Chorionic

This change of position is regulated by the male sex hormone testosterone, the secretion of which is stimulated by the hormone called chorionic gonadotropin exuded by the placenta.

The test is uncomfortable and carries a small risk of miscarriage, as does another invasive test for genetic disorders called chorionic villus sampling, or CVS, that samples tissue from the placenta. ❋ Amy Dockser Marcus (2011)

Whether or not to have amniocentesis—or a related test called chorionic villus sampling—is a difficult decision for many expectant parents. ❋ Unknown (2011)

They consist of things like amniocentesis, something known as chorionic villus sampling. ❋ Unknown (2003)

Dr. Verlinsky helped pioneer in the U.S. a prenatal diagnosis technique known as chorionic villus sampling, which screens fetuses for genetic and chromosomal disorders at 10 weeks, at least six weeks earlier than the test known as amniocentesis. ❋ Unknown (2009)

The cell sample is taken from the placenta using a pre-natal biopsy called chorionic villus sampling (CVS). ❋ Unknown (2009)

The two chemical hormones commonly measured to provide information on the pregnancy status of miniature mares are pregnant mare serum gonadotrophin (PMSG), which is frequently now called chorionic gonadotrophin (eCG), and oestrone sulphate (see main story for more information). ❋ Unknown (2009)

Historically, obstetricians recommended that pregnant women age 35 or older get an amnio (or a related procedure, called chorionic villus sampling). ❋ Unknown (2008)

Invasive tests, such as chorionic villus sampling and amniocentesis, give parents definitive answers about certain chromosomal abnormalities. ❋ Keith Samuels Vail Daily Medical Correspondent Vai (2010)

Sometimes it's an earlier test called CVS, or chorionic villus sampling, which collects a bit of tissue from the placenta. ❋ Unknown (2011)

But the tests aren't without risk, as they involve putting a needle into the womb to either withdraw fluid (amniocentesis) or remove a small piece of the placenta (chorionic villus sampling). ❋ Unknown (2011)

He injected children with Frohlich's syndrome -- a condition characterized by obesity and slow development of reproductive organs -- with human chorionic gonadotropin. ❋ M.D. Glenn D. Braunstein (2011)
