An article explaining about how stress can have a detrimental part due conception and the more stressed you are the more likely you are to have a girl duet to the increase hormone from stress called cortisol appears to cut the odds of having a boy. And a boy baby is actually weaker than a girl baby so is less likely to survive in a stressed out conception.
- Women who are stressed while trying for a baby are more likely to have girls
- those who were under pressure at home, work or in their love life in the weeks or months before becoming pregnant had higher than usual odds of giving birth to a daughter rather than a son.
- The finding, by Oxford University and U.S. researchers, means the economic downturn could see more women give birth to daughters.
- For instance, in the months after the 9/11 terrorist attacks, the number of boys born in New York plunged, while the economic chaos that followed the collapse of the Berlin Wall saw far fewer boys born than expected in the former East Germany in 1991.
- 338 women from around the UK who were trying to get pregnant kept diaries about their lives and sex lives and filled in questionnaires about how stressed they felt
- . Levels of stress hormones including cortisol were measured in the months before pregnancy.
- Of the babies born, 58 were boys and 72 were girls. Normally, in Britain 105 boys are born for every 100 girls.
- It isn’t known why high levels of cortisol ppear to cut the odds of having a boy.
- The gender of a baby is determined by the chromosomes in the father’s sperm and so is set at conception.
- Previous work by Dr Pyper has blamed stress for lengthening the time it takes to conceive.
- For instance, nutrition or simple biology may play a part. Past research has shown that dominant women are more likely to have sons – perhaps because their higher levels of testosterone ‘prime’ their eggs to make fertilisation with male sperm more likely.
