AI synopsis

What people are saying

The overall discussion reveals a strong curiosity and acceptance of the research, with posts citing specific examples, such as families with multiple children of the same sex (e.g., María's case of having three daughters) and referencing the genetic and age-related factors that influence this phenomenon. The tone varies from scientific to conversational, highlighting both academic interest and real-world implications, which underpins the high scores in interest and impact.

AgreementModerate agreement

Most discussions accept that the study suggests sex at birth is influenced by factors like genetics and maternal age, challenging the idea of a purely random process.

InterestHigh interest

Posts demonstrate high interest, referencing specific findings, such as the influence of maternal age and genetic markers, and sharing links to the original study.

EngagementHigh engagement

Many users reference the details, methods, and implications, engaging deeply with concepts like weighted coin tosses and genetic predispositions.

ImpactHigh impact

The discussion indicates the study could significantly alter how people perceive biological randomness in sex determination, potentially affecting societal views and family planning debates.

Abstract in brief

  • Some families tend to have children of only one sex, raising questions about the randomness of sex at birth.
  • The study analyzed data from over 58,000 women and found that offspring sex follows a beta-binomial distribution, meaning each family has a distinct likelihood of having male or female children, similar to a weighted coin toss.
  • Maternal factors, such as age and specific genetic markers, influence the likelihood of having children of only one sex.

Sex at birth may not be purely random, according to a new @ScienceAdvances study. Instead, each family’s likelihood of having only male or only female children is a “weighted coin toss” influenced by maternal age and genetics. https://t.co/msMvLfLuuz https://t.co/s0piZutfDB

子供の性別は50%の確率で男か女かに割り振られると思ってたけど、そうとも言えないっぽい。 男の子が3連続で産まれた場合、4人目は61%の確率で男の子で、3連続で女の子ならその次は58%の確率で女の子になるらしい。 出生比率自体は半々でも家庭単位だと偏るんだとか。 https://t.co/NVOq43fUwA

Neat. Though a newborn's sex has an approximate 50% chance of being either or at birth, odds may change for their prospective siblings. Mothers who had three or more children were more likely to have either all girls or all boys, and age may play a role. https://t.co/xyvgloCyxr

生男生女并不随机 哈佛大学的研究团队分析了 1956-2015 年 58007 名有过两次及以上生育的女性,结果发现一个家庭更容易出生单一性别的孩子,母亲的年龄越大越容易出现这种情况 (29 岁比 22 岁只生单一性别的概率高出 13%)。 https://t.co/kbhPAmrC6L https://t.co/HpezqZ1mXt
