Existing data related to the probability of breech presentation suggest that the breech presentation is a consequence of mere filling of the intrauterine space, with the same probability of breech and cephalic presentation. As a consequence, group of cephalic presenting fetuses is heterogenous. Some fetuses randomly assume the cephalic presentation while others assume cephalic presentation ‘intentionally’ for a reason. Before comparing breech and cephalic presenting fetuses/newborns, bias… 

Breech presentation and the cornual-fundal location of the placenta

Cornual-fundal location of the placenta may be an important clue in resolving the etiology of a number of cases of breech presentation at term delivery.

Inner Ear Malformations in Congenital Deafness Are Not Associated with Increased Risk of Breech Presentation

The results of the study suggest that congenital malformations of the vestibular apparatus are not associated with the increased risk of breech presentation at delivery.

Labour Outcomes After Successful External Cephalic Version Compared With Spontaneous Cephalic Version.

A comparison of risk factors for breech presentation in preterm and term labor: a nationwide, population-based case–control study

Breech presentation in preterm labor is associated with obstetric risk factors compared to cephalic presentation, and these risks decrease linearly with the gestational age.


Guinea pig fetuses do not spontaneously or at provocation change presentation after 30 th GD, and this paper concludes that spontaneous changes in fetal presentation during the second half of gestation in guinea pig fetus is not spontaneous.

Elective caesarean section for breech presentation in first pregnancy and subsequent mode of labour.

Women having elective caesarean section for breech presentation in their previous pregnancy had about 1 in 6 chance of having repeat elective cephalic section, indicating mode of labour in current pregnancy decided electively or adopted in emergency.

Scrutiny of processes critical to sustainable healthcare improvement *

The principal finding of this paper—that efficacious treatment of periodontal disease reduces the risk of preterm birth in one high-risk population–is narrow but potentially important.

Machine learning analysis of pregnancy data enables early identification of a subpopulation of newborns with ASD

Pregnancy follow-up measurements might provide an early prognosis of ASD enabling pre-symptomatic behavioral interventions to attenuate efficiently ASD developmental sequels, suggesting an in utero origin of the reported bigger brains of toddlers with ASD.

Pregnancy data enable identification of relevant biomarkers and a partial prognosis of autism at birth

Pregnancy follow-up measurements routinely collected from pregnant mothers and fetuses during gestation and birth are suggested to provide an early prognosis of ASD and implement pre-symptomatic behavioral interventions to attenuate efficiently ASD developmental sequels.

Associations between prenatal indicators of mechanical loading and proximal femur shape: findings from a population-based study in ALSPAC offspring

The results suggest that prenatal skeletal loading, in particular oligohydramnios, may influence adolescent joint shape with associations generally stronger in males.



Breech presentation and tossing a coin: heads or tails.

[Frequency of breech presentation during pregnancy and on full term (author's transl)].

The authors were struck by surprise, when they found that the breech presentation figure, in the context of 997 premature births, was, with high significance, below the level usually recordable from unimplanted pregnancy.

Breech presentation: is it a bad omen?

Evidence that the breech may often be already damaged is compelling and some authors, for example Sabin & Oxorn (1956), have noted that the fetuses of mothers having anticonvulsant therapy for epilepsy more often present by the breeCh.

The characteristics and perils of breech presentation.

To delineate the differences between breech and nonbreech deliveries, the characteristics of 30,359 consecutive, singleton deliveries at one institution were analyzed. Although many of the

Spontaneous cephalic version of breech presentation in the last trimester

Of 140 patients with a breech presentation at delivery 95% were already presenting by the breech in the 32nd week, and spontaneous cephalic version was less likely in pregnancies with extended fetal legs, low birth‐weight, short umbilical cord and primiparity.

[Behavior of fetal position in the 2d half of pregnancy in labor with breech and vertex presentations].

In a retrospective analysis, presentation behavior during pregnancy of 501 infants with breech presentation at birth was compared with that of a control population (n = 520) with vertex presentation

Can breech presentation at birth be predicted from ultrasound examinations during the second or third trimesters?

Does a Probability of Breech Presentation of More Than 50% Exist Among Diseases and Medical Conditions?

Twin gestations in a uterus with 2 bodies decrease the probability of breech presentation, and the odds ratio and chi-square test for differences in probabilities show a significantly lower incidence.
