Prenatal testing among women pregnant after assisted reproductive techniques in Denmark 1995-2000: a national cohort study

Abstract

ART pregnancies represent a group of high-risk pregnancies with regard to chromosomal aberrations, but nevertheless their uptake of prenatal testing was low. ICSI pregnancies compared with IVF pregnancies had a higher rate of chromosomal abnormalities, even though the average maternal age was lower.

Rhombencephalosynapsis in a severely polymalformed fetus with non-mosaic tetrasomy 9p, in intracytoplasmic-sperm-injection pregnancy

“…Furthermore, albeit comparison of fetuses naturally conceived and IVF pregnancies, ICSI pregnancies describes an higher risk for chromosomal anomalies [9][10], this is the first description of tetrasomy 9p in an ART pregnancy. Although pregnant women after ART are generally older than women with spontaneously conceived pregnancies, at present no clear correlation between tetrasomy 9p occurrence and advanced maternal age is reported [11].…”

Clinical outcomes and development of children born after intracytoplasmic sperm injection (ICSI) using extracted testicular sperm or ejaculated extreme severe oligo-astheno-teratozoospermia sperm: a comparative study

“…Although ICSI was initially developed, and has been shown to be an effective treatment for male factor infertility (19), because of the lack of natural selection of sperm in the ICSI procedure, researchers and clinicians have reason to be concerned about its use and the health of the children born using this technique (20)(21)(22)(23).…”
