"壓力能給你女嬰嗎？"

即便受孕時就已經決定了嬰兒的性別，孕婦處在較高的壓力下生出女嬰的可能性會增加。

這並不表示壓力會改變嬰兒的性別。這意味著處在高壓時期，男性胚胎較有可能會流產，也就是說，如果胚胎是女生你較有可能撐過懷孕期。科學家發現有這種趨勢，當多數人口處於高壓狀態，像是地震達芮氏規模7.9的2005年智利大地震。住在震央愈近的婦女產出較多女嬰，相較於男嬰。此外，早產的數量也會隨著孕婦面臨的壓力程度而增加。

某些原因可能是男性胚胎較大，傾向需要母親更多的養分。當孕婦處於壓力之下，她自己的身體使用這些養分，使得胚胎處於營養短缺的情形。這造成流產率增加。而且，女性胚胎比男性胚胎更能適應改變(且較有壓力)的環境，並且更有可能在壓力較大的時期存活。

(Health) Can Stress Bring You A Baby Girl

While the sex of your baby is determined at conception, the likelihood of delivering a baby girl increases if the mother is exposed to higher levels of stress.

This doesn't mean that stress changes the sex of the baby.What it means is that during periods of high stress, boy fetuses are more likely to miscarry, meaning that you are more likely to carry a baby to term if it is a girl.Scientists noticed these kinds of trends during times when large populations were under high stress, such as the 2005 earthquake in Chile, which was a magnitude of 7.9 on the Richter scale.The closer women lived to the epicenter, the more baby girls were born, compared to baby boys. In addition, the number of premature births also increased depending on the levels of stress the mother faced.

Some reasons for this would be the fact that boy fetuses are larger, and tend to need more resources from the mother. When the mother is under stress, her own body uses these resources, leaving the fetus short of what it needs.This makes the chances of miscarrying increase. Also, girl fetuses can adapt to a changing (and more stressful) environment better than boys can, and are more likely to survive higher times of stress.
