However, it is only relatively recently that developmental scientists have conducted controlled studies with one clear aim in mind, which is to go beyond mere stereotypes and accurately identity the most reliable signs of later homosexuality. In looking carefully at the childhoods of now-gay adults, researchers are finding an intriguing set of early behavioral indicators that homosexuals seem to have in common. And, curiously enough, the age-old homophobic fears of parents seem to have some genuine predictive currency.

Overview: We identified 79 scholarly studies that met our criteria for adding to knowledge about the well-being of children with gay or lesbian parents. Of those studies, 75 concluded that children of gay or lesbian parents fare no worse than other children. While many of the sample sizes were small, and some studies lacked a control group, researchers regard such studies as providing the best available knowledge about child adjustment, and do not view large, representative samples as essential.
Elliot Dougherty left with his mother-in-law, Cecile Eledge, her husband Kirk, and their son, Matthew. There are probably only a handful of people across the country who can do this — only a handful of people who have done it. In South Africa, inyear-old Pat Anthony gave birth to three of her own biological grandchildren as triplets — causing an international media firestormand stirring up debates surrounding the ethics of surrogate pregnancy.
A variety of social, developmental, biological and genetic factors influence sexual orientation in males. Thus, several hypotheses have attempted to explain the sustenance of genetic factors that influence male homosexuality, despite decreased fecundity within the homosexuals. Kin selection, the existence of maternal effects and two forms of balancing selection, sexually antagonistic selection and overdominance, have been proposed as compensatory mechanisms for reduced homosexual fecundity.

December 12, Groundbreaking research led by a team from Brock University has further confirmed that sexual orientation for men is likely determined in the womb. In the first-ever laboratory study of mothers of gay men, the research was prompted by more than two decades of statistical data examining the 'older brother effect' which shows that biological older brothers—but not older sisters—increase the odds of homosexuality in later-born males.
Male homosexuality is inborn and may be triggered by a gene carried by mothers, new findings suggest. Evolutionarily speaking, homosexuality as a trait would not last because it discourages reproductive sex with women and therefore procreation. However a new study, published in The Journal of Sexual Medicinefound a correlation between gay men and their mothers and maternal aunts, who are prone to have significantly more children compared to the maternal relatives of straight men. Researchers led by Andrea Camperio Ciani, from the University of Padova in Italy, say that the findings of the link between homosexuality and female fertility strongly support the "balancing selection hypothesis," which suggests that a gene which causes homosexuality also leads to high fecundity or reproduction among their female relatives.
