ultrasound sonography
Ultrasound sonography is a prenatal medical procedure in which high-frequency sound waves are directed into the pregnant woman’s abdomen
brain-imaging techniques
The development of brain-imaging
techniques have led to increasing use of fetal MRI to diagnose fetal malformations
chorionic villus sampling
Chorionic villus sampling (CVS)
is a prenatal medical procedure in which a small sample of the placenta is removed
amniocentesis
Amniocentesis is a prenatal medical procedure in which a sample of amniotic
fluid is withdrawn by syringe and tested for chromosomal or metabolic disorders
between the 15th and 18th week

- The current blood test is called the triple screen because it measures
three substances in the mother’s blood.
-between the 15th and 18th week
fetal sex determination
11-13 week
infertility
the inability to conceive a child after 12 months of regular intercourse without contraception.
-not being able to get pregnant-
In vitro fertilization (IVF)
a process in which eggs and sperm are
combined in a laboratory dish by experts.
