Smoking Harm The Fetus

Amsterdam, The effects of smoking on health has become common knowledge. In addition to causing problems in cardiovascular health and cancer , smoking can also cause impotence in men. While in pregnant women, smoking can cause disorders of pregnancy and the fetus. According to a study of neurobiology, sexuality in fetuses affected her mother smoked cigarettes .

"Sexuality fetuses affected by lifestyle led by its mother," Professor Dick Swaab said in his new book, as quoted by the Mirror on Tuesday ( 01/21/2014 ) .

69 years scientists from the University of Amsterdam believes that heterosexuality or homosexuality are determined in the womb. According to him, pregnant women who smoke may increase their chances of being a homosexual .

For decades, the origins of sexual orientation into the debate . Some argue that homosexuality is a lifestyle choice, while others argue that sexual orientation is influenced by upbringing. But in the book 'We Are Our ​​Brains', Prof Swaab expressly stated there was no evidence related to the statement .

Instead, the doctor who is an expert on the brain have shown that smoking and the synthetic hormones can increase the likelihood of women becoming lesbian or bisexual. Meanwhile lifestyle fond of drinking alcohol and taking drugs while pregnant impact on the decline in IQ of children.

In his book, which was considered controversial by some of these parties, mentioned brain development during pregnancy altered by the presence of the smallest chemical changes. If a woman gave birth to a boy after previously having a boy as well, then the chances of her baby being gay becomes larger.

"Exposure to prenatal nicotine or amphetamine also increases the likelihood peremouan be a lesbian, "said Prof Swaab.

Not only that, pregnant women who suffer from stress are also more likely to give birth to children homosexual. This is due to the stress hormones affect the production of sex hormones in the fetus.

"The more the brother owned, the opportunity to be a homosexual to be larger, "said Prof Swaab while explaining it is influenced also by the mother's immune response to a substance that is produced by the male fetus in the womb. Well, the response was stronger in every pregnancy .

While the previous study called the women who took the synthetic estrogen between 1939 and 1960 in order to reduce the risk of miscarriage have a better chance to have a girl who is bisexual or lesbian. (Em/report)
