File:Entanglement of cord in twins.jpg
- umbilical cord accidents
- Prolapsed umbilical cord – Prolapse of the umbilical cord happens when the foetus is not in a correct position in the pelvis. Membranes rupture and the cord is pushed out through the cervix. When the fetus pushes on the cervix, the cord is compressed and blocks blood and oxygen flow to the fetus. The pregnant woman has approximately 10 minutes to get to a doctor before there is any harm done to the fetus.
- Monoamniotic twins – These twins share the same placenta and the same amniotic sac and therefore can interfere with each other's umbilical cords. When entanglement of the cords is detected, it is highly recommended to deliver the foetuses as early as 31 weeks.
- Umbilical cord length – A short umbilical cord (<30 cm) can affect the foetus in that foetal movements can cause cord compression, constriction, and rupture. A long umbilical cord (>72 cm) can affect the foetus depending on the way the foetus interacts with the cord.{{cite web | vauthors = Brennan D | date = 5 March 2021 |title=What Is Umbilical Cord Prolapse? |url=https://www.webmd.com/parenting/what-is-umbilical-cord-prolapse |access-date=2022-04-27 |website=WebMD |language=en}} Some foetuses grasp the umbilical cord but it is yet unknown as to whether a foetus is strong enough to compress and stop blood flow through the cord. Also, an active foetus, one that frequently repositions itself in the uterus can accidentally entangle itself with the cord. A hyperactive foetus should be evaluated with ultrasound to rule out cord entanglement.
- Cord entanglement – The umbilical cord can wrap around an extremity, the body or the neck of the foetus. When the cord is wrapped around the neck of the fetus, it is called a nuchal cord. These entanglements can cause constriction of blood flow to the fetus. These entanglements can be visualized with ultrasound.
- Torsion – This term refers to the twisting of the umbilical around itself. Torsion of the umbilical cord is very common (especially in equine stillbirths) but it is not a natural state of the umbilical cord. The umbilical cord can be untwisted at delivery. The average cord has three twists.
- Smoke inhalation – If a pregnant woman gets trapped in a building fire, the smoke and fumes can kill a foetus.{{cn|date=September 2023}}

There are a number of definitions for stillbirth.{{cite web |title=Stillbirth: Definition, Causes & Prevention |url=https://my.clevelandclinic.org/health/diseases/9685-stillbirth |access-date=2022-04-27 |website=Cleveland Clinic}} To allow comparison, the World Health Organization uses the ICD-10 definitions and recommends that any baby born without signs of life at greater than or equal to 28 completed weeks' gestation be classified as a stillbirth.{{Rp|location=Overview tab}} The WHO uses the ICD-10 definitions of "late fetal deaths" as their definition of stillbirth. Other organisations recommend that any combination of greater than 16, 20, 22, 24 or 28 weeks gestational age or 350 g, 400 g, 500 g or 1000 g birth weight may be considered a stillbirth.{{cite journal | vauthors = Nguyen RH, Wilcox AJ | title = Terms in reproductive and perinatal epidemiology: 2. Perinatal terms | journal = Journal of Epidemiology and Community Health | volume = 59 | issue = 12 | pages = 1019–1021 | date = December 2005 | pmid = 16286486 | pmc = 1732966 | doi = 10.1136/jech.2004.023465 | quote = There is probably no health outcome with a greater number of conflicting, authoritative, legally mandated definitions. The basic WHO definition of fetal death is the intrauterine death of any conceptus at any time during pregnancy. However, for practical purposes, legal definitions usually require recorded fetal deaths to attain some gestational age (16, 20, 22, 24, or 28 weeks) or birth weight (350, 400, 500, or 1000 g). In the US states, there are eight different definitions by combinations of gestational age and weight, and at least as many in Europe. }}
The term is often used in distinction to live birth (the baby was born alive, even if they died shortly thereafter) or miscarriage (early pregnancy loss). The word miscarriage is often used incorrectly to describe stillbirths. The term is mostly used in a human context; however, the same phenomenon can occur in all species of placental mammals.
=Constricted umbilical cord=
When the umbilical cord is constricted (q.v. "accidents" above), the fetus experiences periods of hypoxia, and may respond by unusually high periods of kicking or struggling, to free the umbilical cord.{{cite web |title=halden fgr experiments: Topics by Science.gov |url=https://www.science.gov/topicpages/h/halden+fgr+experiments |access-date=2022-04-27 |website=www.science.gov}} These are sporadic if constriction is due to a change in the fetus' or mother's position, and may become worse or more frequent as the fetus grows.{{cite book | vauthors = Raines DA, Cooper DB | chapter = Braxton Hicks Contractions |date=2022 |url=http://www.ncbi.nlm.nih.gov/books/NBK470546/ | title = StatPearls |place=Treasure Island (FL) |publisher=StatPearls Publishing |pmid=29262073 |access-date=2022-04-27 }} Extra attention should be given if mothers experience large increases in kicking from previous childbirths, especially when increases correspond to position changes.{{cite journal | vauthors = Beall MH, Ross MG |date=2021-10-16 | veditors = Talavera F |title=Umbilical Cord Complications: Overview, Cord Length, Single Umbilical Artery |url=https://emedicine.medscape.com/article/262470-overview | journal = Medscape }}
Regulating high blood pressure, diabetes and drug use may reduce the risk of a stillbirth. Umbilical cord constriction may be identified and observed by ultrasound, if requested.{{cite journal | vauthors = Menezes EV, Yakoob MY, Soomro T, Haws RA, Darmstadt GL, Bhutta ZA | title = Reducing stillbirths: prevention and management of medical disorders and infections during pregnancy | journal = BMC Pregnancy and Childbirth | volume = 9 | issue = Suppl 1 | pages = S4 | date = May 2009 | pmid = 19426467 | pmc = 2679410 | doi = 10.1186/1471-2393-9-S1-S4 | doi-access = free }}
Some maternal factors are associated with stillbirth, including being age 35 or older, having diabetes, having a history of addiction to illegal drugs, being overweight or obese, and smoking cigarettes in the three months before getting pregnant.{{cite news | url=https://www.cbsnews.com/news/studies-identify-stillbirth-risk-factors-causes/ | work=CBS News | title=Studies identify stillbirth risk factors, causes | date=December 14, 2011 | author=WebMD | access-date=2013-08-06 | url-status=live | archive-url=https://web.archive.org/web/20130524214319/http://www.cbsnews.com/8301-500368_162-57342588/studies-identify-stillbirth-risk-factors-causes/ | archive-date=May 24, 2013 }}

