Prenatal screening and diagnosis of chromosomal abnormalities especially Down’s syndrome in IVF pregnancies are complicated by higher maternal age, a high multiple pregnancy rate, a high risk of a vanishing twin and an increased risk of chromosomal abnormalities, particularly in pregnancies after ICSI. The electronic search retrieved citations, 96 of which were evaluated in detail and 57 were then excluded for not meeting the selection criteria.
A total of 61 articles were finally selected for review. Correction factors have been developed and should be used when screening for Down’s syndrome in singleton pregnancies. Whether the use of a correction factor for mode of conception in the risk calculations for Down’s syndrome in twin pregnancies is valid has not been fully elucidated. In vanishing twin pregnancies with a second gestational sac with a dead fetus, first trimester screening should be based solely on the maternal age and the nuchal translucency scan as biomarkers are significantly altered in these cases.
As prenatal screening for chromosomal abnormalities particularly Down’s syndrome using maternal serum and sonographic markers has become a routine part of antenatal care in many countries, it has also become accessible to women pregnant after IVF. However, several issues complicate prenatal screening in IVF pregnancies: the mean maternal age that is higher than in women who conceive without fertility treatment, a higher multiple pregnancy and vanishing twin rate that is observed and pregnancies conceived after ICSI may have a higher rate of chromosomal abnormalities Bonduelle et al.

Most pregnancies last around 40 weeks or 38 weeks from conception , so typically the best way to estimate your due date is to count 40 weeks, or days, from the first day of your last menstrual period LMP.
