Perinatal risks after IVF and ICSI.

چکیده
Pregnancies that occur after infertility treatment, particularly after assisted reproduction, constitute high-risk pregnancies. Occurrences of conditions such as high blood pressure, preeclampsia, growth retardations and bleeding are higher in comparison with the norm of spontaneously entered pregnancies. The rate of premature births and the frequency of intrauterine deaths are much higher than the average for all pregnancies. Furthermore, pregnancies resulting from in - vitro fertilisation (IVF) have significantly higher rates of requiring induced labour or caesarean section. However, it is to be assumed that these complications and unfortunate developments are not caused by extracorporeal fertilisation itself, but rather are due to the frequency of multiples and to the risk factors of the women involved. These women are, on average, older and there are often more problems with cycle irregularities, uterine anomalies and obesity than in the total collective of all pregnancies. The methods of modern reproductive medicine often bring a higher rate of multiple pregnancies. The clinical problem of multiple pregnancies is, above all, the raised rate of premature births and intrauterine growth retardations that contribute to the significantly higher rate of morbidity and mortality for these children. The slightly higher rate of congenital defects after IVF and intracytoplasmic sperm injection (ICSI) are also attributed more to the risk profile of the parents and less to the techniques themselves. The most important and easy-to-avoid complication is the multiple pregnancy, and it should be our goal to lower this rate even further.

Obstetric and perinatal outcomes in singleton pregnancies resulting from IVF/ICSI: a systematic review and meta-analysis.
BACKGROUND Earlier reviews have suggested that IVF/ICSI pregnancies are associated with higher risks. However, there have been recent advances in the way IVF/ICSI is done, leading to some controversy as to whether IVF/ICSI singletons are associated with higher perinatal risks. The objective of this systematic review was to provide an up-to-date comparison of obstetric and perinatal outcomes of ...

BACKGROUND Although the increased risk for perinatal morbidity and mortality of babies born after ART is largely attributed to a higher rate of multiple gestations, a significantly worse perinatal outcome for singleton pregnancies following ART compared to pregnancies after natural conception has been reported as well. Most studies only include IVF/ICSI pregnancies; studies describing the perin...