Delivery
In single stillbirths, common practice is to induce labor for the health of the mother due to possible complications such as exsanguination. Induction and labor can take 48 hours. In the case of various complications such as preclampsia, infections, multiples (twins), emergency Cesarean may occur.{{cite web|url=https://www.tommys.org/baby-loss-support/stillbirth-information-and-support/giving-birth-stillborn-baby|title = Preparing for labour and birth with a stillborn baby | location = London | work = Tommy's}}

The vast majority of stillbirths worldwide (98%) occur in low- and middle-income countries, where medical care can be of low quality or unavailable. Reliable estimates calculate that, yearly, about 2.6 million stillbirths occur worldwide during the third trimester.

:"Fetal death" means death prior to the complete expulsion or extraction from its mother of a product of human conception, irrespective of the duration of pregnancy and which is not an induced termination of pregnancy. The death is indicated by the fact that after such expulsion or extraction, the fetus does not breathe or show any other evidence of life, such as beating of the heart, pulsation of the umbilical cord, or definite movement of voluntary muscles. Heartbeats are to be distinguished from transient cardiac contractions; respirations are to be distinguished from fleeting respiratory efforts or gasps.

The above definitions apply within those Acts thus other legislation will not necessarily be in identical terms.
s.2 of the 1953 Act requires that registration of a birth takes place within 42 days of the birth except where an inquest takes place or the child has been "found exposed" in which latter case the time limit runs from the time of finding.

The CDC states that, in the US, a stillbirth is typically defined as the loss of a fetus during or after the 20th week of pregnancy. Stillbirths can further be classified as early (occurring between week 20 and week 27 of pregnancy), late (occurring between week 28 and week 36 of pregnancy), and term (occurring during or after week 37 of pregnancy). In the US, approximately 21,000 babies are stillborn annually, and stillbirth affects around 1 in 175 births.{{cite web |title=What is Stillbirth? |url=https://www.cdc.gov/ncbddd/stillbirth/facts.html |website=Centers for Disease Control and Prevention |date=29 September 2022 |access-date=16 February 2023}}
The federal guidelines recommend reporting those fetal deaths whose birth weight is over 12.5 oz (350 g), or those more than 20 weeks gestation. Forty-one areas use a definition very similar to the federal definition, thirteen areas use a shortened definition of fetal death, and three areas have no formal definition of fetal death. Only 11 areas specifically use the term 'stillbirth', often synonymously with late fetal death; however, they are split between whether stillbirths are "irrespective of the duration of pregnancy", or whether some age or weight constraint is applied. A movement in the U.S. has changed the way that stillbirths are documented through vital records. Previously, only the deaths were reported. However, 27 states have enacted legislation that offers some variation of a birth certificate as an option for parents who choose to pay for one.{{cite web |title=Convention on the Rights of the Child text |url=https://www.unicef.org/child-rights-convention/convention-text |access-date=2022-04-28 |website=www.unicef.org |language=en}} Parents may not claim a tax exemption for stillborn infants, even if a birth certificate is offered. To claim an exemption, the birth must be certified as live, even if the infant only lives for a very brief period.{{cite journal | vauthors = Haupt WF, Hansen HC, Janzen RW, Firsching R, Galldiks N | title = Coma and cerebral imaging | journal = SpringerPlus | volume = 4 | pages = 180 | date = 2015-04-16 | pmid = 25984436 | pmc = 4424227 | doi = 10.1186/s40064-015-0869-y | doi-access = free }}
After Dobbs v. Jackson Women's Health Organization, some states restricted women's access to abortion, even when the pregnancy is nonviable.{{cite web |last1=Tawfik |first1=Nadia |title=She was denied an abortion in Texas - then she almost died |url=https://www.bbc.com/news/world-us-canada-65935189 |website=BBC News |access-date=31 July 2024}} Legal restrictions on medications and procedures that have been used for abortions may also impact treatment options for women undergoing a miscarriage or stillbirth.{{cite web |last1=Ranji |first1=Usha |last2=Salganicoff |first2=Alina |last3=Sobel |first3=Laurie |title=Dobbs-era Abortion Bans and Restrictions: Early Insights about Implications for Pregnancy Loss |url=https://www.kff.org/womens-health-policy/issue-brief/dobbs-era-abortion-bans-and-restrictions-early-insights-about-implications-for-pregnancy-loss/ |website=KFF |access-date=31 July 2024}}
