Twins are by far the most common form of multiple births in humans. The U.S. Centers for Disease Control and Prevention report more than 132,000 sets of twins out of 3.9 million births of all kinds each year, about 3.4%, or 1 in 30. [5] Compared to other multiple births, twin births account for 97% of them in the US. [6]
This is a list of multiple births, consisting of notable higher order (4+) multiple births and pregnancies. Twins and triplets are sufficiently common to have their own separate articles. With the use of reproductive technology such as fertility drugs and in vitro fertilization (IVF) such births have become increasingly common. This list ...
The major complication of IVF is the risk of multiple births. This is directly related to the practice of transferring multiple embryos at embryo transfer. Multiple births are related to increased risk of pregnancy loss, obstetrical complications, prematurity, and neonatal morbidity with the potential for long term damage. Strict limits on the ...
Triplet and higher multiple births nosedive. In 2004, of the people younger than 35 who gave birth with the help of IVF, 32.7% delivered twins, and 4.9% delivered triplets, according to doctors at ...
Low birth weight and preterm birth are strongly associated with many health problems, such as visual impairment and cerebral palsy. Children born after IVF are roughly twice as likely to have cerebral palsy. [21] Sperm donation is an exception, with a birth defect rate of almost a fifth compared to the general population. It may be explained by ...
Midwifery guidance, treatment, and care have been related to better birth outcomes. Diminishing racial inequities in health is an increasingly large public health challenge in the United States. Despite the fact that average rates have decreased, data on neonatal mortality demonstrates that racial disparities have persisted and grown.
Steptoe and Edwards started collaborating in human IVF research in 1968. [3] In 1977, Steptoe and Edwards successfully carried out a pioneering conception which resulted in the birth of the world's first baby to be conceived by IVF, Louise Brown, on 25 July 1978 in Oldham General Hospital, Greater Manchester, UK.
Because a single placenta has difficulty supporting multiple fetuses, in such cases a selective reduction to improve the likelihood of survival for the remaining fetus or fetuses may be indicated. [1] [2] Selective reduction is the practice of reducing the number of fetuses in a multiple pregnancy, such as quadruplets, to a twin or
