated among women whose parents were married briefly, and those who experienced long periods of mother absence due either to abandonment or death during the teen years.
Taken together, the study’s findings suggest that intact parents bearing multiple children, living in rural areas increase the probability of heterosexual pairings in their children.
This study was not designed to examine all possible contributions to sexual orientation nor does it account for individual situations. We know, for instance, that gays and straights come from all kinds of families and locations. What the Danish study does, however, is raise the possibility that family and social factors function to help shape adult sexual orientation, in combination with whatever biological factors may also operate. Also, by questioning the fraternal birth order effect in male homosexuality the study calls for additional studies to assess the theory based on high-quality data from other settings and by independent research teams.
In an interview, Dr. Frisch stressed, “Prenatal factors alone can not account for the variation in human sexual orientations - otherwise, all our urban/rural and family-dynamic findings should have shown no association.”
The study adds support to the theory that environmental and biological factors work together to influence sexual attractions and behaviors. Dr. Frisch concluded, “…whatever ingredients determine a person’s sexual preferences and marital choices, our population-based study shows that environmental factors are important.”
Thus, environmental influences, rumored to be irrelevant, are actually alive and quite well.

The gay activists are so eager to say that homosexuality is natural, that there are gay penguins, gay elephants, etc.
It seems like there are a lot of theories but nobody really knows for sure what causes homosexuality.
So let the scientists study and see where the science leads. The gay activists seem to have a vested interest in certain conclusions being drawn. But that's not how scientific research is supposed to work. The researchers should follow wherever the trail leads, without preconceived notions about what causes certain behavior or inclinations. We wouldn't conduct research in other areas with prejudicial thinking.
so are liberals in denial about sciene?
Yeah, environmental factors like absentee or abusive fathers; domineering mothers; and popular culture that tells kids that their natural revulsion for homosex is an unfair bias they should overcome.
don't leave out the recruiters.
The correlation between adult homosexuality and a history of being molested as a child or adolescent could use some thorough study.
"So, you see, we shouldn't oppose this lifestyle because it's natural, or if it isn't natural, then it's my choice, and if it's not my choice, then you can't blame me or oppose it, and if it is my choice, why, then it's my choice..." Haven't we heard it all over and over and over... and over...???
