Complications in pregnancies achieved by assisted reproduction

Perinatal complications of assisted reproduction.

The main perinatal complications of assisted reproduction include congenital malformation, chromosomal aberrations, multiple pregnancy, and prematurity. Earlier studies and in vitro fertilization (IVF) registries showed that there was no increased incidence of congenital malformations in children conceived by IVF/intracytoplasmic sperm injection (ICSI). However, a large Australian study has fou...

First trimester biochemical screening for Down's syndrome in singleton pregnancies conceived by assisted reproduction.

BACKGROUND Serum biochemical markers [free betahCG (fbetahCG); pregnancy-associated plasma protein-A (PAPP-A)] used in first trimester Down's syndrome screening have not been fully investigated in pregnancies achieved by assisted reproduction techniques. We present data on pregnancies conceived by all types of assisted reproduction techniques, including pregnancies following ovum donation (OD) ...

Pregnancy Complications and Neonatal Outcomes in Multiple Pregnancies: A Comparison between Assisted Reproductive Techniques and Spontaneous Conception

First-trimester serum marker distribution in singleton pregnancies conceived with assisted reproduction.

OBJECTIVE To evaluate marker distribution of free beta-human chorionic gonadotrophin (fbeta-hCG) and pregnancy-associated plasma protein-A (PAPP-A) in singleton pregnancies conceived by assisted reproduction techniques (ART). METHODS In vitro fertilization (IVF) (n = 203) and intracytoplasmic sperm injection (ICSI) (n = 192) cases from a database of 14 645 first-trimester combined tests (over...

First trimester serum angiogenic/anti-angiogenic status in twin pregnancies: relationship with assisted reproduction technology.

BACKGROUND The risk of pre-eclampsia (PE) increases in twin pregnancies, especially when assisted reproduction technologies (ART) are used. The aim of this study was to assess angiogenic/anti-angiogenic factors in maternal serum in the first trimester of twin pregnancies and establish if the mode of conception influences angiogenic status. METHODS This prospective study enrolled women with tw...
