Altogether, these clinical cases are consistent with the idea that embryonic hormones play a substantial role in determining adult sexual orientation.

London - Women who suffer stress during pregnancy increase the chance of their child being gay, according to a controversial new book.
The lifestyle of pregnant mothers affects the sexuality of their unborn child, altering their hormones and the formation of their brains, it claims. Smoking or taking drugs can also result in a child who grows up to be gay, according to the book by Dutch neuroscientist Dick Swaab.
In his book, We Are Our Brains, he writes: Professor Swaab says that the development of the brain during pregnancy is altered by the tiniest of chemical changes.
As an example, he claims that a drug prescribed to two million mothers to combat miscarriages during the s and s increased the likelihood of bisexuality and homosexuality in their unborn children. Professor Swaab, based at the University of Amsterdam, has ignited controversy with his opinions before. Ben Summerskill, chief executive of gay rights organisation Stonewall, said: If being gay is mostly or wholly determined by biological factors prior to birth, it is immoral to condemn or discriminate against lesbians and gay men.
Past SciTechDaily December 12, According to a newly released hypothesis, homosexuality effectiveness not lie in DNA itself. Instead, as an embryo develops, sex-related genes are turned on and off in response to fluctuating levels of hormones in the womb, produced by both mother and child. This benefits the unborn child, however if these epigenetic changes persist once the child is born, and has children of its own, some of these offspring may be homosexual. The scientists published their findings in the journal The Three-monthly Review of Biology.
There are many species exhibiting homosexual traits, including fish and birds, and geneticists have not been masterful to find a gene that is responsible appropriate for sexual orientation.
